For terminal assignments, please consult the appropriate module data sheet.
Follow these steps when wiring:
▪
Strip 8mm (0.3in.) off the cable. Module wiring is normally done without
ferrules. However, it is possible to use ferrules. If using ferrules, make sure
they are properly crimped.
▪
Push a screwdriver into the slot for the appropriate connection (#

above) so
that you can plug the wire into the spring opening.
▪
Insert the wire (#2 above). Pull the screwdriver out of the opening. The wire is
clamped.
After installation, you should label the wires and Terminal Strips as described later
in this chapter.
