To connect the transmission wiring

The wiring from the indoor units must be connected to the F1/F2
(In-Out) terminals on the PCB in the outside unit.

▪ The interconnecting wiring between the outside units in the same
piping system must be connected to the Q1/Q2 (Out Multi)
terminals. Connecting the wires to the F1/F2 terminals results in
system malfunction.
▪ The wiring for the other systems must be connected to the F1/F2
(Out-Out) terminals of the PCB in the outside unit to which the
interconnecting wiring for the indoor units is connected.
▪ The base unit is the outside unit to which the interconnecting
wiring for the indoor units is connected.

To route and fix the power supply

NOTE
When routing ground wires, secure clearance of 1 inch or
more away from compressor lead wires. Failure to observe
this instruction properly may adversely affect correct
operation of other units connected to the same ground.
The power supply wiring can be routed from the front side. Exit the
wiring via the upper mounting hole.

To connect the power supply

NOTE
Never connect the power supply to transmission wiring
terminal block. Otherwise the entire system may break
down.
