4.1. Notes on connections
For the correct functioning of the SG2 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 ESPE.
The RESET/RESTART wire must be connected through a N.O. button to the supply voltage of the
ESPE.
The RESET/RESTART button must be located in such a way that the operator can check the
protected area during any test (see chapter 6 “Functioning mode”).
The device is protected internally against overvoltage and overcurrent: the use of other outer parts
is not recommended.
