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.
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.
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.
