Battery Power Control Panel Installation
4.3 Battery Power
The batteries must be sealed lead acid type. Before connecting the batteries to the FACP, make certain that the interconnect cable between the
batteries is not
connected. Do not connect the battery jumper cable until the System is completely installed. Observe polarity when connect-
ing the batteries.
The control panel battery charge capacity is 7.0 to 35 AH. The main control cabinet can house batteries up to 7 AH, larger capacity batteries
can be housed in a Remote Battery Box (P/N RBB). See Section 4.3.1 for details. Use 12V batteries of the same AH rating. Determine the
correct AH rating as per your current load calculation (see Section 3.7).
Maximum battery charging current 3.1 Amps.
Wire batteries in series to produce a 24-volt equivalent. Do not parallel batteries to increase the AH rating.
The following steps and diagram explain how to connect the batteries.
1. Connect the black wire from the control panel negative (–) battery terminal to the negative (–) side of Battery #2.
2. Connect the jumper wire provided (P/N 140694) from the positive (+) side of Battery #2 to the (–) negative side of Battery #1.
3. Connect the red wire from the control panel positive (+) terminal to the positive (+) side of Battery #1.
