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.
WARNING
▪
After finishing the electrical work, confirm that each electrical component and
terminal inside the electrical components box is connected securely.
▪
Make sure all covers are closed before starting up the unit.
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.
