InsulGard System Installation and Start Up Guideline5a b c dFigure 1-2. a, b – front and back view of Door mount InsulGard, c, d - front and back view of IG installed ona switchgear cabinet door.For a panel mount InsulGard, the Sensor Interface Board is installed on the panel under the Monitor. For sensorconnections, it is necessary to temporarily remove the Monitor from the panel. Put the unit aside until the sensorsare connected.2) AC power requirementsThe required AC voltage is specified on the InsulGard label. The InsulGard requires 1.0 Amp for power.For a 115VAC application please provide 10 Amps since there is a 115 volt outlet in the enclosure.3) Best location for InsulGard installationUsually the best location to minimize cables and conduits length is in the middle of installed sensor. The maximumdistance allowed between the PD sensors and the InsulGard (coaxial cables length) is ~150 feet.a) For a motor the best location of InsulGard enclosure installation is as close as possible to the motortermination box and its RTD termination box.b) For a switchgear line the best location of InsulGard (usually door mount) is in the middle of the line.4) InsulGard groundingInsulgard must be reliably grounded at place of its installation.a) For InsulGard in enclosure bring reliable ground to external grounding bolt on the enclosurebottom.b) Door mount InsulGard has a green wire connected to the back side of its case. This wire mustbe connected to ground (e.g. to grounded switchgear frame).5) InsulGard inputs for sensors connectiona) 15 channels (Ch1-Ch15) for PD sensors connectionb) 1 channel (Ch16) for noise cancellation (rarely used)c) Input for External Temperature sensor (for 100 Ohm Platinum RTD)d) Input for External Humidity sensorSensor InterfaceBoard
