7.8 ELECTRICAL CONNECTIONS
Check out that the power supply meets the unit’s electric nominal data (tension, phases, frequency) reported on the label in the
unit’s side panel. Power connections have to be made in accordance to the wiring diagram enclosed with the unit and in
conformity with the national and international norms in force (providing equipment as general magnetothermic circuit breaker,
differential circuit breakers for each electric line, proper grounding for the plant, etc.). Power cables, electric protections and line
fuses have to be sized according to the specifications listed in the wiring diagram enclosed with the unit and in the electrical data
contained in the table of technical characteristics (see Paragraph 12).
