2 Installation and wiring
Danger
◇ Ensure the power has been cut o before wiring.
Electric chock and re hazard.
◇ Ask electric engineering professionals to conduct wiring.
Electric chock and re hazard.
◇ Earth terminals must be reliable grounded.
(380V class: especially the third grounding)
Electric shock and re hazard.
◇ Check if its action is eective after emergency brake terminal is connected.
Injury risk (wiring responsibility should be beard by users).
◇ Do not touch output terminals directly. The output terminal is connected directly to
motor. There should be no short circuit between output terminals.
Electric shock and short circuit hazard.
◇ Install the terminal cover before power on, and ensure power o when dismantling the
terminal cover.
Electric shock hazard.
◇ Conduct check and maintenance after 5 ～ 8 minutes after power o when internal
residual electricity is discharged completely.
Hazard of residual voltage in electrolytic capacitor.
Cautlon
◇ Check if the voltage of power inlet wire agrees with rated input voltage of VFD.
Injury and re hazard.
◇ Connect brake resistor or brake unit according to wiring diagram.
Fire hazard.
◇ Choose screw driver and wrench with specied torque to fasten terminals.
Fire hazard.
◇ Do not connect the power input wire to output U, V, W terminals.
It will cause internal damage to VFD if load the voltage on output terminals.
◇ Do not dismantle the front panel cover, only the terminal cover needs to be dismantled
when wiring.
It may cause internal damage to VFD.
