Replacing Batteries
If a battery or string of batteries fails, becomes damaged, or wears out its life, you can replace the battery or string as de-
scribed below. Replacing batteries does not impact cabinet service, provided that an AC power failure does not occur during
the replacement process. Clearfield recommends connecting an external generator to the cabinet while performing battery
maintenance to ensure service continuity in the event of an AC outage.
To replace batteries
At the rectifier shelf, switch the battery breaker to OFF.
Remove the battery compartment door. See Operating Cabinet Doors for instructions.
To remove an old 60 Ah battery string:
a.
If present, remove the seismic protection bracket from the front of the batteries.
b.
Remove the lower retainer bracket from the frame of the battery compartment.
c.
Disconnect the battery power cables from the power supply terminals.
d.
Slide the batteries out of the battery compartment.
e.
Remove the protective covers from the battery terminals.
f.
Remove the red and black battery power cables from the terminals at each end of the string.
g.
Remove the jumper straps from between the terminals of the batteries in the string.
Install the new batteries into the battery tray. See Installing Batteries for instructions.
