Technical data 401ACH550-01 User's ManualInput power (mains) cable, fuses and circuit breakersA four conductor cable (three phases and earth/protective earth)is recommended for the input power cabling. Shielding is notnecessary. Dimension the cables and fuses in accordance withthe input current. Always pay attention to local codes whensizing the cables and fuses.The input power connectors are at the bottom of the drive. Inputpower cable routing must be done so that the distance from thesides of the drive is at least 20 cm (8 in) to avoid excessiveradiation to the input power cable. In the case of shielded cable,twist the cable shield wires together into a bundle (pigtail) notlonger than five times its width and connect to the PE terminal ofthe drive (or PE terminal of input filter, if present).Line current harmonicsStandard ACH550 drive without any additional options meetsIEC/EN 61000-3-12 limits for harmonic currents. The standardcan be met with a transformer short circuit ratio of 120 or higher.The harmonic levels under rated load conditions are availableon request.FusesBranch circuit protection must be provided by the end-user,sized in accordance with the NEC and local codes.Recommendations for fuses for short-circuit protection on themains cable are in the following tables.Artisan Technology Group - Quality Instrumentation ...
