This section provides step-by-step instructions for installing the ESA Monitoring System enclosure.
-
Mount the ESA System enclosure at the planned location.
-
Install the conduit between the ESA Monitoring System and each voltage bus pickup point.
-
Install the conduit between the ESA Monitoring System and each current sensor pickup point. Current sensor cables may be combined in conduit as long as it is appropriately sized. Current sensor cables should not be combined with PT cables.
-
Install the conduit for 120VAC power. Minimum circuit size: 20A 120VAC power supply free of non-linear loads. Consider a circuit with isolated ground.
-
Install the conduit and wire for data connection. Cutsforth recommends Cat6a or fiber connection (media converter required).
-
Connect protective earth conductor per local electrical codes.
-
Install wire for 120–240VAC supply per local electrical codes.
-
If required by local electrical codes, install an external switch or circuit breaker near the equipment. Ensure equipment is positioned so that it will not be difficult to operate the external disconnecting device.

The ESA system potential (voltage) measurements can be made by paralleling to an existing bus PT (typical in medium voltage systems) or paralleling directly from the bus (low voltage system).
Medium voltage connection points may be made from the load side of the existing PT fuses, existing relay test switches, or relay voltage inputs.
Low voltage connection points may be directly connected to the bus, auxiliary connection points on an MCC breaker, or existing motor test points.
It is important to specify the line-to-line voltage magnitude and configuration (delta/wye) when ordering your ESA monitoring equipment so the appropriate input module can be included in your build.
The Cutsforth Monitoring System is designed to be integrated into InsightCMTM software. For more information on InsightCMTM, including specific server requirements, visit the InsightCMTM README on the Cutsforth Support webpage at https://support.cutsforth.com.
The plant must provide a PC or Server for InsightCMTM meeting the requirements listed at the above link. Cutsforth is not responsible for the configuration of server-side deployment. Ensure the plant's InsightCMTM server is set up and ready for communication to field equipment in advance of system commissioning by Cutsforth.
