Installation

Mount the Enclosure to the Wall

Step 1: Remove the front cover of the enclosure

to reveal the four mounting keyholes.

Step 2: Align the enclosure to the wall and mark

the mounting keyholes. Alternatively,
use the measured keyhole dimensions
located in the graphic (right) to mark the
hole locations for the mounting
hardware.

Step 3: Drill the holes and install the mounting

hardware.

• Mounting hardware is not
supplied.

• Expose at least 1” (25mm) of
threads for mounting.

Step 4: Attach the enclosure to the mounting

hardware, where the back side is flush
to the wall, then tighten the mounting
hardware.

Step 5: Insert a screw into the provided wall anchor point, located between the left side mounting

keyholes of the enclosure. Populating this hole with a screw provides additional security that
the enclosure will not fall from the wall during a seismic condition.

Note:

If you are using Cat5 (or Cat5e) wiring, an
external Echo Cat5 Termination Box (is required.
Contact ETC for ordering details. Control wiring
instructions between the termination box and
this Wall Mount Station Power Supply with
Auxiliary Power are provided with the Cat5
termination box installation instructions.
