5.3 Important notes on connections
For the correct functioning of the Orion1 Base light curtains, the following precautions regarding the electrical
connections have to be respected:
Use a suitably insulated low-voltage supply system type SELV or PELV.
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 TEST wire must be connected to the supply voltage of the AOPD through a NO push-button.
The ACKNOWLEDGE/RESET wire must be connected through a NO push-button to the supply voltage of the
Orion1 Base light curtain.
Warning!
The TEST button must be located in such a way that the operator can check the hazard zone during any
test (see paragraph 7
– “Functions”.)
Warning!
The ACKNOWLEDGE/RESET button must be located in such a way that the operator can check the hazard
zone during any reset operation (see paragraph 7
– “Functions”.)
The device is already equipped with internal overvoltage and overcurrent suppression devices. The use of
other external components is not recommended.
