Functional earth
NOTICE
Always connect the housing of the safety sensor to functional earth or ground!
Ä The housing of the safety sensor must always be connected to earth (functional earth) or
machine/vehicle ground.
Ä If the safety sensor is attached to a non-conductive material (e.g. a concrete wall), the hous-
ing of the safety sensor must be earthed.
• Factory recommendation: Functional earth via a ground strap/braid (low impedance for RF).
Connection points for self-tapping screws used for the ground connection are provided and labeled on
the bottom of the connection unit (see chapter 8.3 "Connection unit CU429").
• Functional grounding via the shield of the connection cable.
For grounding, the shield of the connection cable in the switch cabinet must be connected to earth or
machine/vehicle ground.
NOTICE
Make sure that potential equalization is provided!
Ä If the housing of the safety sensor or the mounting bracket – despite being mounted on a
non-conductive material – is connected to metallic parts (even temporarily), you must ensure
that the appropriate potential equalization is provided between the switch cabinet and hous-
ing potential; e.g. by grounding the Ethernet connection.
8.2 Interfaces
The safety sensor has the following interfaces:
• Interface for connection with the control system
• Ethernet interface for communication with PC or laptop
• USB interface for communication with PC or laptop

NOTICE
Ä Use the USB connection only temporarily for configuration or diagnosis of the safety sensor.
Ä For permanent connection, connect the safety sensor to the Ethernet connection of the con-
nection unit.
The control cable is permanently attached to the connection unit. A protection cap on the connection unit
protects the communication interface when no PC is connected.
