CDE360 Vector Control AC Drive Chapter 1 Safety Information and Precautions
WARNING
Do not drop wire end or screw into the AC drive. Failure to comply will result in the damage
to the AC drive.
Install the AC drive in places free of vibration and direct sunlight.
When two AC drives are laid in the same cabinet, please arrange the installation positions
properly to ensure the cooling effect.
At wiring
DANGER
Wiring must be performed only by qualified personnel under instructions described in this
user manual.
Failure to comply may result in unexpected accidents.
A circuit breaker must be used to isolate the power supply and the AC drive. Failure to
comply may result in a fire.
Ensure that the power supply is cut off before wiring. Failure to comply may result in the
electric shock.
Tie the AC drive to ground properly by standard (earthing resistance less than 10 Ohms).
Failure to comply may result in the electric shock.
Do not control the run or stop of the AC drive by turning on or off the input power supply.
DANGER
Pay attention to marks of the wiring terminals. Never connect the power cables to the output
terminals (U,V,W) of the AC drive. Failure to comply will result in damage to the AC drive.
Ensure that the wiring conforms to EMC requirements and the safety standard of the region.
Please refer to proposals of the user manual when considering the diameter of the wire.
Failure to comply will result in accidents.
Never connect the braking resistor between DC bus terminals (+) and (-).Failure to comply
will result in a fire.
Before power-on
WARNING
Check that following requirements are met:
The voltage class of the power supply is consistent with the rated one of the AC drive.
The input terminals (R, S, T) and output terminals (U, V, W) are properly connected.
No short-circuit exists in the peripheral circuit.
The wiring is secured.
Failure to comply will result in the damage to the AC drive.
Do not perform the voltage resistance test on any part of the AC drive because such test has
been done in the factory. Failure to comply will result in accidents.
