Terminal wire arrangement
INVERTER INTRODUCTION 49
Note: 1.Do not connect power wire to motor terminals (U/T1) - (V/T2) - (W/T3) on inverter, otherwise it will cause
damage.
2. Do not add phase capacitor, surge absorber or magnetic contactor on the output of the inverter.

3. Do not use the "magnetic contactor" or "no fuse switch" to start and stop the motor.
4. Please do grounding for the inverter and motor to avoid electric shock.
5. For specifications of no-fuse breaker and magnetic contactor, please refer to section 3.6.2.
6. If the distance between the inverter and motor is long, please use thick wires, make sure wire voltage drop is
under 2V (wire length below 500 meters).
7. Use "insulation crimp sleeve " for power supply side and load side connection.
8. After cutting off terminal power, high voltage still exist between (+/P) and (-/N) in short period of time. Within 10
minutes, do not touch terminals to avoid electric shock.
3.7.3 Ground
For safety and to reduce noise, the grounding of the inverter must be well grounded.
To avoid electric shocks
and fire accident, the external metal ground wire of the equipment should be short and thick, and should be connected
to specific grounding terminals on the inverter.
If several inverters are placed together, all inverters must be
connected to the common ground.
Please refer to the following diagrams and ensure that no loop is formed between
grounding terminals.
