3.5.1 Spring connector
The product is delivered with spring connectors. To connect a wire it is first of all necessary to strip it on
4mm then using a screwdriver to press on the strip to give off the blade. To then insert the son in the
terminal and to slacken the pressure on the strip so that the blade imprisons the son and makes contact.
The connection of the cables is identical for the detectors and actuators.
The acceptable section of wire goes from 0,14 to 1,5mm².
