UMG 96RM-PN
Analogue inputs
The UMG 96RM-PN has two analogue inputs, each of
which can be used for a residual current measurement
or a temperature measurement. A measurement is
performed here via terminals 32-34 (Input 1) and 35-37
(Input 2).
The analogue inputs can be used either for residual
current measuring or temperature measuring, per
the following table:
Measurement
Terminal
Temperature
32/34 (Input 1) and
35/37 (Input 2)
Residual current
32/33/34 (Input 1) and
35/36/37 (Input 2)

Attention!
Operating equipment connected to
the analogue inputs must feature
reinforced or double insulation to the
mains supply circuits!
Example - temperature sensor:
A temperature sensor in close proximity to
non-isolated
mains cables should measure within a 300V CAT III
network.
Remedy:
The temperature sensor must be equipped with
reinforced or double insulation for 300V CAT III. This
equates to a test voltage for the temperature sensor of
3000V AC (duration 1 min.).
Example - residual current transformer:
A residual current transformer should measure on
isolated mains cables within a 300V CAT III network.
Remedy:
The insulation of the mains cables and the insulation
of the residual current transformer must fulfil the basic
insulation requirements for 300V CAT III. This equates
to a test voltage of 1500V AC (duration 1 min.) for
the insulated mains cables and a test voltage of 1500 V
AC (duration 1 min.) for the residual current transformer.
