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.

Round pressure terminal
It is forbidden to
connect two to one
side.
It is forbidden to
connect wiring of
different thicknesses.
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.

indoor and outdoor unit should be
complied with the following specifications
(This equipment shall be provided with a
