WARNING
The reversed phase protection detector of this
product only functions when the product starts up.
Consequently reversed phase detection is not
performed during normal operation of the product.
The reversed phase protection detector is designed to
stop the product in the event of an abnormality when
the product is started up.
Replace two of the three phases (L1, L2, and L3)
during reverse-phase protection abnormality.
If there exists the possibility of reversed phase after a
momentary black out and the power goes on and off
while the product is operating, attach a reversed
phase protection circuit locally. Running the product in
reversed phase can break the compressor and other
parts.
