Current measurement
The UMG605US is designed for the
connection of current transformers with
secondary currents of ../1A and ../5A. Only
alternating currents, not direct currents, can
be measured.
Each current measurement input can be
permanently loaded with 6A or for 1 second
with 100 A.
Earthing current transformers
If a connection is provided for earthing
the secondary winding, this must be
connected with earth.
Fig. 24.1 Connection example, current
measurement via current transformers.
Important!
The UMG605US is not suitable for
the measurement of direct voltages.
Attention!
The current inputs are live.
