following specifications (This equipment shall be provided with a cord set complying with the
national regulation).
If the supply cord is damaged, it must be replaced by a special cord or assembly available from

u Precautions when laying power and ground wiring
Use round pressure terminals for connections to the power terminal block.
When laying ground wiring, you must use round pressure terminals.
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.
