Wall Mounting the BBUInstall the BBU as follows:Instructions for Wall Mounting the BBUStep Action1 Decide on a location for the BBU, keeping in mind that the cable plugs must be able to reachtheir designated sockets in the NetVanta unit.2 Prepare the mounting surface by attaching a board (typically plywood, 3/4-inch to 1-inch thick)to a wall stud using #6 to #10 (2.5-inch or greater in length) wood screws.Important! Mounting to a stud ensures stability. Using sheetrock anchors may not providesufficient long-term stability.3 Ensuring a plumb measurement, mark where the pilot holes are to be drilled according to thedimensions given in Figure 7 on page 30.4 Drill all four pilot holes using a size 1/16-inch drill bit.5 Screw two #10 x 3/4-inch pan-head screws into the top two previously drilled holes. Let thehead 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 supportuntil the lower two screws are fully inserted.6 With an assistant, lift the BBU and position to engage the screw heads into the top twokeyholes. Allow the unit to slide down until the slot end rests against the screws.7 Insert the two lower screws through the tabs and tighten securely.8 Use cable ties as appropriate. The battery connection from the BBU should be directlyconnected to the BATT port on the rear of the chassis.
