Caution: When the DC breaker is tripped off because of over current or short
circuit, must wait after 30min to turn on it again, otherwise may cause the breaker
damage.
Power On Button: Generally when it is at ON state, you can’t turn off it during
normal running condition.
Danger: Ensure Power On Switch is turned on before waking up the battery.
Otherwise it will affect automatic checking process and cause danger.
Danger: DO NOT turn off the “ Power On Switch” during normal running condition,
only in emergency case it could be turned off directly. Otherwise will cause this
battery string current surge by another battery strings.

3 Installation and Configuration
3.1 Environmental Requirement
3.1.1 Cleanliness
The battery system has high voltage connectors. The environment condition will affect the
isolation performance of the system.
Before installation and system power on, the dust and iron scurf must be removed to keep a
clean environment. And the environment must have certain anti-dust ability.
Dust and humidity condition shall be periodic checked during the system continuous operation.
3.1.2 Temperature
Tower system working temperature range: 0℃~50℃; Optimum temperature: 18℃~30℃;
Caution: Out of the working temperature range will cause the battery system over / low
temperature alarm or protection which may lead to the cycle life reduction.
3.1.3 Cooling System
It is essential to equip a cooling system to keep the battery system in a relevant temperature
range.
Caution: Out of the working temperature range will cause the battery system over / low
temperature alarm or protection which may lead to the cycle life reduction.
3.1.4 Heating System
It is essential to equip a heating system to keep the battery system in a relevant temperature
range. If the environment is lower than 0 ℃,the system may be shut down for protection
purpose. It is necessary to open the heating system at first.
Caution: Out of the working temperature range will cause the battery system over / low
temperature alarm or protection which may lead to the cycle life reduction.
3.1.5 Fire-extinguisher System
The room must be 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.
3.1.6 Grounding System
Make sure the grounding point for battery system is stable and reliable before the battery
installation. 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
3.2 Installation clearance requirements
Please note that the battery should be installed with a minimum safe clearance from the
surrounding equipment or battery. Please refer to the minimum clearance diagram below.

3.4 Tools
The following tools are required to install the battery pack:
NOTE:
Use properly insulated tools to prevent accidental electric shock or short circuits.
If insulated tools are not available, cover the entire exposed metal surfaces with available
insulated alternatives, except their tip, with electrical tape.
3.5 Safety Gear
It is recommended to wear the following safety gear when dealing with the battery pack
3.6 Unpacking inspection
When the equipment arrives at the installation site, loading and unloading should
be performed according to the rules and regulations, to prevent from being
exposed under sunlight. Battery should not be installed in direct sunlight. Please
refer to Section 3.3
Before unpacking, the total number of packages shall be indicated according to the
shipping list attached to each package, and the case shall be checked for good
condition.
In the process of unpacking, handle with care and protect the surface coating of the
object.
Open the package, the installation personnel should read the technical documents,
verify the list, according to the configuration table and packing list, ensure objects
