UMG 511
Current measurement
The UMG511 is designed for the connection of
current converters with secondary currents of
../1A and ../5A. Only AC currents, and no DC cur-
rents, can be measured.
Each current measurement input can be be loa-
ded with 120A for 1 second.
Fig. connection example, current measurement
using current converters.
Earthing current converters!
If a connection is foreseen for
earthing the secondary winding, this
must be connected to earth.
c
Caution!
The UMG511 is not suitable for
measuring DC voltages.
m
Caution!
Contact with the current measure-
ment inputs is dangerous!
