NOTE
The illustration of the consistent ground connection of
the instrument transformers is simplified in the following
connection examples. The secondary windings of the
current transformers installed in a high-voltage power
system must be grounded on one side.
DANGER
Hazard due to high voltages in the event of a break-
down of the winding insulation
Non-observance will lead to death or serious injury.
Ground the secondary windings of the current trans-
formers on one side. They are installed in a high-volt-
age power system.
Important notes for the following circuits:
NOTICE
Take into account the operating conditions at the cir-
cuits 9.1, 9.4 and 9.5 in accordance with chapter 6 in
the device manual.
NOTE
For SICAM MMU devices with galvanic isolated voltage
measuring inputs, the electrical connection PE-N is not
mandatory for the circuit 9.2.
