It must be verified that electric supply is corresponding to the unit electric nominal data
(tension, phases, frequency) reported on the label in the front panel of the unit.
Power connections must be made using a three-wire cable + neutral wire + ground cable.
Ground connection is compulsory. Installer must connect ground cable with a dedicated terminal on
the apposite terminal block.
Close to the unit a main switch must be present.
Power cable and line protection must be sized according norm and laws according
with absorbed current of the machine (see technical data).
The line voltage fluctuations must not be more than ±5% of the nominal value, while
the voltage unbalance between one phase and another must not exceed 2%. If those
tolerances should not be respected, please contact our Firm to provide proper
devices.
Electric supply must be in the limits shown: in the opposite case warranty will
terminate immediately.
Electrical connections therefore must be always done according to the instructions
reported on the wiring diagram enclosed with the unit and norms and laws.
