InsulGard System Installation and Start Up Guideline17c) IPDS installed on phase A should be connected to channel 1 (Ch. 1).d) If RFCT sensors are used instead of IPDS sensors, look for the corresponding manuals.4) RTD-6 PD sensor installation in a motor RTDs boxa) Verify that the existing winding RTD termination box at the Motor frame is large enough to install the RTDmodule. Most RTD termination boxes are large enough to accommodate the RTD-6 Module.b) The RTD-6 module goes in series with the existing RTD wiring.c) Many times the existing RTD terminal board can be removed and the RTD-6 module inserted in its place.d) 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.e) Run six coax cables to the InsulGard (12 if 2 modules are supplied for 12 RTDs) and connect to the SensorInterface board.f) Run one 3 conductor 22 AWG shielded cable from a spare or provided winding RTD for temperaturemeasurement instead of a temperature sensor.5) Auxiliary sensors installation in the motor termination boxa) Install external Humidity sensorsb) Install external air Temperature sensor if supplied and no winding temperature RTD (platinum 100 Ohm) isavailable. Generally, temperature metering should represent winding temperature as close as possible.Using one of the winding RTDs is preferable. Other options are RTD in hot air, then external Temperaturesensor somewhere inside motor volume and feeder termination box next to the Humidity sensor.c) The Load Current sensor goes around the secondary connection of the motor primary current transformer.This option is possible only when the metering CTs are installed over the motor leads in the feederconnection box. Differential CTs are not applicable for the load current monitoring.d) If there are no metering CTs, use auxiliary FlexCore CT installed over the shielded part of the incomingfeeder.NOTE: Make sure wires are not near any high voltage source. Do not use "sticky pad" type of tiedowns!!Check all sensor connections (refer to section 1.3 - Link )After all sensors are connected, install IG back on its panel (refer section 1.1 - Link), connect power and make allother required connection to IG outputs (to relays and interfaces)
