8. WIRING EXAMPLE AND HOW TO SET THE REMOTE CONTROLLER

8-1 WIRING EXAMPLE
Fit the power supply wiring of each unit with a switch and fuse as shown in the drawing.

Main switch
CAUTION
• When cramping wiring, use the included cramping material to do an appropriate cramp to prevent undue
pressure on the wiring connections. When carrying out the wiring, bundle the wires to prevent the switch
box lid from lifting, and attach the lid firmly. When attaching the switch box avoid getting wires caught always
use a wiring through-lid to prevent damage to the wires.
• Make sure to avoid external force to the field wiring(∗) such as by laying them in protection pipes or in the wall.
〈 〈 〈 〈 PRECAUTIONS〉 〉 〉 〉
1. Use ring-type crimp-style terminals for connecting wires
to the power supply terminal board. If unavailable,
observe the following points when wiring.
• Do not connect wires of different gauge to the same
power supply terminal. (Looseness in the connection
may cause overheating.)
• When connecting wires of the same gauge, connect
them according to the righthand figure.
• Use the specified electric wire. Connect the wire
securely to the terminal. Lock the wire down without
applying excessive force to the terminal. (Tightening
torque: 1.31N·m±10%)
2. Keep total current of crossover wiring between indoor units less than 12 A.
Branch the line outside the terminal board of the unit in accordance with electrical equipment standards,
when using two power wiring of a gauge greater than 2 mm
The branch must be sheathed 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.
