10-32 Adjusting the rectifier and the dc distribution shelf
AccessNode 323-3001-210 Issue 1.0
Procedure 10-10 (continued)
Adjusting dc distribution shelf low voltage disconnect return
Step Action
7 Slowly turn the LVDR potentiometer counterclockwise until the LVD LED
extinguishes.
8 Set the BYP/NORMAL switch to the NORMAL position.
9 Verify that the FLOAT voltage at the dc distribution shelf is within the
parameters set in Procedure 10-4 on page 10-16.
10 Ensure that all circuit breakers on the rectifier shelf are ON.
11 Ensure that all SENSE DIP switches on the dc distribution shelf are in the ON
position.
Note:
The SENSE DIP switch is in the ON position when the switch is pushed
away you.
12 Ensure that all circuit breakers on the dc distribution shelf are ON.
13 Ensure that all circuit breakers on the battery breaker panel are ON.
14 Turn the CU A and CU B circuit breakers on the BIP to the ON position.

CAUTION 2
DC voltage output 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.
