Precautions
During
running
CAUTION
•
Check that the following requirements are met:
- The voltage class of the power supply is consistent with the
rated voltage class of the controller.
- 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 controller.
•
For synchronous motor, ensure that motor auto-tuning is
performed successfully. Perform trial running before resuming
the steel rope so as to make the motor run properly.
•
Do not perform the voltage resistance test on any part of the
controller because such test has been done in the factory.
Failure to comply will result in accidents.
•
Do not touch the rotating part of the motor during the motor
auto-tuning or running. Failure to comply will result in accidents.
•
Do not change the default settings of the controller. Failure to
comply may result in damage to the controller.
•
Avoid objects falling into the controller when it is running.
Failure to comply will result in damage to the controller.
•
Do not start/stop the controller by turning on or off the contactor.
Failure to comply will result in damage to the controller.
During
maintenance
DANGER
•
Do not repair or maintain the controller at power-on. Failure to
comply will result in electric shock.
•
Repair or maintain the controller when its voltage is lower than
36 VAC, about 10 minutes after the controller is powered off.
Otherwise, the residual voltage in the capacitor may result in
personal injury.
• Do not allow unqualified personnel to repair or maintain the
controller. Failure to comply will result in personal injury or
damage to the controller.
•
Set the parameters again after the controller is replaced. All the
pluggable components must be plugged or removed only after
power-off.
1.2 General Precautions
1. Requirement on the residual current device (RCD)
The controller generates high leakage current during running, which flows through the
protective earthing conductor. Thus install a type- B RCD at primary side of the power
supply. When selecting the RCD, you should consider the transient and steady-state
leakage current to ground that may be generated at startup and during running of the
