WARNING
ALWAYS use multicore cable for power supply cables.
INFORMATION
Also read the precautions and requirements in the "2 General safety
precautions" [ 4 10].
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 shocks.
▪
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, extension cords, or connections from a star system.
They can cause overheating, electrical shocks 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
Rotating fan. Before powering ON or servicing 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 80]
▪
"7.3.7 To remove the discharge grille, and put the grille in safety position" [
4
82]
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.
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.
9.1.2 Guidelines when connecting the electrical wiring
NOTICE
We recommend using solid (single-core) wires. If stranded wires are used, slightly
twist the strands to consolidate the end of the conductor for either direct use in the
terminal clamp or insertion in a round crimp-style terminal.
To prepare stranded conductor wire for installation
Method 1: Twisting conductor
1 Strip insulation (20 mm) from the wires.
