4.7.2 Mounting the ECS-125W
The ECS-125W is equipped with a separate enclosure. Refer to Section 3.1 when selecting a
mounting location for the ECS-125W.
The panel should be accessible to main drop wiring runs. It should be mounted as close to the center
of the building as possible and located within a secured area, but should be accessible for testing and
service.
Mount the control panel cabinet so it is firmly secured to the wall surface. When mounting on concrete,
especially when moisture is expected, attach a piece of 3/4-inch plywood to the concrete surface and
then attach the cabinet to the plywood. Also mount any other modules to the plywood.
The cabinet can be surface or flush-mounted. If you will be flush-mounting the cabinet, the hole for the
enclosure should be 14.5" W x 24.75" H x 3-7/16” D (36.8cm W x 62.9cm H x 8.73cm D). Do not flush-
mount in a wall designated as a fire break. The Outside dimensions of the cabinet are 16" W x 26-1/4”
H x 4-1/8” D (40.64cm W x 66.68cm H x 10.48cm D).
Follow these steps to properly mount the cabinet.
1. On the mounting surface install two screws level with each other 11" apart.
