1.2.3 Response to Emergency Situations
The Product includes internal fault mechanisms designed to prevent failures and subsequent risk hazards. However, LG Energy Solution cannot guarantee safety performance of the Product is ever exposed to abuse, damage or negligence.
- If a user happens to be exposed to the internal materials of the battery cell due to damage on the outer casing, the following actions are recommended. In case of inhalation: Leave the contaminated area immediately and seek medical attention.
In case of contact with eyes: Rinse eyes with running water for 15 minutes and seek medical attention.
In case of contact with skin: Wash the contacted area with soap thoroughly and seek medical attention.
In case of ingestion: Induce vomiting and seek medical attention.
If a fire breaks out at the location where the battery pack is installed, perform the following countermeasures.
• Utilize fire-extinguishing media
A respirator is not required during normal operation.
Use an FM-200 or CO2 extinguisher for battery fires.
Use an ABC fire extinguisher if the fire is not from the battery and has not yet spread to it.
• Follow proper fire-fighting instructions
- If a fire occurs when charging batteries, provided it is safe to do so, disconnect the battery pack circuit breaker to shut off the power charge.
- If the battery pack is not on fire yet, extinguish the fire before the battery pack catches fire preferably with water.
- If the battery pack is on fire, do not try to extinguish it, and evacuate people from the premises immediately.
WARNING
There may be a possible explosion when batteries are heated above 150^ C. When a battery pack is burning, it will leak poisonous gases. Do not approach it.
• Effective ways to deal with accidents
On land: Place the damaged battery into a segregated place and call your local fire department or service engineer.
In water: Stay out of the water and do not touch anything if any part of the battery, inverter, or wiring is submerged.
Do not use the submerged battery again. Contact your service engineer for assistance.

4.2 Damping On the Bottom Book
5 Troubleshooting
5.1 Troubleshooting Overview
Checks the LED indicators on the front to determine the state of the battery pack. A fault state is triggered when certain conditions like voltage or temperature are beyond design limitations. The battery pack's HMS periodically reports its operating state to the inverter.
When the battery pack falls outside of prescribed limits, it enters a fault state. When a fault is reported, the inverter immediately terminates operation.
Use the monitoring software on the inverters to identify what caused the fault state. The possible warning messages see as follows:
- Bartery Overvoltage
- Battery Undervillage
- Barley Over Temperature
- Battery Under Temperature
• Battery Discharge Overcurrent
- Battery Charge Overcurrent
- Bartery Overcharge Power Limit
- Battery Overdischarge Power Limit
• BMS Internal Error
- External Communication Error
• Internal Communication Force
• Battery Cell Deviation Voltage
- Bartery Pack Undervoltage
• Battery Urgent Undervoltage
The fault state is cleared when the battery pack resumes normal operation. If battery pack is not working correctly and the issue persists, contact a qualified staff, installer or LG Energy Solution regional contact service point.
NOTE
For serious warnings, if no proper conective action is taken by the inverter, the battery pack's circuit breaker will automatically trip to protect itself.
CAUTION
If the battery pack or the inverter indicates FAULT or fails to operate, contact LG Energy Solution regional contact point or your distributor immediately.
