Cover Screws
• 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.

Note: Figure 3 is an example of how the wire connections can
be routed. However, any other cabinet knock-outs (on
either the main control panel or the RBB cabinet), that
are not previously being used may be utilized to connect
conduit between the two cabinets.
