Frequency inverter M-Max - Moeller

Operation04/10 MN04020001Z-ENOperational hazard warningsPlease observe the following notes.j Danger!Commissioning is only to be completed by qualifiedtechnicians.j Danger!Hazardous voltage!The safety instructions on pages I and II must be followed.j Danger!The components in the frequency inverter's power sectionare energized if the supply voltage (line voltage) isconnected. For instance: power terminals L1, L2/N, L3,R+, R-, U/T1, V/T2, W/T3.The control signal terminals are isolated from the linepower potential.There can be a dangerous voltage on the relay terminals(22 to 26) even if the frequency inverter is not beingsupplied with line voltage (e.g., integration of relaycontacts in control systems with 230 V AC).j Danger!The components in the frequency inverter's power sectionremain energized up to five (5) minutes after the supplyvoltage has been switched off (intermediate circuitcapacitor discharging time).Pay attention to hazard warnings!h Caution!Debounced inputs may not be used in the safetycircuit diagram.Any contactors and switching devices on the power sideare not to be opened during motor operation. Inchingoperation using the power switch is not permitted.Contactors and switching devices (repair andmaintenance switches) on the motor side must never beopened while the motor is in operation when thefrequency inverter is set to speed control operating mode(P11.8 = 1).Inching operation of the motor with contactors andswitching devices in the output of the frequency inverteris not permitted.h Caution!Debounced inputs may not be used in the safetycircuit diagram.Make sure that there is no danger in starting the motor.Disconnect the driven machine if there is a danger in anincorrect operational status.hhThe START button is only functional if the KEYPADoperating mode is activated.The STOP button is active in all operating modes. It can bedeactivated with parameter (P6.16 = 0).If motors are to be operated with frequencies higher thanthe standard 50 or 60 Hz, then these operating rangesmust be approved by the motor manufacturer. The motorscould be damaged otherwise.j Danger!Following a shutdown (fault, line voltage off), the motorcan start automatically (when the supply voltage isswitched back on) if the automatic restart function hasbeen enabled.(h parameter „P6.13“56
