Trouble Shooting
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, 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 for-bidden for
maintenance staff to open equipment modules 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.
➢
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 (e.g. 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.
