10.5. 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. Use the No. 4 ferrule terminal
when connecting 2 cables to a single terminal.
• Recommended ferrule terminals for all removable terminal plugs

• Connections to ferrule terminals
• Wiring procedures
Step 1. Connect the wire to 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.
Step 3 Tighten the fixing screws.
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.
