Battery Mounting
With power removed from the equipment, drill four #29 (0.136") (3.45mm) holes in the panel mounting surface, and
tap for #8-32 threads, according to the hole pattern shown in the following figure. Use care to keep metal chips
from falling into other equipment. Securely attach the Auxiliary Battery Module to the panel mounting surface using
four #8-32 x ½" (M4x0.7x12mm) flat head machine screws.

CPU Battery Low Indication
The IC693ACC302 Auxiliary Battery module will not reliably provide the CPU with a battery low indication. User logic
should not rely on any of the battery status bits when using this battery.

Diagnostics
This unit is not user-serviceable. The unit has a built-in 1-Amp fuse that will open if the unit is subjected to a short
circuit or severe overload condition. This fuse is sealed inside the battery pack and is not replaceable.
To test the unit if you suspect that the fuse has opened, turn off PLC power, unplug the battery unit, and carefully
check the battery cable connector pins for presence of voltage with a volt meter. If voltage is present, the fuse is
not open. If no voltage is present, the internal fuse has probably opened and the unit will have to be replaced. Only
perform this check in a non-hazardous environment.
