Directions for installation
The terminals
and KE shall be connected by a separate wire to the pro-
tective conductor (PE). If the terminals L1, L2 of the device are connected to a
system under operation, the terminals
and KE must not be disconnected
from the protective conductor (PE).
Risk of property damage due to unprofessional
installation!
If more than one insulation monitoring device is connected
to a conductively connected system, the system can be
damaged. If several devices are connected, the device does
not function and does not signal insulation faults. Make
sure that only one insulation monitoring device is
connected in each conductively connected system.
Ensure disconnection from the IT system!
When insulation or voltage tests are to be carried out, the
device shall be isolated from the system for the test period.
Otherwise the device may be damaged.
Check proper connection!
Prior to commissioning of the installation, check that the
device has been properly connected and check the device
functions. Perform a functional test using an earth fault via
a resistance that is suitable for the mains voltage.
