Motor to the inverter to a ground terminal
To connect a motor and the inverter plus link them to a ground terminal, use the following
procedure.
1)
Connect terminals T1(U), T2(V) and T3(W) of the inverter's main circuit terminal block to terminals
T1{U), T2(V), and T3(W) of the motor.
2)
Connect a ground line to terminal G/E or the inverter. The ground line should meet the class
specifications required of your system's configurations.
3)
When using a motor with a rating smaller than the range of electronic thermal activation level,
or when multiple motors are simultaneously run, install an overload relay that matches the
motor, between the inverter and the motor, as shown in Table 8.1.
• The grounding connection should conform to class 3 specifications.
Before you connect any wiring, be sure to turn the power supply switch on the distribution
board OFF.
