1. Important Safety Information
NOTE: Before using the inverter, read and save this manual.
1-1. General Safety Precautions
1-1-1. Do not expose the inverter to rain, snow, spray, bilge or dust. To reduce risk of hazard, do not cover or obstruct the ventilation openings. Do not install the inverter in a zero-clearance compartment. Overheating may result. Allow at least 12" of clearance around the inverter for air flow. Make sure that the air can circulate freely around the unit. A minimum air flow of 145CFM is required. 1-1-2. To avoid risk of fire and electronic shock, make sure that existing wiring is in good electrical condition and that the wire is not undersized. Do not operate the inverter with damaged or substandard wiring. 1-1-3. This equipment contains components which may produce arcs and/or sparks. To prevent fire and/or explosion do not install in compartments containing batteries or flammable materials or in a location which require ignition protected equipment. This includes any space containing gasoline-powered machinery, fuel tanks, or joints, fittings, or other connection between components of the fuel system. See Warranty for instructions for servicing the inverter. 1-1-4. Do not disassemble the Inverter Charger. It contains no user-serviceable parts. Attempting to service the Inverter Charger yourself may result in electrical shock or fire. Internal capacitors remain charged after all power is disconnected. 1-1-5. To reduce the risk of electrical shock, disconnect both AC and DC power from the Inverter Charger before attempting any maintenance or cleaning. Turning off controls will not reduce this risk
CAUTION: Equipment damage The output side of the inverter's AC wiring should at no time be connected to public power or a generator. This condition is far worse than a short circuit. If the unit survives this condition, it will shut down until corrections are made. Installation should ensure that the inverter's AC output is, at no time, connected to its AC input.
1-2. Precautions When Working with Batteries
1-2-1. If battery acid contacts skin or clothing immediately wash with soap and water. If acid enters eyes immediately rinse eyes with running cold water and seek immediate medical attention. 1-2-2. Never smoke or allow a sparks or flames near the battery. 1-2-3. Do not drop a metal tool on the battery. The resulting spark or short-circuit on the battery will cause an explosion. 1-2-4. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a battery. A battery produces a short-circuit current high enough to weld any metal objects and will cause a severe burn. 1-2-5. To reduce the risk of injury, charge only deep-cycle lead acid, lead antimony, lead calcium gel cell, absorbed mat, LIFEPO4 lithium or NiCad/NiFe type rechargeable batteries. Other types of batteries may swell or burst causing personal injury and damage.

2. Introduction
2-1. General Information
The Global LF Series Pure Sine Wave Inverter Charger product line is a combination of an inverter, battery charger and auto AC transfer switch in one unit and has a peak conversion efficiency of 88%. It is packed with unique features and is one of the most advanced inverter chargers on the market today. It features power factor correction, sophisticated multi-stage charging and pure sine wave output with unprecedentedly high surge capability to meet demanding power needs of inductive loads without damaging the equipment.
When utility AC power cuts off (or falls out of acceptable range), the transfer relay is de-energized and the load is automatically transferred to Inverter mode. Once the qualified AC power is restored the relay is reenergized and the load is automatically reconnected to AC bypass mode. NOTE THE BYPASS RATING OF THE INVERTER (page 33) AND DO NOT EXCEED. DAMAGE MAY OCCUR AND VOID THE WARRANTY. The Global LF Series Inverter is equipped with a powerful four stage smart charger and includes an auto generator start feature. The overload capacity of the inverter charger products is 300% of continuous output for up to 20 seconds to reliably support tools and equipment. This is for inverter mode only. You can NOT bypass the surge rating of the inverter. This may cause permanent damage to the inverter.
Another important feature is that the inverter can be easily customized to Battery priority via a DIP switch. This helps to extract maximum power from the battery in renewable energy systems such as solar and wind. The Global LF Series Pure Sine Wave Inverter is suitable for renewable energy systems in work trucks, RV, marine and emergency appliances.
To get the most out of the power inverter, it must be operated and maintained properly. Please read the instructions in this manual before installing and operating.

