Ariston COMPACT M NET R32 Technical Instructions For Installation page 32

The cross-sectional size of the cables used must comply with the system power (see data plate).
The cross-sectional size of the power cables indicated in the table must be regarded as the minimum cross-sectional -size.

Prior to accessing the terminals, all the supply circuits must be disconnected.

The power supplies of the indoor and outdoor units must be connected respectively to a dedicated residual-current circuit break-
er (RCCB) with a minimum threshold of 30 mA. For units equipped with an inverter (outdoor unit), we recommend using type B
residual-current devices for 3 ph power supplies and type B or F devices (depending on the electrical system to which they are
connected) for 1 ph power supplies. For units lacking an inverter (indoor unit), a type A residual-current device will suffice. The type
of connection must nonetheless be made in a workmanlike manner by qualified personnel in order to comply with the national
regulations in force.

Note: in making the connection between the communication cable from the indoor unit to the outdoor unit, use a shielded cable
to prevent interference problems.
