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

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
.

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

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).

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

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.

N

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

switcher and power supply before cabling.

Proceed to Step 2.

The plate can be aligned over an existing electrical outlet.
