Installation and connection

connection must be as shown in the diagram.
The measuring procedure then is similar to
that for the extended connection (see section
2.8).
If the control transformer taps the voltage
signal between a phase conductor and
neutral, the terminal ”Meas” must remain
unused.
Figure 6 Connection in special cases
2.10 Connection in special cases
The type of connection shown above should
be used if the voltage between the phase
conductors does not exceed 240 V AC.
The following general principles apply:
If the terminal ”Meas” remains unused, the
voltage for terminals ”L” and ”N” must be
connected to a phase conductor and to the
neutral conductor.
