7.6 Signal cables
• Use screened cables with a cross-sectional area
of minimum 0.5 mm
2
and maximum 1.5 mm
2
for
external on/off switch, digital inputs, setpoint and
sensor signals.
• Connect the screens of the cables to frame at
both ends with good connection. The screens
must be as close as possible to the terminals.
See fig. 9.

connections
• Always tighten screws for frame connections
whether a cable is fitted or not.
• The wires in the motor terminal box must be as
short as possible.
