ENGLISH

• For wiring, use the designated power wire and connect firmly, then secure to prevent outside pres-

sure being exerted on the terminal block.

• Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head

will strip the head and make proper tightening impossible.

• Over-tightening the terminal screws may break them.

When none are available, follow the instructions below.

• Do not connect wiring of different thicknesses to the power terminal block. (Slack in the power

wiring may cause abnormal heat.)

• When connecting wiring which is the same thickness, do as shown in the figure below.

◆

Precautions when laying power wiring

Round pressure terminal Power wire

Use round pressure terminals for connections to the power terminal block.
