Wall Mounting, Wood Surface
When mounting the IND780 to a wooden wall or similar surface, use four #12 screws of at least 1
1/4" (30 mm) length, each with a flat washer of minimum 1/2" (12 mm) diameter.
Install the screw and washer, leaving sufficient gap to accommodate the slotted hole in the bracket
– see Figure 2-10 and Figure 2-12.
Periodically inspect the terminal to insure that it is securely anchored to the wall. If not, remove the
terminal and retighten the mounting anchor bolts.
2.9.1.3.5.
Positioning Terminal on Fasteners
Place the holes in the terminal brackets over the fasteners, and slide the terminal down firmly so
that each fastener and washer engages the slots in the bracket (see Figure 2-10).
For wallboard or drywall mounting, after engaging the brackets pull them away from the wall until
the toggle nuts are felt to contact the inside of the wall. If necessary, unmount the terminal and
tighten the bolts slightly. Figure 2-15 shows the relationship between bracket, hardware and wall.
