1. Intended use

The ISOMETER® isoES425 monitors the insulation resistance R
AC, AC/DC and DC power supplies (IT systems) for energry storage up to
mains voltages of AC/DC 400 V. In order to meet the requirements of appli-
cable standards, customised parameter settings must be made on the equip-
ment in order to adapt it to local equipment and operating conditions. Please
heed the limits of the area of application indicated in the technical specifica-
tions.
Any use other than that described in this quickstart is regarded as improper.
20
To ensure that the ISOMETER® functions correctly, an internal
resistance of 1 kΩ must exist between L1/+ and L2/- via the
the source (e.g. the transformer) or the load.
In the event of an alarm message, the insulation fault should
be eliminated as quickly as possible.
