The front panel of the communications module must be connected to the
front panel of the CS7 using the cables provided with the CS7.
The screen of the data transfer cable (bus cable) must be grounded to a
grounding rail through the largest possible surface area where the cable
enters the equipment.
In addition, the screen in the connector housing must be connected to the
housing. The connector must be tightly screwed to the communications
module.
Further information on EMC and ambient conditions, refer to Section
„General technical data"
Each receptacle of the CS7 support module has 2 LEDs, which allow
