FUNCTIONAL DESCRIPTION

The EL100XA is a modular Static Inverter (SI) comprising power module, distribution and batteries in one cabinet. All components are all accessed from the front of the cabinet with all power connections located at the top of the EL100XA cabinet.

AVR: The first stage of the concept uses a single-phase controlled automatic voltage regulator as a form of surge protector. An AVR monitors the voltage constantly to deal with both dips and spikes. This feature includes “Buck” and “Boost” technology to output regulated and controlled voltage at a selectable figure.
CHARGER: In EL100XA Series EL INVERTERs, a controlled charger is used to produce DC voltage for both charging the batteries.

BATTERIES: Batteries are used as reserve DC power supply for the Inverter in case of mains failure. Batteries are connected in series to obtain a DC supply. Batteries are discharged by the inverter during mains failure. The discharged batteries are re-charged by the Rectifier on a constant voltage / current limiting basis, if AC mains power is available.
INVERTER: The Inverter converts the DC BUS voltage supplied by the batteries into a well-regulated, fully digital controlled AC voltage with fixed voltage and frequency. The output of the inverter is used to supply the critical loads connected to the EL INVERTER output.
STATIC TRANSFER SWITCH (STS): This is an electronically controlled transfer switch, which enables the critical load to be connected either to inverter output or to by-pass power source. During normal operation, the load is supplied by the mains output, in case of a mains disturbance or a mains failure the load is automatically transferred to the inverter source

MODES OF OPERATION

Changeover mode

When operating in the ‘changeover’ mode the rectifier is turned on to provide battery charging. The inverter is turned on and operating on standby (off load) The bypass-side of the static switch is turned on to connect the SI OUPUT to the AC INPUT via the internal bypass line. If the utility supply fails, the static switch will transfer the SI OUPUT to the inverter within 10ms. However, as the utility supply is in a failed state the rectifier is inoperative and the inverter will be powered solely from the batteries (see Figure 2.5).

On battery operation

If the mains supply fails, the rectifier turns off but the inverter will continue to operate from battery power until the batteries reach their end-of-discharge voltage; at which point the inverter will shut down and disconnect the SI OUTPUT supply. If the AC INPUT supply is restored before the batteries are fully discharged, the rectifier will turn on automatically to once again power the inverter and recharge the batteries. The whole process of switching between rectifier and battery power is totally transparent to the emergency luminaires.

COMPONENT DESCRIPTION

CABINET

The EL100XA cabinet, shown in Figure 2.3, comprises a power module, distribution, batteries and test panel.

All components can be fitted/removed from the front of the cabinet, making side and rear access unnecessary for servicing or repair.
All the AC and DC power cables are connected to terminals located on the top of the cabinet and two gland plates are provided for top cable entry.

POWER MODULE

The power module is shelf-mounted.

FRONT PANEL

The front panel of the EL-Inverter, consisting of a LCD display, 3 function keys, TEST ON LED, Test Button, allows the complete monitoring of the EL-Inverter status. By using the function keys operator can move on menus.

LED : If “Test On” lamp is lit maintenance test is active.

There are three function keys on front panel these are MAIN CONTROL ON/OFF BUTTON, UP/DOWN SELECT keys help moving on menus.

NOTE : The main control on/off button will provide test function at normal mode, but will become the alarm-reset function in battery mode.

FRONT PANEL MENU DESCRIPTIONS

	TEMP.	℃	Inverter internal temperature.
	Selection Button for mode & value All the operation data will be displayed on LCD screen. By selecting the required mode (upward or downward), the related value will be displayed.

AUDIBLE ALARMS

During a utility failure or fault operation, the EL-Inverter a emits beeping sound for warning. In back-up mode, the alarm can be silenced by pushing the “MAIN CONTROL ON/OFF BUTTON” button. However, the warning of low battery will still sound urging user that load will be lost.

TEST BUTTON

If the EL-Inverter is in normal operation it is supplying the load by the incoming utility supply. In the case of a failure in this supply, the output is connected to the static inverter output. This transfer operation is performed internally by the control logic of the Inverter. The operation of the EL-Inverter can be controlled externally; the unit can be forced to supply the output by the Inverter and batteries. This can be achieved by pressing the TEST Button or opening the external test loop.

Note: When the equipment is switched into the Test mode, the red “TEST ON” LED will be lit. The TEST Button or the external test loop can be used for testing the machine’s operation and performance; it can also be used to maintain the EL-Inverter’s loads.
WARNING: When the TEST Button or the external test loop has been used, it is important that it is switched off so the EL-Inverter can return to a standby operation and the batteries are recharged

INSTALLATION

Do not stack the pallets.

