1.1.7 During Repair
1.2 Precautions
1.2.1 Motor Insulation Inspection
1.2.2 Thermal Protection of the Motor
When the motor is used for the rst time, or when the motor is reused after being kept, or when
periodical inspection is performed, it shall conduct motor insulation inspection so as to avoid
damaging the inverter because of the insulation failure of the motor windings. The motor wires
must be disconnected from the inverter during the insulation inspection. It is recommended to
use the 500V megameter, and the insulating resistance measured shall be at least 5MΩ.
If the ratings of the motor does not match those of the inverter, especially when the rated
1.1.6 During the operation:
Danger
Do not touch the fan or discharge resistor to sense the temperature.
Otherwise, you may get burnt!
Detection of signals during the operation shall only be conducted by
quali ed technician. Otherwise, personal injury or equipment damage may
be caused!
Caution
During the operation of the inverter, keep items from falling into the
equipment. Otherwise, it may damage the equipment!
Do not start and shut down the inverter by connecting and disconnecting the
contactor. Otherwise, it may damage the equipment!
Danger
Do not repair and maintain the equipment with power connection. Otherwise
there will be danger of electric shock!
be sure to conduct repair and maintenance after the charge LED indictor of
the inverter is OFF. Otherwise, the residual charge on the capacitor may
cause personal injury!
The inverter shall be repaired and maintained only by the quali ed person
who has received professional training. Otherwise, it may cause personal
injury or equipment damage!
Carry out parameter setting after replacing the inverter, all the plug-ins must
be plug and play when power outage.
