The power supply cable must be connected to a 230V ±10% / 50Hz mains supply
respecting L-N polarity and earth connection; this network must also have a multi-
pole circuit breaker with class III overvoltage category in compliance with
installation regulations.
To protect from possible dispersions of DC voltage, it is necessary to provide a type A
differential safety device.
If the power cable is damaged, contact a qualified company (e.g. the Authorised
Technical Assistance Centre) for its replacement to avoid a hazard.
The power supply cable must be laid as shown (Par. 1.9); avoiding any contact with the side of the frame.
If the fuses on the circuit boards need to be replaced, this must also be done by qualified personnel: use a F3.15A H250V fuse on the P.C.B.
For the main power supply to the appliance, never use adapters, multiple sockets or extension leads.
Make the various electrical connections according to your needs (Fig. 13, 14);
Connect the relative terminals 37 and 38 to electrically connect the Indoor Unit and the storage tank unit, removing heating
element R8 in the instrument (Fig. 13):
Outdoor Unit electrical connection
The Indoor Unit must be coupled to an Outdoor Unit by connecting terminals F1 and F2 as shown in the wiring diagram (Fig.14).The In-
door Unit is powered at 230 V, regardless of the Outdoor Unit.
Configure the Indoor Unit parameters as indicated in paragraph (Parag.3.9).
Photovoltaic system installation
Connecting the product to a photovoltaic system enhances use of the Outdoor Unit when the photovoltaic panels are operating. Carry
out the connection as indicated (Fig.13).
Dehumidifiers
Carry out the connection as indicated (Fig.14). To complete the connection operations, insert the 2-relay Board optional kit.
It is compulsory to set up separate lines with different power supply voltages,
particularly it is essential to separate the very low voltage connections from the 230 V
ones.
No product pipes must ever be used to earth the electric system or telephone lines.
Ensure elimination of this risk before making the Indoor Unit electrical
connections.
The Indoor Unit can be electrically connected to outdoor units with very low voltage
safety circuits (SELV)
