Do not connect the neutral conductors of the single-phase networks to
each other on the primary side of the voltage transformers
The neutral conductors of the different single-phase networks must not be
connected to each other on the primary side of the voltage transformers.
If they are, unwanted currents can flow between the different networks.
The nominal input voltage is:
- u
LN
= 200 V
RMS
if a voltage ≤
120 V
RMS
is parameterized for the “Secondary
Voltage” setting
- u
LN
= 400 V
RMS
if a voltage > 120 V
RMS
is parameterized for the “Secondary
Voltage” setting
Parameter 47 is used for the setting.
Since there is no common neutral conductor, the optional connection of IN+ and
IN− is omitted.
