power cable inlet;
2.
optional utility cable inlet (after drilling).
3.
probe cable inlet. On models UE001 to UE018, remove the plastic “tab”
and use it to secure the cable (held in place by the screws provided).
4.2 Power cable connection
Before making the connections, ensure that the machine is
disconnected from the mains power supply.
Check that the power supply voltage of the appliance corresponds to
the value indicated on the rating plate inside the electrical panel.
Insert the power and ground connection cables into the electrical panel
compartment using the tear-proof cable gland supplied, or through the
cable gland with cable stop, and connect the ends to the terminals (see
Fig. 4.c). The humidifi er power line must be fi tted, by the installer, with a
disconnecting switch and fuses protecting against short circuits.
Table 12.a lists the recommended cross-sections of the power supply
cable and the recommended fuse ratings; note, however, that this data is
purely a guide and, in the event of non-compliance with local standards,
the latter must prevail.
Note:
to avoid unwanted interference, the power cables should be kept
apart from the probe signal cables.

Important:
connect the yellow-green cable to the earth point (PE).
4.3 Control signals ( M2.1 - M2.8; M7.1 - M7.2)
Steam production by the humidifi er is enabled or controlled.
For connection of control signals, use the connection kit (supplied in the
packaging) and run the cables from the humidifi er through the cable
gland (Fig. 4.a or 4.b).
Depending on the type of signal used, steam production can be enabled
and/or managed in diff erent ways.
1. Enable steam production using:
REMOTE CONTACT (ON/OFF action)
•
jumper outputs M7.1 and M7.2
•
connect outputs M2.7 and M2.8 to a remote contact (e.g.: switch,
timer,…).