2-5. Electrical Performance
2.5.1 Inverter
Topology The Global LF inverter/charger is built according to the following topology. Invert: Full Bridge Topology. Charge: Isolated Boost Topology.
It works bi-directionally: in one direction it converts DC power from the battery to AC power (Inverter Mode) and in the other direction it converts external AC power to DC power to charge the batteries (AC Mode). The same power components are used in both directions, resulting in high-energy transfer efficiency with fewer components.
When operating in inverter mode, the direct current (DC) that enters the inverter from the batteries is filtered by a large input capacitor and switched "On" and "Off" by the Metal Oxide Silicon Field Effect Transistors (MOSFET) at a rate of 50 Hz or 60Hz, in this step the DC is converted to low voltage synthesized sine wave AC using an H-bridge configuration and high frequency PWM (Pulse Width Modulation) technique. It is then directed into the transformer which steps the low AC voltage up to 230 or 120 volts. The unit has a 16bit, 4.9MHZ microprocessor to control the output voltage and frequency as the DC input voltage and/or output load varies.
Because of the high efficiency MOSFETs and the heavy transformers, it outputs PURE SINE WAVE AC with an average THD of 10% (min 3%, max 20% under full linear loads) depending on load connected and battery voltage. The peak DC to AC conversion efficiency of the Global LF series is >88%.
Don't parallel the AC output of the inverters to increase power capacity as they have no stacking functionality.
6

Overload Capacity: The Global LF series inverters have high overload capacities, making it ideal to handle demanding loads.
1. For 110%<Load<125%(±10%), no audible alarm for 14 minutes, beeps 0.5s every 1s in the 15th minute, and Fault (Turn off) after the 15th minute. 2. For 125%<Load<150%(±10%), beeps 0.5s every 1s and Fault (Turn off) after 1 minute. 3. For 300% Load>150%(±10%), beeps 0.5s every 1s and Fault (Turn off) after 20s. Caution: After the inverter is switched on, it takes time for it to self-diagnose and ready to deliver full power. Hence, always switch on the load(s) after a few seconds of switching on the inverter. Avoid switching on the inverter with the load already switched on. This may prematurely trigger the overload protection. When a load is switched on, it may require an initial higher power surge to start. If multiple loads are being powered, they should be switched on one by one so that the inverter is not overloaded by the higher starting surge if all the loads are switched on at once.
2.5.2 AC Charger
The inverter charger is equipped with an active PFC (Power Factor Corrected) multistage battery charger. The PFC feature is used to control the amount of power used to charge the batteries in order to obtain a power factor as close as possible to 1. Unlike other inverters whose max charging current decreases according to the input AC voltage, the Global LF series charger is able to output max current as long as the input AC voltage is in the range of 164-243VAC(95-127VAC for 120V model), and AC frequency is in the range of 48-54Hz(58-64Hz for
60Hz model). The Global LF series inverter has a very rapid charge current available, and the max charge current can be adjusted from 15%-100% (based on model) via a liner switch to the right of the battery type selector. This will be helpful if you are using our powerful charger on a small capacity battery bank. Fortunately, the liner switch can effectively reduce the max charging current to 15-20% of its peak (based on model). Choosing "0" on the Battery Type Selector will disable the charging function.
Caution: Turn the charge current control switch gently to avoid breakage due to over-turning. Not covered under warranty.
There are 3 charging stages: Bulk Charging: (fast charge LED solid) this is the initial stage of charging. While Bulk Charging, the charger supplies the battery with controlled constant current. The charger will remain in Bulk charge until the Absorption charge voltage (determined by the Battery Type selection) is achieved. A software timer will measure the time from A/C start until the battery charger reaches 0.3V below the boost voltage, then take this time asT0 and T0×10 = T1.
Absorb Charging:(fast charge LED blinking) This is the second charging stage when the fast charge LED is flashing and begins after the absorb voltage has been reached. Absorb Charging provides the batteries with a constant voltage and reduces the DC charging current in order to maintain the absorb voltage setting. In this period, the inverter will start a T1 timer; the charger will keep the boost voltage in Boost CV mode until the T1 timer has run out. Then drop the voltage down to the float voltage. The timer has a minimum time of 1 hour and a maximum time of 12 hours.
Float Charging: (float charge LED solid) The third charging stage occurs at the end of the Absorb Charging time. While Float charging, the charge voltage is reduced to the float charge voltage (determined by the Battery Type selection*). In this stage, the batteries are kept fully charged and ready if needed by the inverter.
7

