(1.4) Coupling monitoring (not for isoHR1685D-925)

The ISOMETER® continuously monitors the coupling of energised systems. The coupling of de-
energised systems is monitored at 24-hour intervals. This monitoring function can be activa-
ted or deactivated.

The device is active.
The device DOES NOT measure the insulation resistance and is discon-
nected from the system to be monitored (system disconnection, not
for isoHR1685D-925). The IT system is NOT being monitored!
