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
