1.2 Installation of the InsulGard Sensors
Monitored object and InsulGard must be de-energized.
The best way to de-energize InsulGard is to de-energize
the incoming power supply line. On a panel mount InsulGard open the fuse located on the DIN-Rail.
All sensors have default cable length of 65’ (20m). Custom lengths may be specified at the time of order entry.
Install all sensors in accordance with their manuals
in “InsulGard Sensors Manual”.
