2.0 Battery Installation and Wiring
1. Load batteries into cabinet with the positive terminals (+) facing forward. Coat the hardware and battery terminals with
electrical contact lubricant and assemble the battery cables, PTS and hardware as shown in the illustrations below.
Torque hardware to 110 in-lbs (12.43 Nm).
2. The 12V batteries can be wired in parallel, up to four batteries total, to extend standby runtime. Other factors such as
cabinet size and company policies may depict the number of batteries utilized at a specific site. For sites with multiple
batteries, the individual battery voltages are not available in monitoring systems due to the parallel wiring connectivity.
3. With a MIDTRONICS
®
Conductance meter (Celltron
®
Essential, Celltron
®
Advanced or equivalent) measure the
conductance value (MHOS) of each battery and record for use in Section 5.2
Battery Configuration.
Also, record the
battery date code on the battery label for entry on the DATE SET screen.
Verify battery voltage, cable color, connection and polarity are correct before proceeding.
WARNING! ELECTRICAL HAZARD
A single 12Vdc battery.
Two 12Vdc batteries wired in parallel
provide 12Vdc output with double the Ah
capacity of each individual battery.
Three 12Vdc batteries wired in parallel provide
12Vdc output with triple the Ah capacity of each
individual battery.
