3.3 System Working Environments Checking
3.3.1 Cleaning
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.
3.3.2 Temperature
Force-L2 system working temperature range: 0℃~50℃; Optimum temperature: 18℃~28℃.
Caution: Force-L2 system is out-door design. But please avoid frost or direct sunlight. Out of the
working temperature range will cause the battery system over / low temperature alarm or
protection which further lead to the cycle life reduction. According to the environment, the
cooling system or heating system should be installed if it is necessary.
3.3.3 Fire-extinguisher System
It will be better equipped with fire-extinguisher system for safety purpose.
The fire system needs to be regularly checked to be in normal condition. Refer to the using and
maintenance requirements please follow local fire equipment guidance.
3.3.4 Grounding System
Before the battery installation must make sure the grounding point of the basement is stable and
reliable. If the battery system is installed in an independent equipment cabin (e.g. container),
must make sure the grounding of the cabin is stable and reliable.
The resistance of the grounding system must ≤100mΩ
3.4 Handling and placement
Single battery module is 35kg. If without handling tools must have more than 2 men to handling
with it.
3.4.1 Handling and placement of the base
The base is light, single person can handle with it.
3.4.2 Selection of installation sites
A. Force-L2 system working temperature range: 0℃~50℃; Optimum temperature: 18℃~28℃.
Do not place the battery system in direct sun light. It is suggested to build sunshade
equipment. In could area the heating system is required.
B. Force-L2 system must not be immersed in water. Cannot be placed the battery base in rain or
other water sources. As a suggestion, the base’s height should >300mm above the ground.
C. The base’s weight capacity should support the weight of whole battery system (119~260kg).
