UMG 511
Current direction
The current direction can be individually corrected
on the device using the available serial interfaces
for each phase.
If connected incorrectly, subsequent reconnection
of the current converters is not necessary.
Current converter connections!
The secondary connections of the
current converter must be short-
circuited to these before the electri-
city cables are disconnected from
the UMG511!
If a test switch is available which
automatically short-circuits the cur-
rent converter secondary cables, it
is sufficient to put these in the „test“
position, if the short-circuiters have
been tested beforehand.
c
Open current converters!
Voltage peaks that are dangerous
to touch can occur to current con-
verters that are operated with the
secondary side open!
With „open-protected“ current
converters, the winding insulation
is measured so that the current
converters can be operated open.
However, these current converters
are also dangerous to touch when
operated open.
