Instructions and information for installing the EMI Monitoring System enclosure |
This section provides step-by-step instructions for installing the EMI Monitoring System enclosure.
Mount the EMI Monitoring System and Power Supply enclosures at the planned location.
Install the conduit between the EMI Monitoring System enclosure and the Power Supply enclosure.
Install the conduit between the EMI Monitoring System and each HFCT using separate conduit for each HFCT run.
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.

*Enclosures do not come with conduit holes pre-drilled. Conduit sizing and hole placement is customizable.
**Install each HFCT run in individual conduit runs and do not share conduits so as to avoid any cross talk between CT circuits.
