means a primary voltage of 10,000 V and a secondary voltage of 100 V. The input field
ranges from 1V to 9,999kV for the primary voltage and 100V or 500V for the secondary
voltage.
For the item
Phase allocation of measuring voltage
, the phase that is taken from the
measuring voltage must be given, e.g. phase U = L1N.
For a phase/phase measurement the entry would be L23, for instance.
Using the item
Zero-point creator
, the controller can be activated via a zero-point cre-
ator.
For energy supply networks with outer conductor connected to the earth potential,
suitable control gear with
electrical isolation (e.g. voltage transformer) must be used.
These transducer adaptors (zero-point creator) are suitable for creating a virtual low-im-
pedance neutral point for the device in a three-phase network without neutral conductor.
In the 700 V variant, this also serves to adapt the measuring voltage to the device.
Make sure that the device is configured for the operation with a zero-point creator.
Transformers are available in the following variants:
Type 400/100:
Primary:
400 V phase-phase voltage
Secondary:
100 V phase-phase voltage
Type 700/100
Primary:
700 V phase-phase voltage
Secondary:
100 V phase-phase voltage

Target cosine and freeze mode submenu
The target cosine submenu contains the following items:
1. Target cosφ for power consumption
2. Target cosφ for power recovery
3. Alarm cosφ (message when alarm cosφ is not reached after set
alarm delay time has elapsed)
For the items Target cosφ for power consumption and Target cosφ
for power output, a value from inductive 0.80 to capacitive 0.80 can be entered.
If active power recovery is detected, this is signaled by the symbol
in the display.
Under the item Alarm cosφ a value of inductive 0.50 to capacitive 0.50 can be entered.
