The WMK 100 has a 13" x 13" x 2.5" deep enclosure to mount the
PoleVault switcher and the power supply, with room for cable
management. It also has knockouts on all four sides which allow
external raceways to be used where necessary for cabling.

Installation

N

Before installation identify the type of wall (masonry or non-masonry) and the location where the WMK 100 will be
installed. This determines the installation approach and the type of fasteners needed to secure the plate to the wall.

1. Mount the base plate

Follow the steps within 1A or 1B below, as applicable.

N

1A. To mount the WMK 100 onto masonry walls:

N

Proceed to Step 2.

Refer to local building standards and codes to verify that the installation will meet the regulatory

requirements. Observe all local and national building and safety codes, UL requirements, and ADA
accessibility guidelines.

The base plate can be installed over an existing electrical

outlet. The opening fits standard sized 2.75" x 4.5" wall
plates. See figure 2 (inset).

i. Hold the base against the wall, level it, and mark the

positions of four slotted mounting holes (indicated by
+ marks in figure 2). Set the plate aside.

N

Use the top slot position at each mounting hole. Do not use

both top and left slots as this will make it difficult to slide the
plate down (see step iv).

ii. Using a masonry drill bit, drill 1.75" (4.4 cm) deep pilot holes

at the marked locations.

iii. Screw in masonry screws until a gap of 1/8" to 3/8"

(3 to 9 mm) remains between the wall and the screw heads.

iv. Align the base plate's slotted mounting holes over

the installed screws, then slide the plate down so
the screws fit into the slots.

v. At this time, lightly tighten all the screws to secure the plate

to the wall and verify level and position.

Do not over tighten, as the plate needs to be removed to attach the

switcher and power supply before cabling.

a. Grasp handle, collapse

b. Slide plastic washer

c. Cut off handle close to wall.

d. Hand screw in pan head
bolt until 1/8" gap remains.

1B. To mount the WMK 100 onto a non-masonry wall:

i. At the desired site locate the wall studs and mark their

locations.

N

For ideal installation secure the base plate to at least one

wall stud (see figure 3). Drywall Kap toggles can be used
for holes not aligned with studs.

The base plate can be installed over an existing electrical
outlet. The opening fits standard sized 2.75" x 4.5" wall
plates. See inset on figure 2.

ii. Hold and level the base plate against the wall and mark

the positions of the slotted mounting holes that are on
the stud lines (see figure 3, indicated by + marks). Where
applicable, mark the mounting holes on the wall for
drywall toggles. Set the plate aside.

iii. Drill 1.75" (4.4 cm) deep pilot holes at the marked

locations.

iv. Insert the self tapping screws into the pilot holes, until a

gap of 1/8" to 3/8" (3 to 9 mm) remains between the wall
and the screw heads.

N

If using toggle assemblies see figure 4 for installation

method.

v. Align the base plate's slotted mounting holes

over the installed screws, then slide the plate
down so the screws fit into the slots.

vi. At this time, lightly tighten all the screws to ensure plate

fits flush to the wall and verify level and position.

N

Do not over tighten, as the plate needs to be removed to

attach the switcher and power supply before cabling.

vii. If the cables are to be run behind the wall to the WMK

viii. Remove the base plate and cut out the marked area.

2. Mount the switcher and power supply

a. Remove the WMK 100 base plate from the wall, and with the

switcher's rear ports facing the cable access hole, align
the two corner holes in the base of the switcher with the two
outermost device mounting holes in the WMK 100 base plate.
Secure with the supplied 440 x ¼" screws.

b. Attach the power supply above the electrical outlet cutout,

with the supplied hook-and-loop straps. Attach it so the cables
are easily and safely routed to the electrical outlet and switcher
alike.

c. Re-attach the plate to the wall and secure firmly.
