Inverter Connections
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.
