◆ Precautions when laying power wiring
Use round pressure terminals for connections to the power terminal block.
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.
• For wiring, use the designated power wire and connect firmly, then secure to prevent outside pressure
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.
