WARNING
▪
If the power supply has a missing or wrong N-phase, equipment might break
down.
▪
Establish proper earthing. Do NOT earth the unit to a utility pipe, surge absorber,
or telephone earth. Incomplete earthing may cause electrical shock.
▪
Install the required fuses or circuit breakers.
▪
Secure the electrical wiring with cable ties so that the cables do NOT come in
contact with sharp edges or piping, particularly on the high-pressure side.
▪
Do NOT use taped wires, stranded conductor wires, extension cords, or
connections from a star system. They can cause overheating, electrical shock or
fire.
▪
Do NOT install a phase advancing capacitor, because this unit is equipped with an
inverter. A phase advancing capacitor will reduce performance and may cause
accidents.
CAUTION
Do NOT push or place redundant cable length into the unit.
NOTICE
The distance between the high voltage and low voltage cables should be at least
50 mm.
Keep the following in mind:
▪
If stranded conductor wires are used, install a round crimp-style terminal on the
end of the wire. Place the round crimp-style terminal on the wire up to the
covered part and fasten the terminal with the appropriate tool.
