Transmission wiring
• For multi system:
1
Transmission wiring between outdoor units in the same piping
system must be connected to terminals X4 and X5.
Connecting the wires to the X2, X3 terminals results in system
malfunction.
2
Wiring to other systems should be connected to terminals X2 and
X3 on the printed circuit board of the master unit. The outdoor unit
that connects transmission wiring to indoor unit is the master unit.
The others are sub unit.
9.5. Power wiring connection procedure
• Be sure to connect the power supply wiring to the power supply ter-
minal block, pass each phase (L1- 3) wire through separate rubber

• Fix the ground wiring with the included clamp by taking care not to
apply external pressure on the terminal area.
• Pass the power supply wiring and ground wiring through their
respective rubber sleeve and fix with the included clamps to prevent
