5.3.2 Motor wiring
The power wiring must be made by means of a 6-pole terminal board; the following picture shows the pin con-
figuration.
Here are the specifications of the cables to be used for wiring:
The terminal board contacts must be tightened by means of a flat-blade screwdriver (blade width: 3.5 mm) or
by means of a cross-head screw-driver (PH 0); the recommended tightening torque is 0.55 Nm ±10%.
The conductor section size depends on the maximum current; in case of installation in the electrical panel of
a machine, please consider that the EN 60204-1 Standard does not allow the use of cables with a cross-section
smaller than 0.75 mm2 inside the housings and 1.0 mm2 outside (0.75 mm2 for multicore cables). To connect
the motor, a shielded multicore cable with a cross-section of 0.75 mm2 may be an excellent choice in most
applications.
The motor must be connected as shown in the following picture:
