If the battery pack leaks electrolyte, avoid contact with the leaking liquid or gas. Electrolyte
is corrosive and contact may cause skin irritation and chemical burns. If one is exposed to the
leaked substance, do these actions:
Inhalation : Evacuate the contaminated area, and seek medical attention immediately.
Eye contact : Rinse eyes with owing water for 15 minutes, and seek medical attention
immediately.
Skin contact : Wash the aected area thoroughly with soap and water, and seek medical
attention immediately.
Ingestion: Induce vomiting, and seek medical attention immediately.
1.3.2 Fire
In case of a re, make sure that an ABC or carbon dioxide extinguisher is
nearby.
WARNING
The battery pack may catch re when heated above 150°C.
If a re breaks out where the battery pack is installed, do these actions:
1. Extinguish the re before the battery pack catches re.
2. If the battery pack has caught re, do not try to extinguish the re. Evacuate people
immediately.
WARNING
If the battery catches re, it will produce noxious and poisonous gases.
Do not approach.
1.3.3 Wet batteries
If the battery pack is wet or submerged in water, do not try to access it. Contact LG Chem or
your distributor for technical assistance.

3 Installation Prerequisites
3.1 Installation materials
These installation materials shall be prepared by installers.
• Charging cable
• Network cable
• Ground wire
• RJ45 plug
• Silicone sealant or putty
NOTE
Make sure that the cross-sectional area of charging cables is 33 to 50 mm2.
3.2 Installation location
Make sure that the installation location meets the following conditions:
• The building is designed to withstand earthquakes.
• The location is far away from the sea, to avoid salt water and humidity.
• The oor is at and level.
• There are no ammable or explosive materials nearby.
• The optimal ambient temperature is between 15 and 30°C.

1) White with an orange stripe
2) Orange
3) White with a green stripe
4) Blue
5) White with a blue stripe
6) Green
7) White with a brown stripe
8) Brown

5. Bring the sorted wires together, and trim them to about 1.4 cm in length.
6. Hold the RJ45 plug with the copper contacts facing up, and insert the wires into the plug,
making sure that they stay aligned and each color goes into its appropriate channel.
7. Put the plug into a cable crimper and squeeze the handles thoroughly.
8. If available, use a LAN cable tester to see if the cable is faulty.
Repeat these steps for the other end of the cable.
