• 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 terinal screws. A screwdriver with a small head
will strip the head and make proper tighterning 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.
