5.2 Important notes on connections
For the correct functioning of the Orion3 Base light grids, the following precautions regarding the electrical
connections have to be respected:

The Orion3 Base light grids shall be connected as protective class III equipment and the use of a SELV/PELV
supply system is mandatory. A functional earth is available on pin 8 of the M12 connector (red wire). It can be
connected or left floating depending on the application.

Do not place connection cables in contact with or near high-voltage cables and/or cables undergoing high
current variations (e.g. motor power supplies, inverters, etc.).

Do not connect the OSSD wires of different AOPDs in the same multi-pole cable.

The device is already equipped with internal overvoltage and overcurrent suppression devices. The use of
other external components is not recommended.
Warning! The RESET/ACKNOWLEDGE button must be located in such a way that the operator can check the entire
hazard zone during any Reset operation (see paragraph 7
– “Functions”).