The cabinet is bolted to the shipping pallet and packed in a cardboard sleeve that is designed to protect it from mechanical and environmental damage. Further protection is provided by wrapping the equipment with a plastic sheet. Before you accept the shipment ensure that the received package(s) correspond to the description shown in the delivery documentation and carefully examine the packing containers for signs of physical damage

REPORTING DAMAGE

Claims for shipping damage must be filed immediately when found, and the carrier must be informed of ALL claims within seven days of receipt of the equipment. If the equipment is to be stored for longer than seven days before it is installed, you should unpack it and inspect it for signs of internal damage before you put it into storage. Note that some optional equipment packages might be shipped inside the cabinet and these too should be checked for damage. If the equipment is damaged you should store the packing materials for further investigation

STORAGE

If you plan to store the EL100XA prior to its installation it should be kept upright (preferably in its original shipping packaging) in a clean, dry environment with a temperature between -25°C to +60°C and RH <93%. If the storage period is likely to exceed seven days the packaging should be removed and the cabinet inspected for shipping damage before it is placed into storage. If there is no apparent damage you should refit the packaging or cover the cabinet with a dust-cover to prevent the ingress of dust and dirt. Batteries that are intended for external rack-mounting will be shipped in a separate package and should be stored under the environmental conditions stipulated above.

UNPACKING INSTRUCTIONS

WARNING: The cabinet, battery cabinet (optional) and battery packages are heavy and may tip during unpacking unless the unpacking instructions are not followed closely.

If the shipment is received in good order then unpack the EL100XA cabinet as follows:

When the cabinet is placed in its final location, install the 4kVA power modules and secure them in place.

Install a blanking plate to the front of any shelves that have no power module fitted.

Batteries

CAUTION: The system batteries must ALWAYS be installed by the commissioning engineer. The batteries are shipped in a separate package and should remain in their packing until required by the Kohler Uninterruptible Power Ltd. service engineer when the system is commissioned. Battery life depends very much on the ambient temperature, and optimum battery life will be obtained if the batteries are stored and operated at a temperature of 20°C.
WARNING: If the system is delivered without batteries, Kohler Uninterruptible Power Ltd. will not accept responsibility for any damage or equipment malfunctioning caused by the incorrect storage, installation or connection of batteries carried out by third parties.

ENVIRONMENTAL CONSIDERATIONS

A certain amount of pre-planning will help provide a trouble-free installation process. You should consider the following guidelines when planning the installation location and operating environment.

The route to the installation location must allow the equipment to be transported in an upright position.

The floor at the proposed installation site and en-route from the off-loading point must be able to\ safely support the weight of the cabinet/battery equipment, plus fork lift or trolley jack during transit.
The cabinet requires sufficient front and rear clearance to enable cooling airflow, as described below.
All maintenance, servicing and user operation can be carried out from the front of the cabinet, but rear access is required for connecting the AC and DC power cables.

An ambient temperature of 20°C is necessary to achieve the recommended battery life span.
The cooling air entering the cabinet must not exceed +40°C.
The floor material should be non-flammable and strong enough to support the heavy load.

In summary, the system should be installed in a location where:
- a) Humidity (< 93%) and temperature is ideally 20°C.
- b) Fire protection standards are respected.
- c) Cabling can be performed easily.
- d) A minimum 800mm front accessibility is available for service or periodic maintenance.
- e) Adequate cooling air flow is available.
- f) The air conditioning system can provide a sufficient amount of air cooling to keep the room at, or below, the maximum desired temperature (where used).
- g) No dust or corrosive/explosive gases are present.
- h) The location is vibration free.

CLEARANCES

Cooling air enters from the right hand side of the cabinet and exhausts from the left hand side.

a) You should provide a minimum of 800mm clearance at the front of the cabinet to allow the power module(s) to be removed/installed.

b) You should provide a minimum of 250mm at both sides.
c) The cabinet does not require any rear clearance for cooling purposes so it can be installed immediately to the wall.

CABLE CONSIDERATIONS

It is the customer’s responsibility to design and install the EL100XA supply and distribution circuits and provide all the external fuses, switchgear and cables required to connect the cabinet’s AC INPUT and SI
OUTPUT supplies. The information provided in this section should assist you in the planning and preparation of the power cabling. The AC INPUT terminals should be connected to a utility mains LV-switchgear panel and protected by a circuit breaker or fused isolator. Similarly, the SI OUTPUT terminals should be connected to the load equipment via a suitably protected load distribution panel. The Maximum recommended output circuit breakers sizes tested as per EN50171 are specified in the following table.

