UMG 96RM-EL
Current measurement
The UMG 96RM-EL is designed for connecting cur-
rent transformers with secondary currents of ../1A and
../5A. The factory set current transformer ratio is 5/5 A
and may need to be adapted to the current transform-
ers.
It is not possible to perform a direct measurement with-
out a current transformer with the UMG 96RM-EL.
Only AC currents (and not DC currents) can be meas-
ured.
c
Attention!
The current measurement inputs are
dangerous to touch.
m
Attention!
The UMG 96RM-EL is not suitable for the
measurement of 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.
