4.2.2Installing the Battery
Place the battery upright in the base of the enclosure. Locate the red and black leads supplied in the literature pack. Connect the black battery lead to Terminal 4, and then to the negative
WARNING
CAUTION
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.
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

4.2.3Replacing the Battery
Bosch Security Systems 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 27 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 Section 4.1 Current Rating Chart for Standby Battery Calculations in the D7212G Approved Applications Compliance Guide (P/N: 4998138560) 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. | ||
