Adjusting the rectifier and the dc distribution shelf 10-3
AccessNode Series 800A Outside Plant Cabinet Installation 323-3001-210 Issue 1.0
CAUTION 2
Electrical shock hazard
Perform the steps in the order shown because the sequence
of turning the breakers on and off is critical.
CAUTION 3
Test the output dc voltage levels
If this is a new installation, the dc voltage output level from
each rectifier module must be tested and adjusted as per
Nortel Networks recommended float voltages for the battery
manufacturers listed below.
Eagle-Picher 6V: -54.70 ±0.10 V dc
Gates 12V: -55.00 ±0.10 V dc
Yuasa 12V: -54.00 ±0.10 V dc
Note: These ranges are subject to change without notice. For
other battery manufacturers, reference CAUTION 4.
CAUTION 4
DC voltage input requirements
The AccessNode input voltage specifications require that the
dc input to the BIP does not exceed -56.0 V dc. Battery float,
equalize and high voltage shutdown levels must be set below
this maximum regardless of the type of batteries installed.
CAUTION 5
Circuit breaker verification
Because there are circuit breakers on the ac service panel,
rectifier modules, and the battery breaker panel (BBP), use
caution before switching a circuit breaker. Make sure you are
switching the correct one.
CAUTION 6
Fire hazard
Remove all paper and any other combustible materials from
inside the cabinet before the cabinet is powered up. Failure
to comply with this warning could result in a fire.
