battery lead to Terminal 5, and then to the positive (+) side of the battery.
High Current Arcs Possible
The positive (red) battery lead and Terminal 5 can create high current arcs if shorted to other terminals or the
enclosure. Use caution when working with the positive lead and Terminal 5. Always disconnect the positive
(red) lead from the battery before removing it from Terminal 5.
CAUTION
The Battery Terminals and Wires are NOT Power Limited. A ¼ in. (6.4 mm) spacing must be maintained
between the battery terminals, battery wiring and all other wiring. Battery wiring may not share the same
conduit, conduit fittings or conduit knock-outs with other wiring. See Figure 5.

Replacing the Battery
Radionics recommends battery replacement every 3 to 5 years under normal use. Exceeding the maximum output
ratings, or installing the transformer in an outlet that is routinely switched off, causes heavy discharges. Routine
heavy discharges can lead to premature battery failure. Record the date of installation directly on the battery.
D8132 boosts battery backup: Adding a D8132 Battery Charger Module supports additional batteries of up to 36
Ah capacity if required.
The D8132 Battery Charger Module can be used to connect two additional batteries for a total of four. The panel
plus any connected D8132 Modules and AUX power supplies must be on the same AC circuit so they will
discharge evenly if AC power fails. The number of D8132 Modules is determined by the number of available outlets
on the same circuit. See
Standby Battery and Current Rating Chart in the D9412G/D7412G Approved Applications
Compliance Guide for battery standby time calculations.
Note:
In applications where the supervision of two batteries is required by the AHJ, a D113 Battery Supervision
Module must be used.
