Precautions when laying power wiring
• Use sleeve-insulated round crimp-style terminals for connections to the power terminal strip.
If these are not available, see the following section.
When connecting wiring which is the same diameter, do as shown in the figure below.
Wiring of different thicknesses cannot be connected to the power terminal strip.
Stranded wires should be finished with solder and not used.
(Slack in the power wiring may cause abnormal heat.)
• For wiring, use the designated power wire and connect firmly, then secure using the included clamping
material to prevent outside pressure being exerted on the terminal board.
• Use an appropriate screwdriver for tightening the terminal screws.
A screwdriver of small size hurts its screw head, and cannot perform proper bolting.
• Over-tightening the terminal screw may break it.
See the table below for the tightening torque of the terminal screws.

Precautions when connecting the earth terminal

When pulling the earth wire out, wire it so that it comes through the cut-out section of the cup washer.
(An improper earth connection may prevent a good earth from being achieved.)
