Power wire
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.
