Connecting to the
frame When cables are routed from the unit, a
protection sleeve for the conduits (PG
insertions) can be inserted at the knockout
hole.
When you do not use a wire conduit,
protect the wires with vinyl tubes to
prevent the edge of the knockout hole from
cutting the wires.

3.6.2 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 mega­tester when measuring insulation.
▪ Do not use a mega­tester for low­voltage 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.
