3.2 Surface-Mounting the Optional Expansion Board
After determining where to place the optional Expansion Board, check to ensure that you have all the
hardware required to install the panel on the surface of a wall. Obtain the needed tools and material.
Required tools
• Electric drill (if surface is too hard to drive screws without pilot holes)
• Screwdriver
• Marker to denote layout of holes
• Four screws, each #10
3.2.1 Mounting the Panel
1. Mark the wall for mounting holes, using the back of the unit as a template (see Figure 5).
2. Drill holes, if required, to install the four #10 screws that will secure the optional Expansion
Board to the wall. Clean up the debris.
3. If the wall material is not strong enough to hold the screws securely, use wall anchors.
4. Install the top two screws—the screw heads must be small enough to slip through the larger,
bottom portion of the pear-shaped mounting slot in the Expansion Board (see inset in Figure 5).
The screws must also be large enough to extend over the edges of the top of the mounting slot.
5. Hang the Expansion Board on the screws, letting the panel slip down until the screws are in the
smaller, upper portion of the slot.
6. Tighten the screws until they are snug.
7. Insert the remaining two screws in the bottom holes on the back of the panel and tighten.

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.
!
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.
