NOTICE
Precautions when laying power wiring:
▪ Do NOT connect wiring of different thicknesses to the power terminal block (slack
in the power wiring may cause abnormal heat).
▪ When connecting wiring which is the same thickness, do as shown in the figure
above.
▪ For wiring, use the designated power wire and connect firmly, then secure to
prevent outside pressure being exerted on the terminal board.
▪ Use an appropriate screwdriver for tightening the terminal screws. A screwdriver
with a small head will damage the head and make proper tightening impossible.
▪ Over-tightening the terminal screws may break them.
Install power cables at least 1 meter away from televisions or radios to prevent
interference. Depending on the radio waves, a distance of 1 meter may NOT be
sufficient.
NOTICE
ONLY applicable if the power supply is three‑phase, and the compressor has an ON/
OFF starting method.
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.
