Appendix 2. Installation / Commissioning Report
(To fill out below tables you can copy this appendix to word file.)
Write down name of the object and InsulGard s/n.
Table 1
Check power voltage for the monitor.
For panel mount IG switch the breaker on (fuse out).
Check power connections on DIN Rail terminal strip for enclosure and panel mount monitors. For door mount
monitors check power on corresponding fuse block.
Contacts are different for InsulGards of different versions
– consult the appropriate winding diagram as needed.

Table 3 (For Rotating Machine applications only)
Integrity of RTD temperature metering circuits could be verified on contacts on right side of an RTD-6 board before
the wires from temperature measuring device will be reconnected to the board:
a. resistance between contacts 2 and 3 for each RTD should be less than 2 Ohm;
b. resistance between contacts 1 and 2 or 3 should be ~100-130 Ohm for platinum RTDs and ~10-15 Ohm for
copper RTDs;
c. resistance between RTD shield contact 4 and any of the contacts 1 , 2, 3 should be >150kOhm.
Write results down in the table below.
