ECS Device Installation Installing the ECS-INT50W
When mounting the ECS-INT50W in the ECS cabinet that contains an ECS-NVCM, it is necessary to mount the ECS-INT50W on the right
side of the control board. To do this, you will need the ECS-AMPMT mounting kit (ordered separately).
1. Mount the ECS-AMPMT plate into the cabinet using the six supplied screws. Orient with “Top” side up.
2. Secure the ECS-INT50W onto the six PEM studs on the mounting plate with six supplied screws. Ensure the side with only one
terminal block is at the top of the ECS-AMPMT. See the figure below.
