The frequency inverter must be earthed.Danger of electrical shock or fire.j Warning!Do not connect cables to the unmarked terminals in thepower section. Some of these terminals do not have afunction (dangerous voltages) or are reserved for DF51internal use.PEFigure 39:hPESConnecting cables to the power terminalsIn frame sizes DF51-…5K5 and DF51-…7K5 the PEconnection is located inside the enclosure.Connecting supply voltageX Connect the supply voltage to the power terminals:– Single-phase supply voltage: L, N and PE– Three-phase supply voltage: L1, L2, L3 and PE– DC supply and DC link coupling: DC+, DC– and PEX Tighten the cable connections according to a section“Tightening torques and conductor cross-sections for the powerterminals” page 217.X Refit the cable retainer. 139
