Installation
WALL MOUNTING
There are two methods for routing cables to the mount arm: through the rear opening or through the two conduit holes at the bottom of the
mount. Choose the method suitable for your installation.
PREPARING THE MOUNTING SURFACE
1. Mark the four fastener positions (4.75-inch bolt circle) on the mounting surface using the supplied conduit plate as a template.
2. Prepare the mounting surface with the appropriately sized fasteners (not supplied).
3. Attach the gasket (supplied) to the rear of wall mount arm.

ROUTING THE CABLES THROUGH THE REAR OF THE MOUNT ARM
1. Remove one or both knockout hole(s) on the conduit plate. For the FH-H Series, both holes must be used to properly separate high voltage
and ground wires from low voltage data wires.
2. Attach the conduit fittings (not supplied) or sealing glands (not supplied) to the conduit plate. The sealing cable nut should face into the
wall to allow clearance inside the mount arm cavity.
3. Prepare the conduit plate.
a. Thread the power and data cables through the holes of the conduit plate (supplied) and glands (not supplied) leaving approximately
12 inches of cable hanging from the wall.
b. Slide the conduit plate toward the mounting surface so that the mounting studs pass through the conduit plate to temporarily hold the
plate in place.
c. (Optional) If using sealing glands, be sure to tighten the glands.
4. Insert the PG9 gland.
a. Loosen the rounded nut on PG9 gland (supplied) so the wire can easily slide through the gland.
b. If installing duplex fiber cable, you must replace the rubber bushing of the PG9 gland with the two-hole bushing (supplied).
