2.4 Directions for installation
The terminals and KE have to be connected by a separate wire to the protective con-
ductor (PE). If the terminals L1, L2 of the device are connected to an IT system under
operation, the terminals
and KE must not be disconnected from the protective con-
ductor (PE).
In order to check the proper connection of the device, it is recommended to carry out a
functional test using a genuine insulation fault RF, e.g. via a suitable resistance, before
starting the ISOMETER.
The device variant -3.. is delivered with the following factory setting:
Please check if the basic setting of the ISOMETER® complies with the requirements of
the IT system to be monitored.
Response value

an
For correct setting of the response value in k Ω , it is useful to know the present value of
the insulation resistance of the photovoltaic system.
Subject to the IEC 62109-2 standard, a drop in insulation resistance at the input of the
photovoltaic inverter below a specified minimum value is not permitted. This resistance
is dependent on the performance range of the photovoltaic system.
Only one insulation monitoring device may be used in each
interconnected IT system.
When insulation or voltage tests are to be carried out, the device shall be
isolated from the system for the test period..
