6.2 Checking the voltage of the auxiliary circuit transformer
The multi-voltage auxiliary circuit transformer has two primary windings (for 230 V and 400 V) or three primary windings (for
200, 208 and 460 V) and one secondary winding (24 V). The transformer is connected and checked in the factory, according
to the rated voltage. The transformer primary is protected by 10.3 x 38 mm cylindrical fuses on the disconnecting switch,
with the ratings indicated in Table 10.3.1.1.
6.3 Main control board
Version H
The auxiliary connections, which depend on the model and the controller, must be made by inserting the cables from the
outside into the electrical panel compartment using the smaller cable gland, located on the base of the humidifier until
reaching, through the channel in the internal partition, the removable screw terminal block located on the main control
board, as shown in Fig. 6.3.1 and described in the following paragraph:
