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 (

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 (
