3.3 Flush-Mounting the Optional Expansion Board
The optional Expansion Board may be flush-mounted according to company practices—either with
screws through the sides of the panel into wall supports or with hanging hardware that attaches to
the back of the panel. After determining how and where to place the unit, check to ensure that you
have all the hardware required to install the panel in the wall. Obtain the needed tools.
Required tools
• Saw
• Electric drill
• Screwdriver
• Marker to denote layout of the hole to accommodate the optional Expansion Board
• Trim ring and associated hardware
• Mounting hardware
3.3.1 Mounting the Panel
1. Mark the wall for the cutout to accommodate the panel, using the back of the unit as a template.
2. Drill a pilot hole for the saw blade, if required.
3. Use the saw to cut out the marked section of the wall (if not new construction).
4. Rest the optional Expansion Board in the wall and mark where mounting screws will be inserted
into the wall studs or other support member.
5. Remove the panel and drill the holes for the mounting screws or wall anchors. Clean up the
debris.
6. Reverse the slide direction of the rectangular access doors on the top and bottom of the Expansion
Board. Leaving the doors as shipped from the factory prevents them from being opened when the
panel is flush mounted in a wall.
7. Attach any field-supplied mounting hardware.
8. Reinsert the assembly into the wall.
9. Insert and tighten the screws or wall anchors.
NOTE
Removing the conduit knockouts before mounting the optional Expansion Board on the wall
will ease installation and prevent strain on the mounting hardware and wall. It is imperative
to remove the knockouts if the unit is to be flush-mounted.
The rectangular access doors on the top and bottom of the Expansion Board must be reversed
so they slide the opposite direction. Leaving the doors as shipped from the factory prevents
them from being opened when the panel is flush mounted in a wall.
!
CAUTION
Check building plans and other relevant documents to determine whether mounting the
optional Expansion Board at the selected location might cause cutting or otherwise damaging
electrical or communication wiring or pipes.
