1.3 Power Connection Checks
No
Description
Check
17.
Check all power connections are assembled and tightened correctly; check power
terminations have been fully insulated
18.
Perform a point-to-point wiring check as per installation wiring diagram to determine
the transformer is correctly connected and phased.
19.
Open MCCB (if fitted) and F4/F5 20A auxiliary fuses. Using a simple ohm-meter check
there is no short circuit PCS100 AVC-40 input to input (L1–L2, L2–L3, L3–L1) (load
disconnected and input circuit breaker open).
20.
Perform this step only with the 400/480V PCS100 AVC-40 (these are the models that
do not have an autotransformer) fitted with a MCCB (rectifier circuit breaker). Open
the rectifier feed MCCB and F4/F5 20A auxiliary in the MC Enclosure. Check for
continuity L1-L2, L2-L3 and L3-L1 on the downstream side (rectifier side) of the MCCB.
This must show an open circuit. Close F4/F5 fuses.
21.
Using the resistance range of a multimeter, check there is no short circuit at PCS100
AVC-40 input to ground (L1-G, L2-G, L3-G).
22.
Using the resistance range of a multimeter, check there is no short circuit at rectifier
supply input to ground (L1R-G, L2R-G, L3R-G.).
