Electric wiring
Connection of wiring
Connect the wires in accordance with the diagram of each
system.
All wiring must be performed by an authorized electrician.
All field supplied parts and materials and electric works must
conform to local regulations.
Use copper wire only
Connection of wiring
A main switch or other means for disconnection, having a
contact separation in all poles, must be incorporated in the fixed
wiring in accordance with applicable legislation.
Do not turn on the main switch until all the wiring is completed.
A single switch can be used to supply power to units on the
same system. However, branch switches and branch circuit
breakers must be selected carefully.
Fit the power supply wiring of each unit with a switch and fuse as
shown in the drawing.
Be sure to make the electric grounding (earth) connection.

Precautions
1
Do not connect wires of different gauge to the same power
supply terminal. Looseness in the connection may cause
overheating or electric malfunction.
When connecting more than one wire to the power supply
wiring, use a 2 mm
2
(Ø1.6) gauge wire.
When using two power wires of a gauge greater than 2 mm
2
(Ø1.6), 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 a degree of
insulation equal to or greater than the power supply wiring itself.
2
Keep total current of crossover wiring between indoor units less
than 12 A.
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 controller wiring, refer to the Installation manual of
the remote controller.
Before obtaining access to terminal devices, all power
supply circuits must be interrupted.
