4.2.2 Installation precautions
After connecting all the external wiring related to the maintenance control box with the maintenance control
box according to the wiring steps, the whole body is fixed on the wall.
When installing the expansion pipe, drilling is required. The depth of the hole is slightly longer than the
length of the expansion pipe (about 3-5mm), which is convenient for firm installation.
Keep the installation environment well ventilated, avoid installing in places with too high or too low
temperature and high humidity, keep away from water, flammable gas or corrosive agent and heat sources, and
avoid direct sunlight.
Avoid using in the environment with dust, volatile gas, corrosive gas or excessive salt. Do not place
inflammable and explosive materials around the battery system.
To minimize damage from accidental fires, fireproof materials should try to be used on the walls, ceilings and

14
floors of the room where the battery system is located, and portable dry powder fire extinguishers should be
provided.
4.2.3 System wiring criterion
The maintenance control box has positive and negative interface of battery, battery communication interface,
EMS communication interface, PCS communication interface and cascading interface. All interfaces are built-in. The
system wiring is strictly in accordance with the following requirements:
Power cables shall meet the requirements of 100VDC voltage, 80A continuous current and 25mm2wire
diameter.
All connectors must be safe and reliable to ensure that there are no loosening and virtual contact problems,
and the contact resistance is less than 20 mΩ. The connectors must have anti-corrosion, wear-resisting and
anti-seismic functions.
The copper busbar terminals at the end of power cables adopt SC25-6.
The parameters of bipolar bidirectional DC circuit breaker are rated voltage DC125V and rated current
DC100A. Its main function is to maintain and protect overcurrent.
All connections must meet the requirements of relevant national standards, and strictly prevent various forms
of arc discharge.
It is strictly forbidden to have any form of short circuit in the process of connection.
Operators are strictly forbidden to operate without wearing protective equipment.
All connections must be carried out under clear guidance, and any form of conjecture or vague attempt is not
allowed.
The key points of connection is that ensure correct and reliable connection (not loosening), good contact (no
contact resistance), no short circuit.
After the wiring harnesses are connected, they must be measured and confirmed point by point.
All connection points must ensure no contact with the external box or other parts, no short circuit.
If there are other uncertain factors, please consult professionals before implementation.
