3.8 Backup Batteries
The control panel battery charge capacity is 7.0 to 35.0 AH. Use 12V batteries of the same AH rating. Determine
the correct AH rating as per your current load calculation (see 3.6.2).
Wire batteries in series to produce a 24-volt equivalent. Do not parallel batteries to increase the AH rating.
Batteries larger than 18 AH (not to exceed 35 AH) use the RBB Remote Battery Box. It is recommended that you
replace the batteries every five years. The following steps and diagram explain how to connect the batteries.
1. Connect the black wire to the negative (-) side of battery #1.
2. Connect the jumper wire provided (P/N 140694) from the positive (+) side of battery #1 to the negative side
of battery #2.
3. Connect the red wire to the positive (+) side of battery #2
