8.1 Wiring examples
The application examples shown are suggestions. They however do not
release the user from carefully checking whether the switchgear and its
set-up are suitable for the individual application.
The wiring diagram is shown with guard doors closed and in a de-
energised condition. Inductive loads (e.g. contactors, relays, etc.) are to
be provided with suitable interference suppression circuitry.
Avoid laying proximity switch connection cables in areas where strong
interference signals are present (e.g. frequency converters or cable
leads from powerful electric motors); the utilisation of shielded cables
may be necessary.
