Earth (Ground) Checks - ABB PCS100 AVC-40 Manual

PCS100 AVC-40 Commissioning Checklist
23.
Check for continuity between injection transformer A2, B2, C2 and the PCS100 AVC-40
Inverter module AC terminals, U, V, W. This will require either removing the module covers,
or inserting a digital multi meter/duspol probe under the module front cover on the
PCS100 Inverter module.
NB: PCS100 Inverter modules on the PCS100 AVC-40 2B and larger machines are
always on the upper shelf of the Controller Enclosure.
24. Check there is no short circuit at inverter output to ground (Inv L1-G, Inv L2-G, Inv L3-
G).
25. Confirm the auxiliary supply cable is connected to the correct terminals located under
the rectifier shelf next to the L1R terminal of all Controller Enclosures. The label at the
bottom of each Controller Enclosure shows the correct connections depending on the
AVC system voltage.
