Wall Mounting the Total Access 908 BBU (1200641L1)

shows the BBU mounting dimensions for the Total Access 908 (template included with
Figure 7
BBU).
For a wallmount installation, the BBU installs on plywood (3/4-inch minimum) using two
#10 x 3/4-inch pan-head wood screws (customer provided). Install the BBU as follows:
Step
1 Determine the preferred unit layout to ensure cable plugs reach their designated sockets.
2 Ensuring a plumb measurement, mark where the pilot holes are to be drilled according to the
dimensions given in the documentation included with your shipment.
3 Drill the two pilot holes using a size 1/16-inch drill bit.
4 Screw in the top two pan-head screws that fit the keyhole openings. Let the head of each
screw protrude ~1/8 inch from the plywood to engage the keyhole slot.
5 Position the BBU and to hang on the screw heads. Allow the unit to slide down until the slot
end rests against the screws. Then fully tighten the #10 screws to secure the BBU to the
plywood.
6 Use cable ties as appropriate. The battery connection from the BBU should be directly
connected to the BBU port on the rear of the chassis.
