4. ELECTRICAL CONNECTIONS
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 humidi er power line must be tted, by the installer,
with a disconnecting switch and fuses protecting against short circuits.
Table 11.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.
