Maintenance Plan
Check if wire connection loose.
Check if cables aged/damaged.
Check if cable insulating ribbon drop.
Check if cable terminal screw loose, any overheat sign.
Check if ground connection is well.

.1.1
Operating Environment
(Every half year)
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;

.1.2
Equipment Cleaning
(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.

.1.3
Cable, Terminal and Equipment
Inspection
(Every six months to one year)
Check if the cable connection is loose.
Check whether the cable is aging or 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, monitor-ing system and other

Notes
After the equipment are out of operation, the following notes should be paid attention to 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 in case that the residual voltage of capacitors down to
safe voltage. Use a multimeter to ensure the equipment is completely uncharged.
The equipment should be repaired by professional staff and it is strictly for-bidden for maintenance
staff to open equipment on their own.
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.
The batteries need to be charged to 30%~50%SOC rate when the whole sys-tem is static (that is,
the batteries has not been charged for two weeks or longer) for a long time, in case of over discharge.
Please contact us in time if there are any conditions that could not be explained in the manual.
