• There are no flammable or explosive materials nearby
• The ambience is shady and cool, keep away from heat as well as direct sunlight
• The temperature and humidity stay at a constant level
• There is minimal dust and dirt in the area
• There is no corrosive gases present, including ammonia and acid vapor
• The ambient temperature is with the range from 0℃ to 55℃ and the optimal ambient temperature is between 15℃ and 35℃

Notice
The L02 battery is rated at IP65 and thus can be installed outdoors as well as indoors. However, if installed outdoors, do not expose the battery to directly sunlight and moisture
Notice
If the ambient temperature is beyond the operating range, the battery pack will stop operating to protect itself. The optimal temperature range for the battery pack to operate is from 15℃ to 35℃. Frequent exposure to harsh temperatures may deteriorate the performance and lifetime of the battery module.

Battery Installation

1. Floor-mounting Installation
   -Remove the back screws and bracket-Move the battery to proper position
2. Wall-mounting Installation
   -Mark the position of the holes Bracket for wall-mounting
   -Screw the expansion bolts -Drill four holes with a φ8 drill bit
   -Depth: at least 40mm -Match the battery with the bracket-Hammer the expansion bolts into the holes-Lock the joint between hanging board and wall bracket with M4 screws

Notice The distance between the bottom of the battery pack and floor shall not exceed 300mm

Ground cable connection

-Crimping Ground terminal
Crimp terminals according to the distance between battery and external ground point

Communication cable connection

-Crimping CAN plug terminal

Take out CAN plug and RJ45 terminal of inverter| Crimp terminals according to the distance between battery and inverter

Insert CAN plug into battery CAN port and Insert RJ45 terminal into inverter COM port

Caution:
