Inverter Installation And Wiring; Matters Needing Attention For Installation - HNC HV10 Series User Manual

II. Inverter Installation and Wiring

2.1 Matters needing attention for Installation

1. Before wiring, please confirm that the input power supply has been cut off.
Danger of electric shock and fire.
2. Ask electrical engineering professionals for wiring operations.
Danger of electric shock and fire.
3. The grounding terminal must be grounded reliably.
Danger of electric shock and fire.
4. After the emergency stop terminal is connected, check whether its action is effective.
There is a danger of injury. (the wiring responsibility shall be borne by the user)
5. Do not touch the output terminal directly. The output terminal of the frequency inverter is
directly connected with the motor. Do not short circuit between output terminals.
Danger of electric shock and short circuit.
6. Before power-on, be sure to install the terminal cover. When removing the cover, always
disconnect the power supply first.
There is danger of electric shock!
7. Cut off the power supply, and wait for 5 to 8 minutes for the remaining power in the machine to
be basically discharged before carrying out inspection and maintenance.
Danger of residual voltage on electrolytic capacitor.
8. Do not carry out inspection and maintenance for non-professional technicians.
There is danger of electric shock!
1. Please confirm whether the power supply voltage of incoming line is consistent with the rated
input voltage of frequency inverter.
There is danger of injury and fire.
2. Please connect the braking resistor or braking unit according to the wiring diagram.
Danger of fire.
3. It is best to use a screwdriver and wrench with specified torque to fasten the terminals.
Danger of fire.
4. Do not connect the input power cord to the output U, V and W terminals.
Voltage applied to the output terminal will cause internal damage of the frequency inverter
5. Do not remove the front panel cover, only the terminal cover needs to be removed when
wiring.
May cause internal damage to the inverter.
