Inhalation
Evacuate the contaminated area, and seek medical attention immediately. 1.4.3 Eye contact
Rinse eyes with flowing water for 15 minutes, and seek medical attention immediately.

Skin contact
Wash the affected area thoroughly with soap and water, and seek medical attention immediately.

Ingestion
Induce vomiting, and seek medical attention immediately.

Fire
In case there is a fire, always have an ABC or carbon dioxide extinguisher.

Note: The battery pack may catch fire when heated above 150°C.
If a fire breaks out where the battery pack is installed, do these actions:

• Extinguish the fire before the battery pack catches fire.
• If it is impossible to extinguish the fire but you have time, move the battery pack to a safe area before it catches fire.
• If the battery pack has caught fire, do not try to extinguish the fire. Evacuate people immediately.

Note: If the battery catches fire, it will produce noxious and poisonous gases. Do not approach.

Wet batteries
If the battery pack is wet or submerged in water, do not try to access it. Contact DLG or your distributor for technical assistance.

Damaged batteries

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.

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 current or temperature, is beyond design limitations. The battery pack’s BMS periodically reports its operating state to the inverter. when the battery pack falls outside prescribed limits, it enters a warning state. When a warning is reported, the inverter immediately stops operation. use the monitoring software on the inverter to identify what caused the warning. The possible warning messages are as follows:

• Battery Over Voltage
• Battery Under Voltage
• Battery Over Temperature
• Battery Under Temperature
• Battery Discharge Over Current
• Battery Charge Over Current

The abnormal state is cleared when the battery pack recovers normal operation.