If the AC is reconnected or the battery voltage drops below 12Vdc/24Vdc, the charger will restart the above cycle. If the charge maintains the float state for 10 days, the charger will deliberately reset the cycle to protect the battery.

*Check the required charging specifications with the battery manufacturer. The chart above is just a guide.
De-sulphation The de-sulphation cycle (switch position 8) is a very dangerous setting if you do not know what you are doing. Before attempting to use this cycle you must clearly understand what it does and when and how you would use it.

What causes sulphation? This can occur with infrequent use of the batteries or if the batteries have been discharged low enough that they will not accept a charge. This cycle is a very high voltage charge cycle designed to try to break down the sulphated crust that is preventing the plates from taking a charge and allowing the plates to clean up and accept a charge once again. Charging depleted batteries The Global LF series inverter allows a generator to start up and through power (bypass) after batteries are depleted. See top of page 10 for generator recommendation. For 12VDC models: after the battery voltage goes below 10V and the power switch is kept in the "ON" position and the inverter stays connected to the battery and the battery voltage doesn't drop below 9V, the inverter will be able to charge the battery once qualified AC inputs are present. Before the battery voltage goes below 9VDC, the charging can be activated when the switch is turned to "OFF", then to "ON". When the voltage goes below 9VDC, and you accidentally turn the switch to OFF or disconnect the inverter from the battery, the inverter will not be able to charge the battery once again, because the CPU loses memory during this process. For 24VDC models: multiply all VDC by 2. For 48VDC models: multiply all VDC by 4. Charging current for each model
The charging capacity will go to peak charge rate in approximately 3 seconds. This may cause a generator to drop frequency, making the inverter transfer to battery mode. It is recommended to gradually put the charging load on the generator by switching the charging switch from min to max. Together with the 15s switch delay our inverter gives the generator enough time to spin up. This will depend on the size of the generator and rate of charge. As a general rule, the Bulk Charging Current should be limited to 20% of the capacity of the battery bank. Higher charging current may be used if permitted by the battery manufacturer.

When the power switch is turned to either "Power Save ON" or "Power ON", the inverter is powered on. The Power Saver function is designed to conserve battery power when AC power is not or rarely required by the loads. In this mode, the inverter pulses the AC output looking for an AC load (IE. electrical device). Whenever an AC load (greater than 50-100 watts depending on model) is turned on, the inverter recognizes the need for power and automatically starts inverting and output goes to full voltage. When there is no load (or less than 50-100 watts depending on model) detected, the inverter automatically goes back into search mode to minimize energy consumption from the battery bank. In "Power saver on" mode, the inverter will draw power mainly in sensing moments, thus the idle consumption is significantly reduced. The inverter will detect a load for 250ms every 3 seconds (DOP switch#3 position 1). Note: The minimum power of a load to take inverter out of sleep mode (Power Saver On) is 50 Watts for inverters 1000-3000 watts and 100 Watts for 4000-6000 watts. The Global LF Series is designed with extremely low idle power consumption, only a mere 0.8-1.8% of its rated power.

