10.3. Removable Terminal Plug Connections
Please note the following points when making connections to the control input or output terminals
using the supplied removable terminal plugs:
• Do not tin stripped wire ends with solder. Soldered
wire ends will be crushed when the terminal plug
screws are tightened, leading to higher contact
resistance and potentially resulting in an abnormal
rise in the temperature of the connected parts.
• Use AWG 28 – 22 wire (ø0.32 – 0.64 mm solid wire
or multi-stranded wire with a cross- sectional area
of 0.08 – 0.32 mm
2
).
• Strip the wire end back about 7 mm (0.28").
• When connecting 2 wires or a signal cable to a
single terminal, crimp them in an insulated (twin)
wire ferrule to prevent their core wires from being
separated from one another. Use a ferrule of the
dimensions shown in the figure as below.
Note
b: 0.8–1.1 mm (0.03" – 0.04")
I2: 8 mm (0.31")
Select dimensions “a” and “l1”
depending on the wires to be
used.
