InsulGard System Installation and Start Up Guideline141.4. InsulGard system installation for a motor1) Typical Insulgard system for a motorA typical InsulGard for a motor is usually installed on a panel and in a Nema-4X enclosure. Examples of installationshown below:a bNote: If a conduit is installed on top of the enclosure (b), be sure to use appropriate seals to prevent water fromentering.For InsulGard installation and sensor connection refer to section 1.1 above - Link. For sensor connection, you musttemporarily remove the InsulGard monitor from the panel and put aside until the sensors are connected.Typical sensor installation and to InsulGard connection for a motor is shown in Figure 1-12. The sensors are:a) Three IPDS sensor installed in the motor terminal boxb) One RTD-6 PD Sensor Board installed in motor RTD terminal box. For large motors and generators withmany RTDs, a second board is needed for better monitor stator winding conditionc) External Temperature and Humidity sensors installed in the Motor terminal boxd) Load sensor installed on the wire of secondary winding of motor metering CT. If there is no close motormetering CT, the CTF sensor can be installed on phase A motor feeder. (If feeder has few cables, installCTF only on one of them.)e) Sometimes RFCT sensors can be additionally installed on wires that provide grounding of cable shields forall three phases cablesFor sensor installation refer to section 1.2 and 1.3 above ( Link ) and some additional specifics describedbelow.
