Earthing auxiliary circuits
“Earth vaults in control current circuits must not lead to
unintentionable start-up or dangerous movements of a machine,
or prevent shut-down of a machine. In order to fulfil this
requirement, one side of the control current circuits should be
connected to the protective conductor system and the coils and
switch elements should be correspondingly arranged.
For a control current circuit which is not connected to the
protective conductor system and supplied by a transformer, an
insulation monitoring unit must be included that reports an earth
fault and automatically switches of the circuit following an earth
fault.”
(VDE 01136.2.2)
Our earth test/disconnect terminals were specially designed for
use in control current circuits. They are designed so that reliable
and rapid disconnection from earth connection and an exact
display of the operating statuses are guaranteed. The mode of
operation makes a distinction between three different
conditions:
1. Operating mode
In operating mode, the control current circuit is solidly
connected to the earth connection via the closed side link. In
this way, a possible earth fault can be detected with the help of
a fuse and/or an r.c.c.b. because the leakage current can be
discharged to earth in the event of a fault.
2. Test mode
The test mode makes it possible to check the insulation
condition of the installation. The earth connection must be
disconnected for insulation measurements with voltages greater
than the rated voltage of the earth test/disconnect terminal.
3. Fault mode
If an earth fault occurs during operation in an earthed control
circuit , our earth test/disconnect terminals make it possible to
switch to a non-earthed control-circuit. This bridges the time
required to correct the fault, i.e. the machine can continue to
operate.

SAKT E SAKA 10
– Side link closed
– Auxiliary current circuit earthed
– “Green” indicator illuminated
Test mode
For insulation measurements with voltages >U
rated,
the earth
connection must be disconnected.
SAKT E SAKA 10
– Side link open
– Auxiliary current circuit not earthed
– No earth fault
– “Green” and “red” indicators no indication
light up with reduced
intensity
– Earth connection disconnect
For insulation measurements with voltages >U
rated,
the earth
connection must be disconnect.
