UMG 96RM-P/-CBM
Current transformer input I4
The 4th current transformer input is intended for
the connection of current transformers with secondary
currents of ../1A and ../5A. The factory default for
the current transformer ratio is 5/5A and must be adapted
to the current transformer employed if necessary.
Direct measurement without a current transformer is not
possible with the UMG 96RM-P/-CBM.
Only AC currents can be measured - DC currents cannot.
In doing so, with a voltage only an apparent current
measurement is possible due to the multiplier being
missing. Power measurements with the help of this
input are thus not possible.
c
Important!
The current measurement inputs are
dangerous to touch.
m
Important!
The UMG 96RM is not suitable for
measuring DC voltages.
c
Earthing of current transformers!
If a connection is provided for the earthing
of secondary windings then this must be
connected to the earth.

It is not necessary to configure a connec-
tion schematic for the I4 measurement
input.
