3. Remove the subbase or wallplate from the wall and drill
two 3/16 inch holes in the wall (if drywall) as marked.
For firmer material such as plaster or wood, drill two
7/32 inch holes. Gently tap anchors (provided) into the
drilled holes until flush with the wall.
4. Position the subbase or wallplate over the holes, pulling
wires through the wiring opening.
5. Loosely insert the mounting screws into the holes.
6. Tighten mounting screws.

WIRING SUBBASE OR WALLPLATE

All wiring must comply with local electrical codes and
ordinances. Follow equipment manufacturer wiring
instructions when available. Refer to Fig. 19 through 32 for
typical hookups. A letter code is located near each terminal
for identification. Refer to Table 6 for terminal designations.
CAUTION
Disconnect power before wiring to prevent electrical
shock or equipment damage.
