If you are uncertain about any of the requirements, recom- mendations, or safety procedures described in this manual, contact LG Chem imme- diately for advice and clarification.
Saftey NOTE To use rechargeable batteries, you are required to comply with standard AS 4086.2 in Australia and VDE-AR-E2510-2 in Germany. 1.1 Symbols on product labels The nameplate is attached to the left side of the battery pack, and the warning label is attached to the top.
Saftey The battery pack is heavy enough to cause severe injury. The battery pack may leak corrosive electrolyte. The battery pack may explode. The battery pack should not be disposed of with household waste at the end of its working life. The battery pack should be disposed of at a proper facility for environmen- tally safe recycling.
• Do not use cleaning solvents to clean the battery pack. 1.3 Response to emergency situations The RESU battery pack comprises multiple batteries that are designed to prevent haz- ards resulting from failures. However, LG Chem cannot guarantee their absolute safety. Leaking batteries If the battery pack leaks electrolyte, avoid contact with the leaking liquid or gas.
Damaged batteries are dangerous and must be handled with extreme caution. They are not fit for use and may pose a danger to people or property. If the battery pack seems to be damaged, pack it in its original container, and then return it to LG Chem or your distributor.
CAUTION Damaged batteries may leak electrolyte or produce flammable gas. If you suspect such damage, immediately contact LG Chem for advice and information. 1.4 Qualified installers This manual and the tasks and procedures described herein are intended for use by skilled workers only.

Commissioning 7.1 Status indicators Battery pack There are four LED indicators on the front of the battery packs to show its operating status. ON: This indicator stays on while the battery pack is supplied with power for opera- tion. Charging: This stays on while the battery pack is charging. Discharging: This stays on while the battery pack is discharging.
If two battery packs are installed, both must be turned on at an interval of less than 30 seconds. 2. Make sure that the ON indicator is lit. If it stays off, do not use the battery pack. Contact LG Chem or your distributor. 3. Turn on the inverter. NOTE If communication with the inverter is not established within 10 minutes after the battery pack is turned on, the circuit breaker automatically trips.
Troubleshooting Check the indicators on the front to determine the state of the battery pack. A warning state is triggered when a condition, such as with voltage or temperature, is beyond design limitations. The battery pack’s BMS periodically reports its operating state to the inverter.
Firmware Update It is possible to update the BMS firmware. Use a memory card to update it. A new firmware may be available from LG Chem website or your distributor. Prepare a memory card with these properties: • The capacity of the memory card must not be greater than 32 GB.
Page 46
Firmware Update 5. Press and hold the update button beside the memory card slot for more than 3 seconds. 6. The LED indicators flash in cycles until the firmware update is complete. Only the ON in- dicator is lit when the firmware update is suc- cessful.
