4 INSTALLATION AND WIRING
4.4.3 Wiring of connector
Specialised tools are not required for wiring the 24VDC power supply connector and
forced stop input connector because plugs with spring connection are used.
(1) Applicable wire size and wire fabrication
(a) Applicable wire size
The applicable wire size for 24VDC power supply connector and forced stop
input connector are shown below.
Connector Type Applicable wire size
24VDC power supply connector FKC-2.5/3-ST-5.08
0.3 t0 2.5mm

(AWG12 to AWG22)
Forced stop input connector FK-MCP1.5/3-ST-3.81
0.3 t0 1.5mm
2
(AWG16 to AWG22)
(b) Wire fabrication
Strip the wire according to stripped length indicated in the figure below.
Slide the sheath off the wire and gently twist and straighten the strands.
When using the wire, be careful not to short with stray strands entering the
neighbouring poles. Do not use solder on the wire's core as this may lead to
insufficient contact.

1) Using a ferrule
A ferrule can also be used to connect with the connector.
Use the ferrules in the table below for the 24VDC power supply
connector and forced stop input connector.

• Cut the wire sticking out from the end of the ferrule to 0.5mm
(0.02inch) or less.
0.5mm (0.02inch)

• When using a twin ferrule, be sure to insert the wire in a manner that
will keep the insulation sleeve from interfering with the neighbouring
poles. Be sure to crimp the ferrule.
