Terminal block X3 Voltage measurement
(M102 only)
M102 provide three voltage inputs sup-
porting up to 690V ac direct connection. It
can be used for three phases and single
phase application.
Voltage phase connection shall follow the
terminal definition listed in table 8 to en-
sure correct power factor and phase se-
quence reading.
In case of single phase, the voltage con-
nections are X3:9 & 13 as listed in table 9.
Voltage measurement circuit is included in
typical wiring diagram Fig 13.

Wiring Tip:
In case external voltage transformer (VT) is
used,take care of the connections from VT
secondary which should be wired according to
table 8. (Fig 11)
VT type may be a single-phase type or a
three-phase transformer with Yy0 connection.
