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, 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.
