6. INSTALLATION OF THE INTERNAL UNIT
6.6 Electrical supply
Electrical connections have to be done by qualified personnel, by observing
the current rules in the place where the air conditioner unit has to be
installed.
Electrical connection has to be preceded by a careful control about com-
patibility between the electrical supply line and the features of the unit
you want to connect.
In the electrical supply line of the unit it is mandatory to foresee a bipolar
switch (a differential one) with a contact separation of at least 3mm in
every pole.
Attention!
Before doing any work on the units, make sure that the main electrical
supply has been disconnected.
Before interrupting the power supply by means of the switch, turn the air
conditioner off with the remote control.
6.6.1 Preliminary checks
Check that the electric system providing the supply to the air conditioner has
voltage and frequency corresponding to the needs of the unit.
Check that the electrical power available to the user is sufficient for the air
conditioner and the other electrical appliances to work.
6.6.2 Power supply of the units
For al models, power supply is moved to external unit.

- Use a multi-pole cable of type N07RN-F
- For lengths over 15m., use the next higher standard section, always
checking that in every case the voltage drop during operation is lower
than 3% of the supply voltage.
- If a cable is damaged it must be replaced by service personnel or by
qualified personnel.
- All cables must have the certificate of conformity.
6.6.4 Connection to the terminal board
