Electrical connection
8.1
Electrical supply
see table 15.7.
Functional earth
• 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 figure 8.3).
• 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.
8.2
Interfaces
The safety sensor has two interfaces:
• Interface for connection with the control system
• Interface for communication with PC or laptop
WARNING
Faulty electrical connection or improper function selection may result in serious injury!
Only allow competent persons to perform the electrical connection.
For access guarding, activate the start/restart interlock and make certain that it cannot be unlocked
from within the danger zone.
Select the functions so that the safety sensor can be used as intended (see chapter 2.1 "Approved
Select the safety-relevant functions for the safety sensor (see chapter 5.2 "Function modes of safety
Always loop both safety-related switching outputs OSSD1 and OSSD2 into the work circuit of the
machine.
Signal outputs must not be used for switching safety-relevant signals.
NOTICE
Laying cables!
Lay all connection cables and signal lines within the electrical installation space or permanently in
cable ducts.
Lay the cables and lines so that they are protected against external damages.
For further information: see EN ISO 13849-2, Table D.4.
NOTICE
Always connect the housing of the safety sensor to functional earth or ground!
The housing of the safety sensor must always be connected to earth (functional earth) or machine/
vehicle ground.
If the safety sensor is attached to a non-conductive material (e.g. a concrete wall), the housing of the
safety sensor must be earthed.
NOTICE
Make sure that potential equalization is provided!
If the housing of the safety sensor or the mounting bracket – despite being mounted on a non-conduc
-
tive material – is connected to metallic parts (even temporarily), you must ensure that the appropriate
potential equalization is provided between the switch cabinet and housing potential; e.g. by grounding
the Ethernet connection.
