Wiring procedures
Procedures below are for the removable terminal plug with fixing screws.
Step 1. Loosen the terminal screw and insert the
cable lead.
Step 2. Tighten the screw.
Pull on the cable lead to ensure it is securely
connected.
If the lead pulls out, loosen the screw and
follow the above procedures again.
Step 3. Insert the terminal plug into the corresponding
terminal block in the unit's rear panel.
Note
Do not reverse Steps 1 – 2 and 3 above.
Force is applied to the connected receptacle pins
while tightening the terminal screw and they may be
damaged, resulting in bad connector contact.

Notes
• Do not use a micro screwdriver. Sufficient torque is not given to the screws when tightening them, and
connections may not be secured.
• 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.
