IMPORTANT: 3% line impedance MUST be provided for each module, and is assumed in the quoted input
current values. Failure to do so will severely curtail DC link capacitor lifetime and could result in damage to the
input bridge
51#
Input current quoted is for 380V supply at the stated motor power. Motor efficiency of 93% is assumed.
61#
Short circuit protection Semiconductor Fuses should be installed in the 3-phase supply to the drive module to
protect the input bridge. Circuit breakers or HRC fuses will not protect the input bridge.

Suitable for earth referenced (TN) and non earth referenced (IT) supplies.

The type 8 and 9 inverters have an integral main cooling fan. The type 10 inverter has a separate main cooling
fan which must be fitted to the bottom panel of the enclosure as shown in drawing HG463009G001 (Chapter 5)
with the 4 off M6 nuts provided. Refer to drawing HG463151D002 (Chapter 9) for fan wiring details (type 10
only).
The type 8, 9 and 10 each require an external single phase supply and fuse protection (motor start type) for the
main cooling fan.
