Power Wiring Connections

WARNING Isolate supply and ensure residual energy is discharged before wiring up the product.
For correct tightening torques and recommended wire sizes, refer to HA503711U001/U002 'Chapter 4: Installation
– Power Stack'.
Wiring Details – AC line fed 710 Stacks
Connect the incoming three phase supply cables into terminals L1, L2 & L3 respectively. Phase rotation is not
critical.
Likewise, connect the three phase motor cables into terminals U, V & W. Phase rotation is important to ensure
consistency between the inverter motor control direction and motor shaft rotation.
Connect both the incoming supply earth and motor earth to the inverter PE terminals.
L1
Where output ringcores are required when installing a C2 filter product:
1. Position the output ringcore in the cutout on the cabling bracket.
2. Pass the three motor supply conductors through the centre of the ringcore when connecting to the
inverter terminals U, V & W.
Note: The earth connection does not pass through the centre of the ringcore.
3. The cable clamps supplied with the cabling bracket should be used to clamp down on the exposed cable
screen, providing a 360° screen termination point.
Wiring Details – DC link fed 740 Stacks
Connect the DC supply cables into terminals DC+ & DC- respectively. It is important not to transpose these
connections.
Connect the three phase motor cables into terminals U, V & W. Phase rotation is important to ensure consistency
between the inverter control direction and motor shaft rotation.
When wiring an inverter for use as an AFE, terminals U, V & W are used to connect to the three phase mains
supply.
Earth both the inverter and motor earth (or incoming supply for an AFE application) to the inverter PE terminals.
