Installation

DANGER: HAZARD OF FIRE, ELECTRIC SHOCK, EXPLOSION, BURN, OR ARC FLASH

• This battery shall be installed and serviced only by qualified personnel.
• Always wear proper PPE (safety glasses and clothing) when working on the Li-ion battery and follow safe electrical work practices according to local codes.
• Do not wear metallic items such as watches or bracelets when working on the battery. Use insulated tools to prevent accidental short circuit.
• Do not install the Li-ion battery module adjacent to any heat source. Keep away from sources of ignition.
• Do not install or operate any of the system devices in a compartment containing flammable materials or in locations that require ignition-protected equipment.
• Do not use in vital, medical, or life-support applications.

Failure to follow these instructions will result in death or serious injury.

1. Check the battery, the cable-mounted keyable plug (Figure 1), and the battery cable (if included) for visible damage including cracks, dents, chips, and deformations.
2. Select a location for the battery that is stable, clean, cool, dry, and well-ventilated.
3. Mount the battery with either the top label or the side label pointing up. Keep the battery away from all heat sources.
4. Orient the devices so that the cables avoid sharp bends. Follow the bending radius recommendation (Figure 3). This applies to all DC cables.
5. Disassemble the cable-mounted keyable plug (Figure 1) and set them (the top, terminals, and boot) aside.

NOTE: Installation and maintenance shall only be performed by qualified personnel as defined in Important Safety Information above.

6. Make sure the battery is turned off. If the LED on the battery is lit, press and hold the button for ten (10) seconds until the LED turns off. Also ensure all other DC sources have been powered off and disconnected, if possible.
7. Attach using a 5/16" (or 3/8") lug, the negative (-) battery cable to the negative (-) battery terminal of the cable-mounted keyable plug. Review Figure 2 for proper routing including feeding the cables through the boot and stacking the terminal hardware. Tighten the bolt to 60±3 in-lb (or 6.7±0.35 N-m).
8. Install your DC-rated circuit protection device (Figure 2) in line with the positive battery cables.

BATTERY DAMAGE: Check the cable polarity before making the final DC connection to avoid damage due to reverse polarity. Do not connect multiple batteries in series to avoid damaging the battery. See Figure 4. You may connect multiple batteries in parallel. See Figure 4.

Failure to follow these instructions can result in battery and equipment damage and may void the warranty.

9. Attach the protected positive (+) battery cable to the positive (+) battery terminal of the cable-mounted keyable plug. Review Figure 2 for proper routing including feeding the cables through the boot and stacking the terminal hardware. Tighten the bolt to 60±3 in-lb (or 6.7±0.35 N-m).
10. Reassemble the cable-mounted keyable plug by encapsulating the key assembly with the top and boot.
11. Attach the cable-mounted keyable plug to the battery terminals by turning the key lever clockwise.

DANGER: HAZARD OF FIRE, ELECTRIC SHOCK, EXPLOSION, BURN, OR ARC FLASH

• No user-serviceable parts. Do not attempt to open or dismantle the Li-ion battery. If the battery module is damaged, do not touch the corrosive electrolyte or powder, and consult your dealer.
• When the battery module is damaged, it can release harmful gases. Ensure the surrounding environment is well-ventilated.
• In case battery content comes in contact with skin or eyes, immediately flush the affected area with large amount of clean water and seek medical help.
• In case of fire, use only a Class ABC (dry chemical) or CO2 type fire extinguisher. Water can be a dangerous extinguishing medium for energized equipment because of the risk of electric shock.
• Dispose of Li-ion batteries through a local recycling center. Do not mix batteries with other wastes. Contact your local recycling center for proper disposal information.
• Do not crush, puncture, drop, disassemble, or dispose of in fire.

Failure to follow these instructions will result in death or serious injury.

