What F30011 means

Line phase failure in main circuit p. 300

Common causes

  • At the power unit, the DC link voltage ripple has exceeded the permissible limit value. p. 300
  • Possible causes: A line phase has failed. p. 300
  • The 3 line phases are inadmissibly unsymmetrical. p. 300
  • The fuse of a phase of a main circuit has ruptured. p. 300
  • A motor phase has failed. p. 300

Safety warnings — read before you start

  • DANGERGeneral Safety Instructions. Qualified Personnel The product/system described in this documentation may be operated only by personnel qualified for the specific task in accordance with the relevant documentation, in particular its warning notices and safety instructions. p. 2
  • WARNINGRisk of Electric Shock and Fire. Risk of electric shock and fire from supply networks with an excessively low impedance Excessively high short-circuit currents can lead to the protective devices not being able to interrupt these short-circuit currents and being destroyed, and thus causing electric shock or a fire. p. 12
  • WARNINGElectric Shock if No Ground Connection. Electric shock if there is no ground connection For missing or incorrectly implemented protective conductor connection for devices with protection class I, high voltages can be present at open, exposed parts, which when touched, can result in death or severe injury. p. 12
  • WARNINGElectric Shock Due to Unsuitable Power Supply. Electric shock due to connection to an unsuitable power supply When equipment is connected to an unsuitable power supply, exposed components may carry a hazardous voltage that might result in serious injury or death. p. 12

What to do

  1. Check the main circuit fuses. p. 300
  2. Check whether a single-phase load is distorting the line voltages. p. 300
  3. Check the motor feeder cables. p. 300

If F30011 is still not resolved

  • Contact service / dealer for assistance p. 2
    “Qualified Personnel The product/system described in this documentation may be operated only by personnel qualified for the specific task in accordance with the relevant documentation, in particular its warning notices and safety instructions.”
  • Contact service / dealer for assistance p. 13
    “NOTICE Property damage due to loose power connections Insufficient tightening torques or vibration can result in loose power connections. This can result in damage due to fire, device defects or malfunctions.”
