6.3 Power supply
• Check that the power supply voltage of the appliance corresponds to
the value indicated on the rating plate.
• Connect the 50 Vac transformer output to terminals 1 and 5 on
connector B;
• Connect the 24 Vac transformer output to the terminals on connector A;
• Connect the transformer input cable to the mains. The humidier
power line must be tted with a disconnect switch.
NOTICE: to avoid unwanted interference, the power cables should be
kept separate from the probe signal cables.
Once the electrical and water connections have been completed, the
humidier is ready for operation.
