InsulGard System Installation and Start Up Guideline12b) The RTD-6 module goes in series with the existing motor RTD wiring. Verify that wires from the motor RTDsare connected to ”RTD In” side of the RTD-6 PD sensor. Verify that the coaxial cable central wire and shieldare connected to PD “+” and “-“ contacts accordingly. Verify that board is reliable grounded..c) If the existing RTD termination box is not large enough, an auxiliary box will need to be installed next to it tohouse the RTD Module and wired in appropriately.d) Up to six coax cables (12 if 2 modules are used) are required for connection to the Sensor Interface Board.After connecting RTD wires from stator to RTD PD module (to RTD In side), verify RTD connection andintegrity from RTD Out side of the module (right side). Write results down in the Table 5 in Appendix 2 -Link.e) After reconnecting RTD wires to temperature metering, verify proper reading on customer’s meteringsystem.2) Auxiliary sensorsa) TS – External Temperature sensor - 3-wire 100 Ohm platinum RTD in protecting shell. For rotating machinesusing spare 100 Ohm platinum RTD in stator winding is preferableb) HS – External Humidity sensorc) CT - Load (CT) sensor. 5 Amps primary current, ratio 1000:1. Mostly used for rotating machines. CT Sensorshould be installed over secondary wire of an existing metering current transformer.d) CTF - Split-core Primary Current Transformer (Flex Core) with CT sensor preinstalled on shortening jumperof Primary CT secondary winding. CTF is used if there is no metering CT in feeder termination compartmentand corresponding metering CT is too far from the InsulGard. Install CTF around a feeder cable of any phasein a motor feeder termination enclosure. It must be installed over the shielded part of the feeder cablewith cable shield grounding wire coming through the CT. In case of several feeders per phase, install itonly around one of the feeders.TS and HS sensors CT sensor CTF sensorFigure 1-11
