TN and TT systems
Measurement is designed for 3-phase sys-
tems with neutral conductors (TN and TT
systems).

IT systems
The UMG507 is only conditionally suitable for
use in IT systems, as the measurement volt-
age is measured at the housing potential and
the input impedence of the device causes a
leakage current to the earthing. The leakage
current can cause the insulation monitoring
in IT systems to respond. It must also be en-
sured that the maximum permissible voltage
at the inputs of the UMG507 are not exceeded
to earth (e.g. in case of a phase-to-earth fault).
The connection options shown in Fig. 4.1b
(with PEN conductor) or Fig. 4.6a (without a
PEN conductor) are suitable for IT systems
without restriction. Here the IT system is insu-
lated through the use of voltage transformers.
It is absolutely necessary to connect
the
PEN conductor N.
