Action
Ensure that all of the circuit breakers on the BIP are turned to the OFF
position.
Turn all circuit breakers on the dc distribution shelf to the ON position (see
Figure 10-5 on page 10-24).
Record the voltage displayed on the faceplate readout.
Confirm that the FA alarm indicator is extinguished.
Turn OFF CB1 on the dc distribution shelf to verify that the FA alarm LED
illuminates red.
Turn CB1 back ON to verify that the FA alarm LED extinguishes.
Turn OFF, then ON, each of the circuit breakers, one at a time, to verify that
the FA indicator illuminates and extinguishes with each breaker trip.
Turn all breakers back to the OFF position.
Turn ON the EQL switch on the dc distribution shelf to verify that the EQL
indicator illuminates yellow and that the voltage level displayed on the
faceplate display corresponds to the EQL level (-55.5 ± 0.1) set on the
rectifiers.
