WARNING
▪ All wiring MUST be performed by an authorised electrician and MUST comply
with the applicable legislation.
▪ Make electrical connections to the fixed wiring.
▪ All components procured on-site and all electrical construction MUST comply
with the applicable legislation.
WARNING
Electrical wiring connection method MUST be in accordance with the instructions
from this manual. See "20Electrical installation"[4101].
WARNING
ALWAYS use multicore cable for power supply cables.
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 in the unit.
