AC Line Input Connections:
Incoming AC line supply connections should be wired into terminals:
- L ‘Live’ & N ’Neutral’ on single phase products (20G-12-…)
- L1, L2 & L3 on three phase products (20G-3x-… & 20G-4x-…)
On three phase products, phase rotation is not critical.
AC Motor Output Connections:
Output motor supply connections should be wired into terminals U, V & W.
Phase rotation is critical to ensure consistency between the inverter motor control direction and motor shaft
rotation.
The motor direction can be inverted electronically by setting the ‘IM Wiring’ parameter (0182) to ‘TRUE’.
This swaps output phases V & W in the drive firmware. Refer to ‘Chapter 9: Basic Drive Operation’.
Potential Earth (PE) Connections:
Connect both the inverter incoming supply earth cable and motor earth cable to the inverter PE terminals.
DC Dynamic Brake Output Connections:
Where a Dynamic Brake Resistor (DBR) is required for an inverter application, connect the resistor across
terminals DC+ & DBR.
