WARNING
• Do not drop wire end or screw into the AC drive. Failure to comply will result in
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, 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 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 be ore wiring. Failure to comply may result in
electric shock.
• Tie the AC drive to ground properly by standard. Failure to comply may result in
electric shock.
WARNING
• 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 damage to the AC drive.
• Never connect the braking resistor between the DC bus terminals (+) and (-).Failure
to comply may result in a fire.
• Use wire sizes recommended in the manual. Failure to comply may result in
accidents.
• Use a shielded cable for the encoder, and ensure that the shielding layer is reliably
grounded.
Before
power-on
DANGER
• 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 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 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.
