50/60 Hz
±10% 0.75 mm² ↑, 3 wires
Communication cable
0.75 mm², 2 wires
NOTE
• Power supply cords of parts of appliances for outdoor

– Code designation
– [1-phase] IEC: 60245 IEC 57 / CENELEC: H05RN-F

grade or more
• When installing the indoor unit in a computer room
or net work room, use the double shielded (tape
aluminium / polyester braid + copper ) cable of
FROHH2R type.
CAUTION
• Use rated cables or products only, with heat resistance
over 105°C, as well as properly rated switches or fuses
in the cabinet panel.
• Make sure that the cables connected do not produce
sparks around the auxiliary power switch or that they
are not installed in a place subject to high temperature.
High ambient temperature decreases allowable
current.
• Install the auxiliary power switch in a dry place, install
the panel board or electrical component box, and then
install the circuit breaker in the panel board.
• When connecting the main power cable, press the cable
to the terminal for a secure connection.
• Select a ring terminal for use.

Connecting the cable to the power terminal
Connect the cables to the terminal board with the ring
terminals.
NOTE
• Be sure to use the certified and rated cables and firmly
connect them without applying any external force to
the ring terminal.
• Connect with a driver and wrench that can apply the
rated torque to the screws.
• Connect the terminal screws in compliance with the
rated tightening torques.
• If the terminal is loose, a fire may occur, caused by
arcing electricity. If the terminal is connected too
firmly, the terminal may be damaged.
