Current measurement via I1 to I4
The UMG 96RM-P/-CBM is designed to have cur-
rent transformers with secondary currents from ../1A
and ../5A attached cia terminals I1-I4. The factory de-
fault for the current transformer ratio is 5/5A and must
be adapted to the current transformer employed if ne-
cessary.
Direct measurement without a current transformer is not
possible using the UMG 96RM-P/-CBM.
Only AC currents can be measured - DC currents can-
not.
Via the current measurement input I4 only an apparent
current measurement is carried out thanks to the lack
of a multiplier. Power measurements are therefore not
possible using the I4 input.
c
Caution!
The current measurement inputs are dan-
gerous to touch.
