ELECTRICAL CONNECTIONS
RECOMMENDATIONS!
Before carrying out electrical connections, ensure that the electricity
supply to the supply line has been cut off, checking that the on-off
switch is in the OFF position. Only qualifi ed electricians should carry
out the electrical connections. Check that the mains supply is single-
phase 230 Vac/1/50 Hz (± 10%).
Operating the appliance with voltages outside the above limits could
cause malfunction and renders the warranty null and void.
The fan coil power supply line should be fi tted with at least a switch
isolator in conformity with European standard EN60947-3. Make sure
that the electrical system is suitable for providing not only the working
current required by the appliance, but also the necessary current for
powering household and other electrical appliances already in use.
Any electrical and mechanical alterations or tampering render the warranty null and void. The motor and accessories power cables in channels
or ducts should remain inside the same until they are inside the appliances.
The cables should be suffi ciently long so that they are not permanently taut or create throttling or pressure on metal parts (see Pic. 16). The
power cables should be suffi ciently long so that in the event of accidental tugging the active wires are subjected to stress before the earth wire.
Connect the earth wire to the relative terminal marked with the symbol .
Check the earth connection. Comply with the safety regulations in force in the country of installation.
CONNECTIONS TO THE TERMINAL BOARD
WITHOUT CONTROL PANEL
The electrical connections should be made to the terminal board on the side of the appliance.
Each terminal is identifi ed by the label to be found on the terminal board.
WITH CONTROL PANEL
The electrical connections should be made directly to the control panel, as shown by the relative wiring diagram. If the control panel has an
electronic temperature sensor (NTC) this sensor will be powered by mains voltage (230Vac/1/50 Hz) and is therefore provided with double
insulation.
CAUTION: FAILURE TO COMPLY WITH THE INDICATED CONNECTIONS MAY CAUSE MOTOR BURNOUT!
