8.1 APPENDIX A1 - INPUT-OUTPUT SCHEME
8 APPENDIX
INPUT
For all connections longer than 5m or in environments particularly subject to disturbances due to
power transmission, the use of shielded cables is strictly recommended, with the shield connected
to earth on only one end.
OUTPUT
In case of connections to power relays coils or contactors, it is strictly recommended install protec-
tion devices - like varistors, trapping diodes, etc. - directly on the coils in order to avoid overvoltage
phenomena which can produce disturbances along the cables and/or damage the coils and/or control
relays contacts.
