For the correct functioning of the PSEN op4F/H-s safety light
curtains, the following precautions regarding the electrical
connections have to be respected:
•
Do not place connection cables in contact with or near high-voltage
cables and/or cable undergoing high current variations (e.g. motor
power supplies, inverters, etc.);
•
Do not connect in the same multi-pole cable the OSSD wires of
different light curtains;
•
The TEST wire must be connected through a N.O. button to the
supply voltage of the AOPD. The TEST function is optional for the
safety light curtains Type 4.
•
The RESET/RESTART wire must be connected through a N.O.
