15.7 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.

small animals or dirt from entering.
15.8 To connect the power supply
The power supply MUST be clamped to the plastic bracket using
field supplied clamp material to prevent external force being applied
to the terminal. The green and yellow striped wire MUST be used for
earthing only.

Multiple outdoor units
To connect the power supply for multiple outdoor units to each other,
ring tongues have to be used. No bare cable can be used.
In that case, the ring washer that is installed by default should be
removed.
Attach both cables to the power supply terminal as indicated below:

15.9 To check the insulation resistance
of the compressor
NOTICE
If, after installation, refrigerant accumulates in the
compressor, the insulation resistance over the poles can
drop, but if it is at least 1 MΩ, then the unit will not break
down.
▪ Use a 500 V mega-tester when measuring insulation.
▪ Do NOT use a mega-tester for low voltage circuits.
1 Measure the insulation resistance over the poles.
If Then
≥1 MΩ Insulation resistance is OK. This procedure
is finished.
<1 MΩ Insulation resistance is not OK. Go to the
next step.
2 Turn ON the power and leave it on for 6 hours.
Result: The compressor will heat up and evaporate any
refrigerant in the compressor.
3 Measure the insulation resistance again.
