Tolerance allowed on the nominal mains voltage: -15% +10%
Tolerance allowed on the nominal mains frequency: ± 1 %.
(2)
Recommended values; referred to cables laid in closed PVC or rubber conduits 20 m long.
(3)
Instant steam production: average steam production may be aff ected by external factors, such as: ambient temperature,
water quality, steam distribution system.
Notice:
the power cable must be sized in compliance with the local regulations in force. The humidifi er power supply line
must be equipped with an disconnect switch and protection fuses suitably sized for the short-circuit current, to be fi tted by the
installer.
Notice:
on the outdoor models, the heaters, where featured, must have its own independent power supply line, not
shared with the humidifi er.
9.1.4
A
uxiliary circuit transformer
The multi-voltage auxiliary circuit transformer has a primary winding for 230 V (protected by fuses, 10.3x38 mm) and a secondary
winding (24 V). The transformer is connected and checked in the factory, according to the rated voltage.
9.1.5 Main control board
The auxiliary connections must be made by inserting the cables into the electrical panel compartment through the cable glands
on the side (1 - Fig. 9.i) or on the bottom of the humidifi er (2 - Fig. 9.a, UL outdoor versions only). It is recommended to secure the
probe, remote ON/OFF contact connection cables etc. with appropriate cable ties, in order to prevent disconnection.
