24.2. Removable Terminal Plug Connection
Notes
• Avoid soldering stranded or shielded cable, as contact resistance may increase when the cable is tightened
and the solder is crushed, possibly resulting in an excessive rise in joint temperatures.
• When connecting 2 cables or a shielded cable to a single terminal, use a ferrule terminal with an insulation
sleeve to crimp the cables because such cable conductors could become loose.

Wiring procedures
Step 1. Wiring the supplied removable terminal
plug.
1-1. Loosen the terminal screws to insert
the wire.
1-2. Tighten the terminal screws.
Ensure that the wire does not break
free when pulled. If the wire does pull
free, repeat the connection procedure
from the start.
Step 2. Insert the wired terminal plug into the
corresponding terminal block in the
unit’s rear panel.
Note
Do not reverse Steps 1 and 2 above. Force is
applied to the connected receptacle pins while
tightening the terminal screw and they may be
damaged, resulting in bad connector contact.
