e P-clamp for cable shield earthing
Fix to the indicated plastic brackets using field supplied clamping
material.
The indoor F1/F2 interconnection wiring MUST be shielded wire.
The shielding is earthed via a metal P-clamp (e) (only at outdoor
unit). Strip the insulation up to the shielding mesh, to provide full
contact of the earth with the shielding.
17.4 To connect the interconnection
wiring
The wiring from the indoor units must be connected to the F1/F2
(In‑Out) terminals on the PCB in the outdoor unit.
See "17.2 Specifications of standard wiring components" [4 37] for
wiring requirements.

d Outdoor unit/other system interconnection (F1/F2)
▪ The interconnecting wiring between the outdoor 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 outdoor unit to which the
interconnecting wiring for the indoor units is connected.
▪ The base unit is the outdoor unit to which the interconnecting
wiring for the indoor units is connected.

17.5 To finish the interconnection
wiring
After installing the interconnection wiring, wrap it along with the
onsite refrigerant piping using finishing tape, as shown in the

17.6 To route and fix the power supply
NOTICE
When routing earth wires, secure clearance of 25 mm 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 earth.
The power supply wiring can be routed from the front and left side.
Fix it to the lower mounting hole.
