The power supply line must be protected against short-circuit.
If both internal and external units are requested to be supplied without main switches, the contractor
installing the equipment must fit main switches near both the internal and external units (in accordance
with the safety norms current in the country where the units are installed).
The A/C units and the condensers are supplied with earth terminals and these must be correctly
earthed in order to avoid possible accidents.
Check the electrical wiring diagrams for correct wiring between indoor and outdoor units.
The contractor installing the equipment must verify that the supply power corresponds to that which is
indicated on the identification plate of the A/C unit as well as on the electrical diagrams supplied.
