Grounding terminal
Each machine has a standard PE terminal.
Note:
Do not use an asymmetrically constructed motor cable. If there is a symmetrically constructed grounding
conductor in the motor cable in addition to the conductive shield, connect the grounding conductor to the
grounding terminal at the inverter and motor ends.
Route the motor cable, input power cable and control cables separately.
Terminal “T” is not used with single-phase input inverters.
3.2.3 Wiring of terminals in main circuit
1. Connect the grounding conductor of the input power cable with the grounding terminal of the inverter (
PE
) by
360
degree grounding technique. Connect the incoming supply to
R/L1, S/L2
and
T
terminals and fasten.
2. Strip the motor cable and connect the shield to the grounding terminal of the inverter by
360
degree grounding
technique. Connect the motor to
U
,
V
and
W
terminals on drive and fasten.
3. Connect the optional brake resistor with a shielded cable to the designated position by the same procedures in
the previous step.
4. Secure the cables outside the inverter mechanically.
