InsulGard System Installation and Start Up Guideline
7
A door mount InsulGard has the same wiring diagram as a panel mount, but without Din-Rail terminals. The power
supply voltage is connected straight to the power input of the unit. Door mount InsulGard installed on switchgear
compartment door usually has internal temperature and humidity sensors and doesn
’t need external sensors.
8) Panel mount InsulGard removing from its panel for sensor connection
For sensors connection to the Sensor Interface Board on a panel mount InsulGard, the unit must first be removed
from the panel.
To do this:
a) Gently disconnect the flat ribbon cable from the Sensor Interface Board on the left side of the monitor. Use
latching levers on both sides of the connector (see picture below) in small steps to lift the connector and
then pull the connector out of the socket (Figure 1-4).
Figure 1-4
b) Pull out wired green connectors from the right side of the monitor
c) Disconnect the monitor case grounding wire from ground terminal on Din-Rail
d) Unscrew 4 screws on front panel of the monitor and take it off
e) After sensor connection, install Insulgard back on the panel in reverse order
9) External auxiliary sensors (Temperature, Humidity and Load sensors) connection.
Sensors should be connected to the 12 contact terminal on the left side of the Sensor Interface Board as shown in
Figure 1-5 and table below.