When in the search sense mode, the green power LED will blink and the inverter will make a ticking sound.
12

At full output voltage, the green power LED will light steadily and the inverter will make a steady humming sound. When the inverter is used as an "uninterruptible" power supply the search sense mode or "Power Saver On" function should be defeated.
Exceptions Some devices when scanned by the load sensor cannot be detected. Small fluorescent lights and inductive loads are the most common example. (Try altering the plug polarity by turning the plug over.) Some computers and sophisticated electronics have power supplies that do not present a load until line voltage is available. When this occurs, each unit waits for the other to begin. To drive these loads either a small companion load must be used to bring the inverter out of its search mode, or the inverter may be programmed to remain at full output voltage (Power On mode).
2.5.6 Protections
AC input over voltage protection/AC input low voltage protection Low battery alarm/high battery alarm Over temperature protection/overload protection Short circuit protection (1s after fault) Back feeding protection
When over temperature /overload occur, after the fault is cleared, the master switch needs to be reset to restart the inverter. The low battery voltage trip point can be customized from a defaulted value of 10VDC to 10.5VDC thru SW1 on the DIP switch. The inverter will go to over temp protection when the heat sink temp. 105ºC(221), and go to fault (shutdown Output) after 30 seconds. The switch needs be reset to activate the inverter. The Global LF series inverter has back feeding protection which avoids presenting an AC voltage on the AC input terminal in inverter mode. When a fault is cleared, the inverter will need to be reset to start working.
*We don't recommend connecting AC input to a GFCI circuit as it will cause the supply GCFI to pop
intermittently and fail to supply power to the charger and bypass power through inverter.
2.5.7 Remote Control
In addition to the switch panel on the front (or top) of the inverter, there are two optional remotes, for some models. An LCD remote panel that provides more detailed info or an LED remote that provides on/off with a few LED indicators. The LCD remote panel connects to the RJ45 port on the DC side of the inverter displays several statuses of the inverter (sold separately Part # REMOTELF). Use with port labeled LCD remote. If you want a more simple on/off remote, consider the LED remote (sold separately Part # REMOTELFLED). Use with port labeled LED remote. Not available on all models.
If an extra switch panel is connected to the inverter via "remote control port", together with the panel on the inverter case, the two panels will be connected and operated in parallel. Whichever first switches from "Off" to "Power saver off" or "Power saver on", it will power the inverter on.
If the commands from the two panels conflict, the inverter will operate according to the following priority: Power saver on> Power saver off> Power off Only when both panels are turned to the "Unit Off" position, will the inverter be powered off. The max length of the cable is 60 feet.
13

Remote LED - REMOTELFLED The remote LED has on/off and power save switch. There are also 3 indicator LEDs for the battery charger, inverter mode and faults.
Remote LCD - REMOTELF The remote LCD displays detailed information of the inverter.

2.5.10 FAN Operation
For 1-3KW models, there is one multiple controlled DC fan which starts to work according to the below logic. For 4-6KW models, there is one multiple controlled DC fan and one AC fan. The DC fan will work in the same way as the 1-3KW models, while the AC fan will work once there is AC output from the inverter. So when the inverter is in power saver mode, the AC fan will work from time to time in response to the pulse sent by the inverter in power saver mode. The Operation of the DC fan at the DC terminal side is controlled by the following logic:

Allow at least 12 inches of clearance around the inverter for air flow. Make sure that the air can circulate freely around the unit. Fan noise level <60db at a distance of 3 feet

2.5.11 DIP Switches
On the DC end of inverter, there are 5 DIP switches that enable users to customize some of the inverter charger's functions.

