Screening
Twisted screened cable should be used for connections
via the RS485 interface.
• Earth the screens of all cables that lead to the cabinet
and at the cabinet entry.
• Connect the screens over a generous area and in a
manner that will conduct well, to a low-noise earth.
• Gather the cables mechanically above the earthing
clamp in order to avoid damage due to cable
movements.
• Use suitable cable glands to feed the cables into
the cabinet, for example, armoured conduit couplings.
