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.

Round pressure terminal
- 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.
