4.1. Notes on connections
For the correct functioning of the SG4 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 TEST button must be located in such a way that the operator
can check the protected area during any test (see section 6
“Functioning mode”).
The RESET/RESTART button must be located in such a way that the
operator can check the protected area during any reset operation
(see section 6 “Functioning mode”).
 The device is already equipped with internal overvoltage and
overcurrent suppression devices. The use of other external
components is not recommended.
