Hardware Installation IP 240
Shielding of cable connections on the IP 240
Warning
To ensure noise immunity, shielded twisted-pair cables must be used for all IP 240
connections (inputs, outputs, 24 V power supply).
The following applies to shielding of the connecting cables:
• .The cable shields must be placed on a shield
bus near the cable entry in the cabinet.
• Braided shields must be secured over as large
an area as possible direct to the shield bus
(for instance with metal cable clamps which
span the shield).
• When using cables with foil shields, the
sheath wire incorporated in the shield must
be connected through as short a path as
possible (less than 3 cm) to the shield bus.
• The shielding must be extended from the
shield bus to the module.
• The shield bus must be conductively
connected to the supporting bar, the cabinet,
and the central grounding point in the
cabinet.
• The section entitled ”Installation Guidelines”
in the S5-115U Manual, Edition 2, provides
detailed information on grounding the cable
shields.
