WARNING!
Read and understand the battery safety instructions in “Product Safety Information”.
CAUTION!
Make sure all the replacement batteries are of the same type and rating. Failure to do so could result in
improper charging and damage to the batteries.
The Alpha FXM cannot provide backup battery power while the batteries are being replaced. If the line becomes
unqualified while the batteries are being replaced, the Alpha FXM shuts down and no power is provided to the
load.
Procedure
1. The Alpha FXM must be in the Line state. If it isn’t, wait until the line is qualified before proceeding.
2. Switch the Alpha FXM into the Bypass State by doing one of the following:
a. From the Alpha FXM control panel, navigate to the
UPS Control Menu > BYPASS
. Press the
SELECT
button once OFF is flashing. Press the
SCROLL
button once ON is flashing. Press the
SELECT
button once ON is displayed continuously, indicating that the Alpha FXM has been
switched into the Bypass state.
b. From the Alpha UPS Monitor main screen, go to the
UPS Maintenance > Unit Configuration
screen. Switch on the
Bypass Mode
by clicking the
ON
button and then the
Update Configuration
button. The Alpha FXM responds by displaying a “Bypass State” alarm. This is normal and does not
indicate a problem. It will clear itself when the Bypass state is subsequently disabled.
3. Switch off the battery circuit breaker.
4. Replace the batteries.
5. Switch on the battery circuit breaker.
6. Switch the Alpha FXM out of the Bypass state by switching the
