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.
WARNING
If the supply cord is damaged, it MUST be replaced by the manufacturer, its service
agent or similarly qualified persons in order to avoid a hazard.
WARNING
ALWAYS use multicore cable for power supply cables.
WARNING
Rotating fan. Before powering ON the outdoor unit, make sure that the discharge
grille covers the fan as protection against a rotating fan. See "7.3.6 To install the
discharge grille"[486].
CAUTION
Do NOT push or place redundant cable length into the unit.
WARNING
The backup heater MUST have a dedicated power supply and MUST be protected by
the safety devices required by the applicable legislation.
CAUTION
If the indoor unit has a tank with a built‑in electrical booster heater, use a dedicated
power circuit for the backup heater and booster heater. NEVER use a power circuit
shared by another appliance. This power circuit MUST be protected with the
required safety devices according to the applicable legislation.
CAUTION
To guarantee the unit is completely earthed, ALWAYS connect the backup heater
power supply and the earth cable.
