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
240VAC.
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.
If the terminal ”Meas” is used, the voltage
for terminals ”Meas” and ”L” must be
connected each to a phase conductor.
For all types of connections (figure 3 to 6)
it is also possible to connect the current
transformer in phase conductors L2 or
L3. In this case, the voltage connections
to the phase conductors should be ex-
changed accordingly.
If the control relay operates with auto-
matic response current recognition, con-
nection errors would be reported.
If response current recognition is deacti-
vated, then an error in the connection will
lead to functional errors during subse-
quent operation.
