Maintenance and Inspection
Please carry out regular maintenance and inspection on the drive and motor for safe use.
Notes for maintenance and inspection
1) The operator should first cut off the power supply. Do not approach the motor and the machine
it drives when wrong actions occur during power-on.
2) For a short period of time after the power supply is cut off, the internal circuit still maintains a
high voltage charging state. Before inspection, the power supply must be cut off; wait for 10
minutes, and make sure that the charging light is completely off.
3) If it is necessary to test the insulation resistance of the drive, all connections to the drive must
be cut off. Insulation resistance test on the drive connected with wires or a motor will damage
the device.
4) Do not use gasoline, diluents, acidic or alkaline detergents to clean the device, otherwise
discoloration or damage to the case may occur.
