UMG 96RM-E
Analog inputs
The UMG 96RM-E has 2 analog inputs which can
be used for one residual current measurement or one
temperature measurement. The measurement is done
using terminals 32-34 (input 1) or 35-37 (input 2).
The analog inputs can be used for residual current
or temperature measurement in accordance with
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 exhibit reinforced
or double insulation from 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.