INRUSH CURRENT

Special Consideration should be taken when installing luminaires with very high inrush characteristics. The Inrush Current of LED Luminaires is determined by the driver (s) and is not proportional to the luminaire wattage or running current, LED luminaire inrush currents can be as high as 400 times the running current for a very short period of time. Further information regarding LED inrush currents can be found by accessing the “LIA Technical Statement LIA TS35” from the LIA website (www.thelia.org.uk). The table below provides some details regarding the maximum recommended inrush currents for luminaires:

If higher inrush levels are expected Kohler Uninterruptible Power Ltd can provide Inrush Current Limiter for LED lighting Drivers. Rated at maximum 16A continuous power they can be installed within lighting distribution panels.

CABLE SPECIFICATION

All cables and protective devices must be selected in accordance with national and local regulations and codes of practice (e.g. BS7671:2008 or relevant country standards) to suit the maximum capacity of the system, as shown in the table below.
NOTE: If you install a system containing fewer than six power modules with a view to increasing the system capacity it at a later date as your load increases, you should consider using cables rated for the maximum system rating at the outset. This will simplify the future update process and avoid having to shut-down the system at a later date to replace the power cables. ALL power modules have internal fuse protection

ELECTRICAL PLANNING

All electrical power connections are made to terminals located on the rear of the cabinet near the top. Gland plates are fitted to the top and bottom of the cabinet immediately above the power terminals to allow either top or bottom cable entry. If the cabinet is to be installed in a location with restricted rear access, you should ensure that suitably-contained power cables are available before the cabinet is moved to its intended final position

CABLING PROCEDURE

SAFETY NOTES

Please ensure you read and understand the following safety notes before you begin the electrical installation.

All the operations detailed in this section must be performed or supervised by a qualified, authorized electrician.
Once the electrical installation is completed the initial system start-up must be performed by a qualified engineer, trained and authorized by Uninterruptible Power Supplies Ltd..
Do not connect the system if there is water or moisture present.
When working on the input power cables, you must ensure that the AC INPUT supply is isolated at the main switchgear panel and, where possible, locked out. Warning notices should be posted where applicable to prevent the inadvertent operation of the LV supply isolator(s).

Battery Cables

The DC cabling for the battery system(s) must be completed by an Kohler Uninterruptible Power Ltd. engineer or one of its approved service agents. The customer installation team is only responsible for providing any necessary containment for the DC cables.
WARNING: Do not attempt to fit the batteries, complete the battery wiring, or close the battery isolator

BATTERY INSTALLATION

WARNING!!! Be careful while connecting batteries.
ATTENTION!!! Ensure the battery circuit breaker is in the “0” position before making the connection for the battery installation. The batteries associated with the EL-Inverter equipment are usually mounted on purpose-built battery shelves within the Chassis Cabinet. Sealed, maintenance-free batteries are normally used in this type of installation. Where battery racks are used, they should be sited and assembled in accordance with the battery manufacturer’s recommendations. In general, batteries require a well-ventilated, clean and dry environment at reasonable temperatures to obtain efficient battery operation. In general, a minimum space of 10 mm must be left on all vertical sides of the battery block. A minimum clearance of 10 mm should be allowed between the cell surface and any walls. A clearance ofa minimum 100 mm should be allowed between the top of the cells and the underside of the shelf above (this is necessary for monitoring and servicing the cells). All metal racks and cabinets must be earthed. All live cell connections must be shrouded.

Unpack each battery and check its terminal voltage. If any battery has a terminal voltage less than 12.5VDC, it must be charged before continuing.
Please check the battery connecting hardware and continue the following in respect to the battery cable kit drawing.
Ensure the insulating membrane is in place on each shelf.
Please locate suitable number of batteries at each shelf.
Start locating the batteries from the bottom to the top of the chassis.
Be careful about the connection between the battery’s polarities.
After interconnecting the batteries, connect the (+) and (-) poles to the battery DC MCB1 & 2 inside the EL-Inverter. Be careful to connect the batteries correctly and ensure the following:
- a. Check the voltage and polarity of the battery at the input of DCMCB 1 & 2 before it is closed.
- b. Close MCB3 before starting the EL-Inverter.

EL1005 BATTERY INSTALLATION

The EL100XA 1005 system can only contain 1 x string of 4 x 12Volt batteries on one shelf. The drawings below show typical layouts of the shelf inside the unit.

MAINTENANCE INSTRUCTIONS

The EL100XA does not contain any user-serviceable parts, so day-to-day maintenance requirements are minimal other than to ensure that the operating environment is kept cool and dust free. A clean operating environment will help maximise the useful working life and reliability of both the EL100XA and its batteries.

EMERGENCY LIGHTING MAINTENANCE

The PowerpPro EL100XA system should be maintained as per the regulations set out in EN50172 Standards

Log Book Should be kept on-site indicating all testing/inspection reports as detailed within the standard
Daily – Indicators of central power supply should be visually inspected for operation
Monthly – All luminaires and exit signs should be put into test and transferred to the central battery supply. The Central Battery system should be put into test and all luminaires checked for operation. After return to normal operation, the central battery system should be checked for normal operation.
Annually – The specific Monthly test should be conducted for the full duration of the system.

