3.3 System Working Environment Checking
3.3.1 Cleaning
Danger: Before installation and system power on, the dust and iron scurf must be
removed to keep a clean environment.
The system cannot be installed in desert area without an enclosure to prevent from sand.
Danger: Battery module has active DC power at terminals all the time. Be careful to
handle the modules.
3.3.2 Temperature
Force-H3 system working temperature range: -10℃~55℃; Optimum temperature: 18℃~28℃.
There are no mandatory ventilation requirements for battery module, but please avoid of
installation in confined area. The aeration shall avoid high salinity, humidity or temperature.
Caution: The IP rating of Force-H3 system is IP55. But please avoid frost or direct sunlight.
Out of the working temperature range will cause the battery system high / low
temperature alarm or protection which will further lead to the cycle life reduction.
According to the environment requirements, a cooling system or heating system should
be installed when necessary.
3.3.3 Fire-extinguisher System
Danger: Fire-extinguisher system must be equipped for safety purpose.
The fire system needs to be checked regularly to ensure a normal working status.

is stable and reliable. If the battery system is installed in an independent equipment
cabin (e.g. container), the grounding of the cabin must be stable and reliable.
The resistance of the grounding system must be ≤100mΩ
3.3.5 Clearance
Minimum clearance to heat source shall be more than 2 meters.
Minimum clearance between battery strings shall be more than 0.3 meters.
