8-4 WIRING CONNECTION METHOD
<<Caution for wiring>>
• The indoor units in the same system can be connected to the power supply from one branch switch. How-
ever, selection of branch switch, branch over current circuit breaker and wiring size must be according to
applicable legislation.
• For connection to the terminal block, use ring type crimp style terminals with insulation sleeve or treat the
wiring with insulation.
• If the above is not available, make sure to observe the following items.
• 2 wirings of different sizes to the terminal block for power supply is prohibited.
Connection of 2 wirings
of same size must be
carried out on both sides.
(Abnormal heating may occur if the wirings are not tightened securely.)
• Use the required wirings, connect them securely and fix these wirings so that external force may not apply
to the terminals.
• Use a proper screw driver for tightening the terminal screws. If an improper screw driver is used, it may
damage the screw head and a proper tightening cannot be carried out.
• If a terminal is over tightened, it may be damaged. Refer to the table shown below for tightening torque of
terminals.

• Conduct wiring so that the earth lead comes out from the notched part of the cup washer. (Otherwise, earth
lead contact will be insufficient and grounding effect may be lost.)
• Do not carry out soldering finish when stranded wirings are used.