Low Battery Trip Volt (SW1) Deep discharge of the lead acid battery will cause losses in capacity and early aging. In some applications a different low voltage disconnection level may be preferred. For example, in solar applications, users may intend to have less DOD to prolong the battery life cycle. While for mobile applications, users may intend to have more DOD to fully use the battery capacity available, minimizing onboard weight.
For 12VDC models, the Low Battery Trip Volt is set at 10.0VDC by default. It can be customized to 10.5VDC using SW1. This is to prevent batteries from over-discharging while there is only a small load applied on the inverter. multiply*2 for 24VDC, multiply*4 for 48VDC
AC Input Range(SW2) There are different acceptable AC input ranges for different kinds of loads. For some relatively sensitive electronic devices, a narrow input range of 184-253VAC (100-135V for 120VAC model) is required to protect them. While for some resistive loads that work in a wide voltage range, the input AC range can be customized to 154-264VAC (90-135V for 120VAC model). This helps to power loads with the most AC input power without frequently switching to the battery bank. In order to make the inverter accept dirty power from a generator, put SW2 to position "1", the inverter will bypass an AC input with a wider voltage and frequency (40-70Hz for 50Hz/60Hz). The AC charger will also work in a wider voltage and frequency range (42-68Hz for 50Hz/60Hz).
As mentioned, this will avoid frequent switching between battery and generator, but the low quality power may affect some sensitive loads. The pros and cons should be considered when dealing with sensitive loads.
NOTE: This is for bypass only! The charger has a different voltage range and may not operate at full rated current. Refer to Section 2.5.2 AC Charger.
Power Saver Override ON/OFF (SW3) The factory default for SW3 is Position 0. Position 1 will allow the Power Save feature of the inverter to detect a load for 250ms every 3 seconds. If a load is detected, the inverter will output AC Power. If SW3 is moved to Position 0. This will prevent the sense pulse from being sent out, even if inverter is in Power Save mode via Main Power switch. No power will be output unless Shore Power input is present. Only then will the battery charger and AC throughput operate when SW3 is in Position 0.
Frequency Switch (SW4): The output frequency of the inverter can be set at either 50Hz or 60Hz by SW4. 50Hz most common in Europe and Africa.

AC/Battery Priority (SW5): The inverter charger is designed with AC priority as default. This means, when AC input is present, the battery will charge first, and the inverter will transfer the input AC to power the load. Only when the AC input is stable for a continuous period of 15 days will the inverter start a battery inverting cycle to protect the battery. After 1 normal charging cycle AC throughput will be restored. The AC Priority and Battery Priority switch is SW5. When you choose battery priority, the inverter will invert from battery first and then AC input when battery voltage drops. Only when the battery voltage reaches the low voltage alarm point(10.5V for 12V,21Vdc for 24Vdc, 42Vdc for 48Vdc) will the inverter transfer to AC Input, charge battery, and switch back to battery when the battery is fully charged. This function is most common for wind/solar systems using utility power as back up.
Note: In battery priority mode, when qualified AC inputs for the first time and the battery voltage is below 12.5Vdc (12.5Vdc for 12Vdc, 25Vdc for 24Vdc, 51Vdc for 48Vdc, the inverter will go into battery priority mode only after a cycle of bulk charging and absorb charging is finished. The inverter will not go into float charging mode.
2.5.12 Auto Generator Start
BEFORE YOU USE A GENERATOR, MAKE SURE IT IS SIZED TO HANDLE THE INVERTER. To guarantee the best performance of the built in AC charger and when the AC input is from a generator, the standby generator should be at least 150% higher capacity than the inverter. Operating with an under-rated generator or generator with unqualified wave form may cause premature failure which is not covered under warranty. Example: If you are using a 2000 watt inverter charger, your generator must be 3000 watts or larger. If you are using a 3000 watt inverter charger, your generator must be 4500 watt or larger, and so on.
The inverter is able to start up a generator when battery voltage drops. When the inverter goes into low battery alarm, it can send a signal to start a generator and turn the generator off after battery charging is completed. The auto gen start feature will only work with generators that have an automatic starting function. The generator must have start and stop controls [an electric starter and electric choke (for gasoline units)], and the safety sensors to be able to start and stop automatically. There is an open/close relay that will short circuit the positive and negative cables from a generator start control. The input DC voltage can vary, but the max current the relay can carry is 16 amps. The Auto Gen Start terminal pins are not polarized. These two pins can also be used as dry contacts to send out "Low Battery Voltage" signal to an external alarm device. Use 18 AWG speaker wire for this application.
2.5.13 Other Features
Battery Temperature Sensing
Applying the proper charge voltage is critical for achieving optimum battery performance and longevity. The ideal charge voltage required by batteries changes with battery temperature.
The Battery Temperature Sensor allows the charger to continuously adjust charge voltage based on actual battery temperature. Temperature compensation of charge voltage assures that the battery receives the proper charge voltage as battery temperature varies. The temp sensor sends precise information to the charger, which automatically adjusts voltage to help ensure full battery charge depending on the ambient temperature of your battery.
When the battery voltage is over 104 it will reduce the charging voltage by 0.1Vdc with every degree of temperature rise. AIMS recommends using the battery sensor to protect your batteries and to provide optimal charging. The Bat Temp Sensor attaches to the side of a battery, closest to the negative terminal using electrical tape or silicon.

