Power supplies of the indoor and the outdoor units are to be respectively connected to a Residual Current operated Circuit-Breaker
(RCCB) with threshold of 30mA. For inverter driven units (outdoor unit), It is advisable the use of type B residual current device for 3Ph
power supplies and type B or F for 1Ph power supplies (depending on the electrical system to which it is connected). For the units
without inverter, (indoor units) a type A Residual current device is sufficient. The type of connection must in any case be carried out in
a workmanlike manner by qualified personnel in compliance with the national regulations in force.
