Mounting
Mount the EVO/ECM-Modbus RTU inside a metal control cabinet or enclosure. Make sure the
enclosure is earthed. When mounting the low voltage power transformer in the same enclosure,
be sure to separate the high and low voltage sections of the enclosure, as required by good safety
practice, and building codes.
To reduce EMI (electro-magnetic interference), tightly fasten the control mounting posts to an
earthed metal surface of the enclosure. Ensure good electrical contact between the mounting
posts and electrical ground.
Low voltage communications and motor control wiring can be routed into the low voltage section
of the metal enclosure or be plugged into opening in the side of the enclosure. All external
connections are made to one side of the board. Make a rectangular cutout in the side of the
enclosure when the application requires external plug in of motor and communication cables.