Battery voltage recovery start After low battery voltage shut off (10V for 12V model or 20V for 24V model or 40V for 48V model), the inverter is able to restore operation after the battery voltage recovers to 13V/26V/52V (with power switch still in the "On" position). This function helps users and saves time and extra labor to reactivate the inverter when the low battery voltage returns to an acceptable range in renewable energy systems. The built in battery charger will automatically reactivate as soon as city/generator AC has been stable for 15 seconds.

WARNING Never leave the loads unattended, some loads (like a heater) may cause accidents in such cases. It is better to shut everything off after low voltage trip than to leave your load on, due to the risk of fire.
Conformal Coating AIMS Power's entire line of Global LF inverters have been processed with a conformal coating on the PCB, making it water, rust, and dust resistant as well as corrosion resistant. While these units are designed to withstand corrosion from the salty air, they are not splash proof.

3 Installation
3.1 Unpacking and Inspection
Carefully remove the inverter charger from its shipping package and inspect all contents. Verify the following items are included: · The PICOGLF Inverter Charger · Red and black DC terminal covers · AC terminal block cover with two Phillips screws · Two Flange nuts and 4 Phillips screws (installed on the DC terminals). · PICOGLF Series Owner's Manual
If items appear to be missing or damaged, contact AIMS Power. If at all possible, keep your shipping box and all packaging. It will help protect your inverter from damage if it ever needs to be returned for service. Save your proof-of-purchase as a record of ownership; it will also be needed if the unit should require warranty work. The serial number is on the side of the inverter and does NOT start with an 8.
21

3-2. Location
Follow all the local regulations to install the inverter. Install the equipment in an INDOOR location that is dry, clean, free from dust, cool and with good ventilation. Working temperature: -14 to 122 | Storage temperature: 40 to 158 | Relative Humidity: 0% to 95, non-condensing | Cooling: forced airc Do not install upside down (top side facing down). CAUTION: Some models are heavy. Use proper lifting techniques during installation to prevent personal injury.
WARNING! The inverter should not be installed in an area that allows dust, fumes, insects or rodents to enter or block the inverter's ventilation openings. This area must also be free from any risk of condensation, water or any other liquid that can enter or fall on the inverter. All inverters have been processed with a conformal coating on the PCB, making them humid, rust, and dust resistant but not completely protected. While these units are designed to withstand corrosion from the salty air, they are not splash proof. DO NOT GET WET. The inverter's life is uncertain if used in these types of environments, and inverter failures under these conditions are not covered under warranty.
Installation Tools / Materials
You will need the following tools to install the inverter and the battery temperature sensor.
Wire stripper Crimping tools for fastening lugs and terminals on DC cables Phillips screwdriver: #2 & slow scredriver 1/4" wide blade Electrical tape or silicone for bat temp sensor Needle-nose pliers Wrench for DC terminals: 9/16"
Materials
You will need the following materials to complete your installation:
Correct size DC battery cables Terminals and/or crimp connectors for DC cables Copper wire for DC grounding: No. 8 AWG. Terminal or crimp connector for DC grounding cable (for 1/4" stud size) AC output and input wire. If the AC ground wire is stranded, each ground wire requires a ring terminal Six 1/4"20 1.25" length steel screws or bolts to mount the inverters
3-3. DC Wiring
It is recommended that the battery bank be kept as close as possible to the inverter. The following is a suggested wiring option for 12 feet of DC cable. Follow the minimum wire size. If the DC cable is longer than 12 feet, increase the size of cable to reduce voltage drop.
WARNING! The inverter charger must be connected to a battery bank in order to turn on and transfer AC power.

