Precautions when laying power wiring
When none are available, follow the instructions below.
• 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 terminal screws. A screwdriver with a small head will strip the
head and make proper tighterning impossible.
• Over-tightening the terminal screws may break them.
CAUTION
When the 400 volt power supply is applied to “N” phase by mistake, replace inverter PCB and transformer
in control box.
Use round pressure terminals for connections to the power terminal
block.
