Control Panel Installation Battery Power
4.5.1 RBB Accessory Cabinet
The RBB accessory cabinet can be used when your backup battery requirements use batteries that are too large to fit into the main control
panel cabinet. The RBB cabinet holds up to the 35 AH batteries. RBB dimensions are 16" W x 10" H x 6" D (40.64 cm W x 25.4 cm H x
15.24 cm D).
Installing the RBB Accessory Cabinet and Batteries
To properly install the accessory cabinet and backup batteries, follow these steps:
To properly install the accessory cabinet and backup batteries, follow these steps:
1. Mount the accessory cabinet. See Figure 4.7 for the four cabinet mounting holes.
• If mounting onto drywall the accessory cabinet must be mounted onto 3/4-inch plywood. This is necessary because the weight of the
batteries inside the accessory cabinet could cause the cabinet to pull away from the drywall.
• When mounting on concrete, especially when moisture is expected, attach a piece of 3/4-inch plywood to the concrete surface and
then attach the RBB cabinet to the plywood.
• If using the battery cable extenders provided (P/N 140643), mount the RBB cabinet no more than 18" away from the main control
panel cabinet. This will ensure that the battery cables reach the battery terminals.
2. Connect the main control panel battery cables to the battery cable extenders as shown in Figure 4.8.
3. Run extended battery cable from control panel cabinet through conduit to RBB cabinet as shown below.
4. Connect battery leads to the backup battery terminals. Observe the proper polarity to prevent damage to the batteries or the control
panel.
