OPERATING MANUAL

4.1 Connection guidelines

The following section contains some guidelines regarding the connections, which should be
followed to ensure the correct operation of the safety light curtain from the PSEN op2H-
A series.
• Never place connection cable close to or in contact with cables featuring high voltage
ratings and/or current fluctuations (e.g.: motor supply, inverters etc.).
• Never combine the OSSD wires from several safety light curtains into one multi-pole
cable.
• The TEST wire must be connected to the light curtain's operating voltage via a
pushbutton with N/O contact.
• Use the light curtain with protection class III with SEL/PELV external supplies for power
supply.
The RESET button must be positioned so that the user can check
the protected field during any test.
The RESET/RESTART/ALIGN button must be positioned so that the
user can check the protected field during all reset operations.
• The light curtain is already equipped with internal suppressors for overvoltage and
overcurrent. We would advise against using additional components.
