1.1.4 Grounding
To counteract EMC interference, the functional earth
connection must be used.
►
Connect the earth terminal to the functional earth (FE)
of the machine.
The FE connection between the housing and
the machine must have a low impedance and
be as short as possible.
►
Use the grounding strap included in the
scope of delivery.

5.3 Shielding and cable routing
Shielding
The connection to the higher-level IO-Link master and the
connection to the extension device is made with a
standard sensor cable.
Since the housings are made of non-conductive
material, interfering signals cannot flow through
the shielding to the FE. The shielding of the cable
should be connected to the FE (functional earth)
either on the sensor or module side. If connection
is not possible on the sensor side, the adapter
cable available from Balluff as an optional
accessory can be used. The adapter cable routes
the shielding of the cable to Pin 5 of the port and
thus to FE.
Digital sensors and actuators are connected to the
described hubs using standardized, unshielded sensor
cables.
Cable length
The IO-Link connection cable and the cable for connection
to the extension device may be max. 20 meters. The
connection cables between digital sensors and actuators
and hub may be max. 30 meters.
