Protective earthing (PE) terminal for safe protection; each device
must be proper grounded.
Note:
Do not use asymmetrical motor cables. If there is a symmetrical grounding conductor in
the motor cable besides the conductive shielded layer, ground the grounding conductor on
the VFD end and motor end.
Route the motor cable, input power cable and control cables separately.
3.1.6 Wiring the main circuit terminals
Step 1 Connect the grounding line of the input power cable to the PE terminal of the VFD,
connect the 3PH input cable to the R, S and T terminals of the VFD, and tighten up.
Step 2 Connect the grounding line of the motor cable to the PE terminal of the VFD, connect
the 3PH cable of the motor to the U1/U2, V1/V2, and W1/W2 terminals of the VFD, and
tighten up.
Step 3 If allowed, fix all the cables at the outside of the VFD mechanically.
