For Port/Pin LEDs, see user's guide or IO-Link
Configuration document at www.balluff.com on
the product page.
Installation
You can find mounting accessories under
www.balluff.com on the product page.
► Fasten the module with 2 × M6 screws and a
tightening torque of 3 Nm using the mounting holes.
Requirements for complying with the protection
classes:
For IP68/IP69K, all plugs and caps must be properly
connected and the tightening torque of 0.6 Nm must be
observed (see data sheets of connectors and caps).

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 just 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 may be max. 20 meters
long, the connection cables between analog sensors,
digital sensors as well as actuators and hub max.
30 meters.

Electrical connection

Grounding
► 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.
To counteract EMC
interference, the functional
earth connection must be
used.
