Securely attach the electrical
part cover to the indoor unit
and the service panel to the
outdoor unit.
•
If the electrical part cover of the indoor
unit and the service panel of the out-
door unit are not attached securely, it
could result in a fire or electric shock
due to dust, water, etc.
Ensure a dedicated circuit
breaker is installed as well as
an independent electrical dis-
connect.
• No installation may cause a fire

Wiring Connection
Installation Manual 9
ENGLISH
• For wiring, use the designated power wire and connect firmly, then secure to prevent outside pres-
sure being exerted on the terminal block.
• Use an appropriate 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.
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.
◆
Precautions when laying power wiring
Round pressure terminal Power wire
Use round pressure terminals for connections to the power terminal block.
