INSTALLATION
Preliminary operations
Remove the appliance from the packaging, ensure that it is intact and, if in doubt, do not use it but
contact professionally qualified personnel. The packaging materials are compliant with
environmental safety regulations. They can be stored without risk, or else should be disposed of in
accordance with current national regulations, particularly those regarding the nylon bag and the
polystyrene.
After verifying that the appliance is in good conditions, the protective film may be removed. Clean
the external parts of the appliance carefully with warm water and detergent, using a cloth to remove
all remaining residues and then dry it with a soft cloth. If there are still traces of glue, these can be
removed using a suitable solvent (e.g. acetone). Under no circumstances should abrasive substances
be used. After the installation the appliance should be levelled by lowering or raising the adjustable
legs.
Electric connection
Before connecting the appliance, it is necessary to check that the voltage of the power supply
available corresponds to the voltage the appliance has been set for. In the event that they do not
correspond, it is necessary to modify the connection as shown in the electric diagram, if voltage
change is provided for. The terminal blocks are situated behind the instrument board and they can
be removed unscrewing the 2 screws that fix the support. Before connecting the cable to the
terminal blocks, it is necessary to let it pass through the cable gland (fig. 2 at page 2).
If the supply
cord is damaged, it must be replaced by the manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard.
Furthermore, the efficiency of the earth connection must be checked, and also that the earth
conductor on the connecting side is longer than the other conductors, and that the connecting cable
has a wire bunch adequate for the power absorbed by the appliance and is at least type H05 RN-F.
As in international provisions, before installing the appliance a unipolar device must be
installed with a contacts opening of at least 3mm which must not interrupt the YELLOW-
GREEN earth wire.
The device must be installed near the appliance, it must be approved and have
adequate capacity for the absorption of the appliance (see technical features).
The appliance must be connected to the EQUIPOTENZIALE system. The connector is situated near
the end of the electric cable and is identified by a label with the symbol shown on figure 6 (page. 3).
When using a safety switch for fault currents, the following should be observed:

According to current legislation, this kind of appliances can have a leakage current of 1mA
per kW of rated power input with no maximum. It should also be noted that all fault current
