side shielding signals: in these cases, considering the above,
the shield must also be connected.
In all cases the connection of the Terminal side shield (pin 1)
must never be carried out.
Earth potentials obtained from DIN guides,
machine framework, doors of the electric control
boards etc. are not allowed and it is a good ides to
avoid equipotential earth bars where earths converge
coming from inverter, drive, step-by-step motor type
loads and all those loads that generally can be a source
of great interference..
The failure to comply with these indications can jeop-
ardise the compatibility of the YT-PLC system with EMC
regulations in force.
