Step 2: Mount the U-Bracket

Mount the U-bracket (Item A) to a wall or ceiling using the appropriate holes (Figure 5). Use fasteners (not included) that are suitable for the construction mate- rial of the wall or ceiling. See dimension diagrams for mounting hole patterns and dimensions.

Step 3: Mount the Zx3 to the U-Brackets

Slide the Zx3 into the U-bracket by aligning the M8 cap screws with the front slots of the U-bracket (Figure 6). The weight of the Zx3 will pull the top M8 cap screw into the recess of the front slot of the U-bracket (wall mount/vertical orientation only). Rotate the Zx3 to the desired orientation (Figure 7), and install the two M8 washers (Item F), two M8 lock washers (Item G), and two M8 cap screws (Item E), using the threaded hole that aligns with the rear slot. Tighten the four M8 cap screws (Figure 8).
