Installation

Run cables to the wall box. You can use any of the four openings with a surface

raceway. The raceway must be purchased separately.

Knockout Covers

The rear panel has four covers that can be removed to ll the unused openings. Two of

the four covers contains a nested knockout that can be removed to provide a smaller

opening to match the prole of smaller raceways or cables.

• The four openings (without covers) are 1.28" x 0.77" (33 mm x 20 mm).

• The nested knockouts are 0.7" x 0.5" (18 mm x 13 mm).

Install the covers by following these instructions.

1. Remove the cover, using small wire cutters to cut the plastic attaching the cover to

the wall box (1).

2. If required, use the wire cutters to remove the nested knockout.

3. Ensure the cover is in the correct orientation and slide it into place (2).

wall mounting holes table on the previous page).

4. If required, insert a grounding screw (not provided, see ﬁgure 2, D

and Eon the previous page).
