Round pressure terminal
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.
Connect same thickness
wiring to both sides.
- 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.
