Adjusting the rectifier and the dc distribution shelf 10-15
AccessNode Series 800A Outside Plant Cabinet Installation 323-3001-210 Issue 1.0
Procedure 10-3 (continued)
Adjusting equalize voltage
Action
Step Action
1 Hold the FLOAT/EQL momentary switch to EQL for local equalize and
measure the equalize voltage at the test points labeled V+ and V- on the
rectifier.
2 Adjust the EQL voltage using the EQL potentiometer clockwise to increase
the EQL voltage or counterclockwise to reduce the EQL voltage to -55.5 V dc
(see Table 10-6 on page 10-14).
Note:
Nortel Networks recommends setting the equalize voltage at
-55.5 V dc for the battery options listed. Other types of batteries may require
setting voltages at different levels.
3 Turn the ac circuit breaker on the rectifier to the OFF position.
4 Turn the dc circuit breaker on the rectifier to the OFF position.

CAUTION
Overvoltage damage to equipment hazard
Do NOT adjust the voltage above -56.0 V dc as damage to
the AccessNode equipment may result.
