vii. Align the slotted mounting holes in the base plate
over the installed screws, then slide the plate down so
the screw fit into the slots.
viii. Verify level and position, and tighten down all the
screws to secure the plate flush to the wall.
Step 2. — Mount the Switcher, Power Supply, and Accessory Device
NOTE: Always use a power supply supplied or specified by Extron. Use of an unauthorized power supply voids all
regulatory compliance certification and may cause damage to the supply and the end product. Unless otherwise stated,
the AC/DC adapters are not suitable for use in air handling spaces or in wall cavities. The installation must always be
in accordance with the applicable provisions of National Electrical Code ANSI/NFPA 70, article 75 and the Canadian
Electrical Code part 1, section 16. The power supply shall not be permanently fixed to a building structure or similar
structure.
a. Invert the switcher and place it (base up) on a flat surface.
Place the mounting plate flat on the switcher base with the plate
tabs (raised section up) over the edge of the front panel. Align the
two mounting holes in the switcher base with the corresponding
holes on the mounting plate. Secure the plate to the switcher with
the supplied 4-40 x ¼ inch screws.
b. Secure the switcher mounting plate (with switcher
attached) to the base plate by sliding the two tabs into
the slots at the bottom edge of the base plate. Secure to
the standoffs with 4-40 x 3/16 inch screws (see figure 5).
c. Secure the power supply to the right of the electrical outlet cutout
by threading the supplied tie wraps through the loops on the
base plate. Attach it so the cables are easily and safely routed
to the electrical outlet and switcher alike.
d. An optional ¼ rack, 3 inch deep accessory device, such as the
Extron IPL TS2, can be installed on the WMK 160 base plate.
To do so, place the device towards the top of the base plate,
align the holes on the base plate and the device, and secure with
the supplied 4-40 x 3/16 inch screws.
Step 3. — Run Cables
Run signal cables from the proposed PVT input wallplates, control
device location, and the speakers to the WMK 160 location. Cables can
be routed behind the walls, or through a surface raceway (for example,
Wiremold
® V700 or 2400 series) directly to the WMK 160.
3A. If running cable behind the walls:
i. Run all the cables from the various locations to the WMK and through
the access cutout.
3B. If using a surface raceway:
i. Slide the WMK cover over the base plate, then identify and
mark the most suitable raceway entrance to the WMK 160.
ii. Run the raceway from the signal source, speaker, and display
locations to the marked raceway entrance at the WMK.
iii. Remove the WMK cover, and remove the desired knockout.
iv. Attach the raceway to the wall. Run cables from the sources
and outputs through the raceway to the WMK.
