NJ00675A-2 Dual Power Feed Unit Installation Procedure
Step 2: Locate the NE00675-31 G1 cable. This cable is approximately 18"
long and terminates in connector J117 on one end and in four 10
gauge lugs on the other. For the new DPFU, connect these lugs, using
the cable identification provided on the leads to the four screw termi-
nals on the barrier terminal strip (TB1) designated OUT for -48A, Rtn
A, -48B and Rtn B. Verify that the terminal strip screws are tightly fas-
tened.
Step 3:
the duct on the rear of the frame.
Step 4: Remove the plastic faceplate covers (TB1) from both units.
Step 5: On the defective DPFU, after verifying that both primaries are active
from the BDFB, disconnect, after opening the 45 or 50 Amp. breaker,
from the TB1 IN terminals the primary matching the Alarms LED (A or
B) that is lit. Reconnect that feed to the same terminals on the replac-
ing unit. Turn on the 45 or 50 Amp. breaker.
Step 6: With a VOM verify that -48VDC is present on both secondaries (-48A
and -48B OUT) of the replacement unit. Also verify that the green
Power LED is lit.
Step 7: Locate the unattached J117 connector from the replacing DPFU and
engage it to the unused P117B connector, after first removing its plas-
tic cover, (p/o NE00675-31, G2). At this point the replacing DPFUs
output is in parallel with the defective unit.
Step 8: On the defective DPFU remove the other primary (IN) and reconnect
to the In terminals of the replacing DPFU. Turn on the 45 or 50 Amp.
breaker.
Step 9: Disconnect the J117 connector from the P117A connector on the
NE00675-31, G2 cable assembly. Attach plastic connector insulator,
removed above from P117B, to P117A and dress this unused connec-
tor back into the frame.
