AccessNode Series 800A Outside Plant Cabinet Installation 323-3001-210 Issue 1.0
Adjusting the rectifier and the dc distribution shelf 10-15
Action
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.
CAUTION
Overvoltage damage to equipment hazard
Do NOT adjust the voltage above -56.0 V dc as damage to
the AccessNode equipment may result.
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.
Turn the ac circuit breaker on the rectifier to the OFF position.
Turn the dc circuit breaker on the rectifier to the OFF position.