WARNING: HAZARD OF FIRE, ELECTRIC SHOCK, EXPLOSION, AND PERSONAL INJURY

• Do not expose the Li-ion battery to rain, snow, or liquids of any type. Products are designed for indoor use only.
• Do not step or stand on the battery module enclosure.
• Always use proper lifting techniques when handling the battery module. Battery is heavy.
• Do not charge the battery in ambient temperature below freezing.
• Do not disconnect the battery while it is being charged.

Failure to follow these instructions can result in death or serious injury.

RISK OF EQUIPMENT DAMAGE

• Do not allow the battery to be depleted.

NOTICE: Charge the battery module with an approved charger. Contact Xantrex for details. Do not charge the battery above the recommended voltage.

Failure to follow these instructions can result in damage to equipment and may void the warranty.

12. Turn on the battery by pressing and holding the Power button for one (1) second. The battery takes approximately 40 seconds to boot up and the contactor to close.
13. Verify that the voltage on the DC bus is approximately 12VDC (nominal).

Optional: Connect the 12-pin connector cable and route the remote connectors as required.

Table 1 Pin reference guide

3. Operation

Power push button for ON | OFF | MAINTENANCE. The push button is a multi-function button that must be held down for specified durations to complete each action.

• Press the push button for more than one (1) second from either OFF or MAINTENANCE mode to turn the battery ON.
• Press and hold the push button for 3-5 seconds during ON mode and this will put the battery to MAINTENANCE mode. This disconnects the cells and reduces the idle power consumption of the battery.
• Press and hold the push button for more than ten (10) seconds during either ON or MAINTENANCE mode and the battery will turn OFF.

See the Owner's guide (document number: 975-1044-01-01) for information on Interpreting Ring LED Patterns on the Battery.

NOTE: The battery LED shall blink once per second for the first three seconds while held down, then transition to four times per second.

Troubleshooting

When planning to remove the battery pack from a live system, place the battery in MAINTENANCE mode before disconnecting the Rebling connector.

The Xantrex Battery has event or error states that are available through the Xantrex App via Bluetooth. Alternatively, the Power button's ring LED shows flashing patterns which correspond to an event or error state. See the Owner's guide (document number: 975-1044-01-01) online by scanning the QR code at the last section of this guide.

If you connect with the Xantrex BMS via Bluetooth and using the Xantrex App on your smart device, you can find out more detail about the battery state including diagnosing and solving detected error events.

Storage and Maintenance Instructions for Long Durations

1. Reduce the battery state-of-charge (SoC) to 50% ±10% which is approximately 13.2V for a 12V battery.
2. Turn off the battery by pressing and holding the Power pushbutton for ten (10) seconds.
3. Keep the battery in an environment according to Battery Storage Guidelines.
4. Every six months maintain the battery by charging it to 100% SoC, then discharging the battery to low voltage cutoff (LVC) level, then charging it back to 50% ±10% SoC.

RISK OF BATTERY DAMAGE: Do not charge the battery in ambient temperature below freezing.

Failure to follow these instructions can result in damage to the battery and may void the warranty.

NOTE: Keep the cables between batteries and ground cables the same lengths for optimal performance and to ensure equal discharging and charging.

Battery Maintenance Guideline

The Xantrex Lithium-ion Batteries system is designed to require the least amount of maintenance as possible. The battery and internal BMS are contained in a sealed device and do not require disassembly for maintenance reasons.

In general, to properly maintain the battery, follow the storage guidelines in the previous sections.

If the battery/ies are in regular use, then it is recommended that the battery/ies be fully charged a minimum of once per two weeks in order for the BMS to recalibrate its State of Charge (SoC) setting. This process also ensures that the SoC meter maintains its accuracy.

* For long term duration storage the battery should be kept in a particular charged state such as, 13.2V, ~50% SoC, and stored at the recommended storage specifications shown above.

Storage Instructions for Short Durations

1. Fully charge the battery.
2. Turn off the battery by pressing and holding the Power pushbutton for ten (10) seconds.
3. Keep the battery in an environment according to Battery Storage Guidelines.
