Use Stage Safety Grade Precautions
At wiring
•
Wiring must be performed only by qualied personnel under instructions
described in this manual. Failure to comply may result in unexpected accidents.
•
A circuit breaker must be used to isolate the power supply and the equipment.
Failure to comply may result in a re.
•
Ensure that the power supply is cut off before wiring. Failure to comply may result
in electric shock.
•
Ground the equipment properly according to the requirements. Failure to comply
may result in electric shock.
•
Never connect the power cables to the output terminals U, V, W of the AC drive.
Pay attention to the marks of the wiring terminals and ensure correct wiring.
Failure to comply will result in equipment damage.
•
Never connect the braking resistor between the (+) and (-) terminals of the DC
bus. Failure to comply may result in a re.
•
Use cables with dimensions recommended in the manual. Failure to comply may
result in accidents.
•
Use a shielded cable for the encoder, and ensure that the shield is reliably
grounded.
Before
power-on
•
Check that the following requirements are met:
The voltage class of the power supply is consistent with the rated voltage class of
the AC drive.
The input terminals R, S, T and the output terminals U, V, W are properly
connected.
No short-circuit exists in the peripheral circuit.
The wiring is secured.
Failure to comply may result in equipment damage.
•
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 may result in accidents.
•
Cover the AC drive properly before power-on to prevent electric shock.
•
All peripheral devices must be connected properly under the instructions
described in this manual. Failure to comply may result in accidents.
After
power-on
•
Do not open the cover after power-on. Failure to comply may result in electric
shock.
•
Do not touch any I/O terminal of the AC drive. Failure to comply may result in
electric shock.
•
Prevent personal injury during motor rotation if motor auto-tuning is required.
Failure to comply may result in accidents.
•
Do not change the factory parameters of the AC drive to prevent equipment
damage.