Battery cables must be crimped (or preferably, soldered and crimped) copper compression lugs unless aluminum mechanical lugs are used. Soldered connections alone are not acceptable. High quality, UL-listed battery cables are available. These cables are color-coded with pressure crimped, sealed ring terminals.

Battery terminal must be clean to reduce the resistance between the DC terminal and cable connection. A buildup of dirt or oxidation may eventually lead to the cable terminal overheating during periods of high current draw. Use a stiff wire brush and remove all dirt and corrosion from the battery terminals and cables.

Reducing RF interference To reduce the effect of radiated interference, twist the DC cables. To further reduce RF interference, shield the cables with sheathing /copper foil / braiding. Taping battery cables together to reduce inductance Do not keep the battery cables far apart. In case it is not convenient to twist the cables, keep them taped together to reduce their inductance. Reduced inductance of the battery cables helps to reduce induced voltages. This reduces ripple in the battery cables and improves performance and efficiency.

3-4. AC Wiring
The AC terminal is rated for wires of 8 AWG to 20 AWG, we recommend using 10 to 8 AWG wire to connect to the ac terminal block. When in AC mode the AC input power will supply both the loads and AC charger, a thicker wire gauge for AC input is required. Please consult a qualified electrician about the specific wire gauge required in terms of wire material and inverter power. There are several ways of connecting the terminal block depending on the model. All the wirings are CE compliant. call our tech support if you are not sure about how to wire any part of your inverter.
STOP: DON'T WIRE UNTIL YOU CONFIRM THE MODEL NUMBER OF YOUR INVERTER. NOTE WHETHER YOU HAVE A 120 SINGLE PHASE OR 120/240V SPLIT PHASE.

Do not loosen or touch the rear set screws on the terminal block.

WARNING
For split phase models, AC input neutral is not required in wiring. Never connect input neutral to output neutral. Damage will occur and is not covered under warranty. Always switch on the inverter before plugging in any appliance.
WARNING
The output voltage of this unit must never be connected in its input AC terminal, overload or damage may occur. *We don't recommend connecting AC input to a GFCI circuit as it will cause the supplied GCFI to pop intermittently and fail to supply power to the charger and bypass power through inverter. Always switch on the inverter before plugging in any device.
3-5. Grounding
Connect an 8 AWG or bigger copper wire between the grounding terminal on the inverter and the earth grounding system or the vehicle chassis.
3.5.1 Automatic Neutral-to-Ground Connection
All single phase 120Vac inverters are equipped with automatic neutral-to-ground switching. These inverters use an internal relay that automatically connects the AC neutral output to the vehicle/boat's safety ground ("bonding" it) in Inverter Mode and disconnects it ("un-bonding" it) when they have connected to a qualified external AC source.
This design avoids two neutral-to-ground connections from existing at the same time, thereby preventing an electrical shock hazard between the vehicle/boat's neutral and the external AC source's neutral.
26

2 sablienAgt ic
d tion
In some installations, this feature must be disabled. To accommodate these situations, the automatic Neutral-to-Ground Connection system can be defeated, so it will not bond the neutral in any mode of operation. If you are not sure whether you must disable this feature, please refer to local code requirements. There is a section of green wire with the insulated connector at the left side of the AC terminal block. This insulated connector connects the neutral and ground inside the inverter while inverting. Pull the two ends of the insulated connector apart to separate the green wire; this will prevent the neutral and ground from connecting inside this inverter. If possible, use electrical tape to insulate the disconnected ends, move the two ends away from each other and push back out of the way. Typically, when connecting to a house panel (after disconnecting city power from it) is when you would disconnect this connection as a house panel already has the neutral to ground bond. In a standalone system or in a vehicle, you would want to keep this connection.
