1.8 Safety
If the device is used outside the Federal Republic of Germany, the applicable local standards and
regulations must be complied with. In Europe, the European standard EN 50110 applies.
I
Danger! Risk of fatal injury due to electric shock! Touching live parts of the system car-
ries the risk of:
- a fatal eleCtriC shoCk
- Damage to the eleCtriCal installation
- DestruCtion of the DeviCe
Before installing anD ConneCting the DeviCe, make sure that the installation has Been
De-energiseD. the rules for Working on eleCtriCal systems must Be oBserveD.
1.9 Intended use
The ISOMETER® is an insulation monitoring device according to IEC 61557-8 for IT systems. It mon-
itors the insulation resistance of unearthed 3(N)AC, AC and DC main and control circuits (IT sys-
tems). The range of application and the maximum permissible system leakage capacitance of the
different models are specified in the chapter "Technical data".
The DC components existing in AC/DC systems can have an influence on the response behaviour
if an insulation fault occurs downstream of rectifiers with an electrolytic capacitor.
The separate supply voltage of the iso415R-24 also makes it possible to monitor a de-energised
system.
Intended use implies:
• Observance of all information in this operating manual
• Compliance with test intervals
In order to meet the requirements of applicable standards, customised parameter settings must
be made on the equipment in order to adapt it to local equipment and operating conditions.
Please heed the limits of the area of application indicated in the technical data.
Any other use than that described in this manual is regarded as improper.
