Wall Mounting the Total Access 912/916/924 BBU

Figure 6 shows the BBU mounting dimensions for the Total Access 912/916/924.
For a wallmount installation, the BBU installs on heavy plywood (3/4-inch minimum) using four
#10 x 3/4-inch pan-head wood screws. 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 all four 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 1/16 inch from the plywood to engage the keyhole slot.
Do not let the weight of the BBU rest on the two keyhole screws. Maintain support
until the lower two screws are fully inserted.
5 With an assistant, lift the BBU and position to engage the screw heads. Allow the unit to slide
down until the slot end rests against the screws.
6 Insert the two lower screws through the tabs and tighten securely.
7 Use cable ties as appropriate. The battery connection from the BBU should be directly
connected to the BATT port on the rear of the chassis.