After restart the charging of the batteries should be fully checked for operation. The certificate/Test sheet should be recorded within the logbook.

SCHEDULED MAINTENANCE

It is essential that the EL100XA cabinet and batteries receive regular preventative maintenance to maximize both the useful working life and system reliability. When the system is commissioned, the commissioning engineer will leave a service record book with the customer that will be used to log its full-service history. We recommend that the system is maintained every Twelve months (visit frequency should be increased dependent on environmental conditions) by a Kohler Uninterruptible Power Ltd. Trained engineer, or approved service agent, who will complete the following:

Preventative maintenance inspection

Preventative maintenance inspections form an integral part of all Extended Warranty Agreements (maintenance contracts) offered by Kohler Uninterruptible Power Ltd.

During a preventative maintenance inspection, the engineer will check and validate:

site environmental conditions
the integrity ofthe electrical installation
cooling airflow
load characteristics
integrity of alarm and monitoring systems
operation of all installed options.

Battery maintenance and testing

The battery installation should be inspected on a regular basis, not exceeding 12 months. Traditional VLRA battery testing and maintenance consists of:

checking and recording the open-circuit battery voltage
verifying that the float charging voltage is correct
inspecting all battery terminals and connections for corrosion
inspecting all batteries for cracks, leaks or swelling
checking the integrity of the inter-cell connections
removing any materials and cleaning around the equipment
carry out a full battery check.

TROUBLESHOOTING

EL-Inverter contains complicated electronic control circuits. In order to locate any fault occurring circuits, advanced knowledge about the circuitry and its operation principles must be known. The aim of this section is to give the knowledge required at the first intervention. There is no practical way to locate any possible fault. Most of the faults do not cause a loss of supply to the loads. Generally, the EL-Inverter operates normally or switches into by-pass mode. But in order to determine any change in load or the system the parameters must be recorded regularly as mentioned previously. Generally, the output voltage can deviate 2% from the predefined values. If values differ more than this percentage then reasons must be investigated.

The following general structure must be systematically followed while trying to indicate the error:

Fault determination: First step is to record the messages, indicator panel LEDs, operating parameter values and last status of switches. This must be done before attempting to press any button.
Fixing interventions: After recording all indications, check the meaning of the fault and alarm messages using “The operator control indicator panel”. If anything relates, follow the related procedure.

COMMUNICATION

INTRODUCTION

The EL100XA system offers a range of interfaces that can be connected to external facilities management and monitoring systems. Many of these options are factory-fitted and must be requested at the time of order.

SYSTEM TEST (ST) – INCLUDED

The System Test (ST) facility is used to test the EL100XA operation on battery power and terminals must be normally closed. In this case, if the connection between the ST terminals goes open-circuit it turns off the rectifier and the load is operated from the inverter using the standby battery power. The ST function can be connected to a local or remote operating device (switch). The ST terminals send an internal 24V signal internally and therefore no voltage can be applied to the circuit. When using a remote test facility they should be connected using a screened cable with 1 pair (0.5 mm²) and a maximum length of 100m.

Note: If an external ST circuit is not required, a link must be fitted to the ST terminals.

DRY PORT CONTACTS – INCLUDED

The EL100XA provides three hard-wired ‘system status’ outputs that can be used to drive remote signaling and/or monitoring facilities. This output are switched by volt-free relay contacts and are normally open (closed on activation). The contacts are rated for 110VAC (0.5A) or 24VDC.

As shown in Figure 7.2, the four switched alarm outputs are:

Mains Failure
Common alarm
Battery voltage low
Battery test active

Connections to these terminals are via the 5 provided Din-Rail terminals

SNMP CARD – OPTIONAL EXTRA

Simple Network Management Protocol (SNMP) is a worldwide, standardized communication protocol that can be used to monitor any network-connected device via a simple control language and display the results in an application running within a standard web browser. An SNMP card is factory fitted option, designed to house a Modem/Ethernet SNMP adapter card, is located on top of the power module if fitted. The SNMP adapter card contains an RJ-45 Ethernet connector which allows the EL100XA to be connected to a network using a standard CAT-5 network cable. Once connected, the system management software agent that is preinstalled in the SNMP adapter monitors the EL100XA operation and outputs its data in SNMP format to the connected network. The communication exchanged between the EL100XA and the network enables event/alarm emails, server shutdown (with optional licenses) and other tasks to be performed. It can also be integrated with BMS software over a local area network (LAN) for SNMP or Modbus information over IP. The SNMP adaptor requires a PC with terminal connections and for normal operation at least one Ethernet connection.
