15. Connect the lugs to the input terminals on the back
of the panel, as shown in Figure 5.
16.
Tighten the lugs to 140 in.-lb (~15½ N•m).
17.
Make sure the TPA and GMT fuse positions are
either empty or contain dummy fuses (phoney,
inoperative, all-plastic slugs). If necessary, pull
out the TPA carrier about an inch from its holder
to disengage the TPA fuse, as shown in Figure 6.
18.
Enable the fuse or breaker at the PDU (400A max.)
to turn on Feed A to Side A of the panel and then
check the voltage and polarity at input connectors
of the panel. Also, check that:
•
Power
A
LED on the front of the panel turns on
(green).
•
Power
B
LED must turn red.
19. With
A
LED green (normal operation) — but with
B
LED off (failure operation)— test the power-fail
relay and contacts at
A PWR
alarm terminals on
the rear of the panel:
• Expect continuity (0Ω) between Terminals
C
and
NC
.
• Expect an open circuit (∞Ω) between Terminals
C
and
NO
.
20.
Also, test the fuse alarm relay contacts at the
FUSE alarm terminals on the rear of the panel.
• Expect continuity (0Ω) between Terminals
C
and
NC
.
• Expect an open circuit (00Ω) between Terminals
C
and
NO
.
