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 manual screwdriver instead of electric screwdriver for tightening the
terminal screws. A screwdriver with a small head will strip the head and make proper tightening
impossible.
- Over-tightening the terminal screws may break them.
WARNING
!
Make sure that the screws of the terminal are free from looseness.
