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.

The connecting cable connected to the
indoor and outdoor unit should be
complied with the following specifications
(This equipment shall be provided with a

Connect same thickness
wiring to both sides.
It is forbidden to
connect two to one

It is forbidden to
connect wiring of
different thicknesses.
- 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.
