9.2. POWER SUPPLY

All fan coil units are designed for operation under 230 volts, single phase, 50 or 60 cycles .
A voltage variation of ± 10 % with regard to nominal voltage 230 V is acceptable.
Note: The Model 70 is not available in 60 Hz.

IMPORTANT

Short circuit protection shall be provided. This protection shall comprise fuses or circuit breakers with high breaking
capacity, mounted on the distribution board.
² Fuse available as an option
² Cable not supplied
9.3. ELECTRICAL CONNECTIONS
The electrical installation must be performed by a fully qualified electrician, and in accordance with local electrical
standards and the wiring diagram corresponding to the unit model.
Any modification performed without our prior authorisation may result in the unit's warranty being declared null
and void.
The power supply cable section must be sufficient to provide the appropriate voltage to the unit's power supply
terminals, both at start-up and under full load operating conditions.
Before making the connections, be sure that the available power supply has the same voltage and phase as that
shown on the fan coil unit nameplate.
Line and low voltage wiring must be done in accordance with electrical code whichever is applicable. Earthing of
unit is imperative.
Manufacturer or its representative cannot be held responsible for accidents resulting from incorrect
or non-existent earthing.
A device to disconnect all the power conductors with an approved minimum opening distance must be included
in the mains power supply according to best installation practices.
To perform electrical wiring of the unit, please refer to the wiring diagram pasted on
BEFORE CARRYING OUT ANY WORK ON THE EQUIPMENT,
MAKE SURE THAT THE ELECTRICAL POWER SUPPLY IS
DISCONNECTED AND THAT THERE IS NO POSSIBILITY
OF THE UNIT BEING STARTED INADVERTENTLY.
NON-COMPLIANCE WITH THE ABOVE INSTRUCTIONS
CAN LEAD TO INJURY OR DEATH BY ELECTROCUTION.
