3.5.9 Wiring Precautions
Main circuit wiring:
1. Do not connect the power supply wires to the “motor connecting terminal
U/T1-V/T2-W/T3” or the inverter may be damaged.
2. Please do not mount phase advance capacitor, surge absorbers and electromagnetic
contactors at the output terminal of the inverter.
3. Please do not use “electromagnetic contactors” or “no-fuse switches” with an online power
to start or stop the motor.
4. Please ensure that the case of the inverter and of the motor are grounded to avoid
personnel electric shock.
5. To select appropriate diameter of the main wires and specification of the pressing
connection terminal, the no-fuse switch and the electromagnetic contactor, please refer to
Section 3.7. If the inverter is far away from the motor, please employ a wire with larger
diameter to ensure the voltage drop along the wire is within 2V. (The total length of the
wire shall not exceed 500 m)
