• All transmission wiring except for the remote control wires is polarized and must match the terminal symbol.
• Use screened wire in transmission wiring. Ground the shield of the shield wire to " ", at the grounding screw, with the C-cup washer.
• Sheathed wire materials may be used for transmission wiring, but they are not suitable for EMC (Electromagnetic Compatibility) (European
Directive).
• When using sheathed wire, electromagnetic compatibility must conform to Japanese standards stipulated in the Electric Appliance
Regulatory Act.
Transmission wiring need not be grounded when using sheathed wire.

PRECAUTIONS
!
1. Do not connect wires of different gauge to the same power
supply terminal. Looseness in the connection may cause
overheating. When connecting more than one wire to the
power supply wiring, use a 2 mm
Same gauge wires
2. Keep total current of crossover wiring between indoor units
less than 12 A. When using two power wiring of gauge greater
2
than 2 mm (φ 1.6), branch the line outside the terminal board
of the unit in accordance with electrical equipment standards.
The branch must be sheathed so as to provide an equal or
greater degree of insulation as the power supply wiring itself.
3. Do not connect wires of different gauge to the same
grounding terminal. Looseness in the connection may
deteriorate protection.
4. Keep the power supply wiring distant from other wires to
prevent noise.
5. For remote control wiring, refer to the "INSTALLATION
MANUAL OF REMOTE CONTROL".
