1. How to use this documentation effectively
This operating manual is intended to address qualified experts in electrical en-
gineering!
Note:
This manual describes an ISOM with software version 1.5
1.1 Use for the intended purpose
The ISOM is exclusively intended for:
 monitoring the insulation resistance of IT systems and
 localization of insulation faults in combination with insulation fault evalua-
tors DLD4....
Any other use, or any use which goes beyond the foregoing, is deemed to
be use other than for the intended purpose.
1.2 Safety information
General safety information
In addition to this operating manual, the documentation includes the supple-
mentary sheet „Important safety instructions for SOCOMEC Products“.
Device-specific safety information
Only one insulation monitoring device may be used in each intercon-
nectedITsystem.
