Check if wire connections are loose.
Check if cables are aged/damaged.
Check if cable insulating ribbon drops.
Check if cable terminal screw loose, any overheat sign.
Check if ground connection is well.
Appropriate protective measures should be taken while maintaining, such as insulated
gloves, shoes, and anti-noise ear plugs.
Life is priceless. Make sure no one would get hurt first.
In case of a deep discharge, the battery must be charged to a SOC rate of 30% to 50%
if the entire system is static (ie the battery has not been charged for two weeks or
more).
Please contact us in time if there are any conditions that could not be explained in the
manual.

Please turn off the parallel connection
mode and check if the configuration is
correct and the communication cables
are normal.
(Every six months to one year)
Check if the cable connections are loose.
Check whether the cables are aged / damaged.
Check whether the cable tie of the cable has fallen off.
Check if the cable terminal screws are loose and the terminal position has any signs of
overheating.
Check whether the management system of the system equipment, monitoring system
and other related equipment are invalid or damaged.
Check that the grounding of the equipment is good and the grounding resistance is
less than 10 ohms.
After the equipment are out of operation, please pay attention to following notes while
maintaining :
Related safety standards and specifications should be followed in operation and
maintenance.
Disconnect all the electrical connections so that the equipment would not be powered
on.
Wait at least 5 minutes after disconnection, so that the residual voltage of the
capacitors drops to a safe voltage. Use a multimeter to make sure that the equipment
is completely discharged.
The equipment should be repaired by professional staff only and it is strictly forbidden
for maintenance staff to open equipment modules on their own.
(Every six months)
Carefully observe whether the battery system equipment is ineffective or damaged;
When the system is running, listen to any part of the system for abnormal noise;
Check whether the voltage, temperature and other parameters of the battery and other
equipment parameters are normal during system operation;
(Every six months to one year, depending on the site environment and dust content, etc.)
Ensure that the ground is clean and tidy, keep the maintenance access route unblocked,
and ensure that the warning and guiding signs are clear and intact.
Monitor the temperature of the battery module and clean the battery module if
necessary.
