Figure 4-33 Main circuit terminal for 3PH 380V 400–500kW (-L3) models with output reactors (unit:
mm)
3PH AC input terminals, connecting to the grid
3PH AC output terminals, which connect to the motor in most cases
(+) and (-) can share the DC bus or connect to an external DC power
supply.
Grounding terminal for safe protection; each machine must carry two PE
terminals and proper grounding is required
Reserved, no braking function
Note:
 It is not recommended to 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 cable separately.
4.3.3 Wiring procedure for main circuit terminals
1. Connect the grounding line of the input power cable to the grounding terminal (PE) of the VFD,
and connect the 3PH input cable to R, S and T terminals and tighten up.
