  • Page 10: Safety Precautions

    Safety precautions Safety precautions Installation The following safety precautions are to be observed when installing the frequency inverter: CAUTION Be sure to install the inverter on flame resistant material such as metal. Otherwise, there is a danger of fire. CAUTION Be shure not to place anything inflammable in the vicinity.

  • Page 11: Control And Operation

    Safety precautions CAUTION Remarks for using earth leakage circuit breakers in the mains supply: Frequency inverters with CE-filters (RFI-filter) and screened motor cables have a higher leakage current against earth. Especially in the moment of switching this can cause unintentional triggering of earth leakage circuit breakers. Because of the rectifier on the input side of the inverter there is the possibility to stall the switch-off function through amounts of DC current.

  • Page 12: Maintenance And Inspection

    Safety precautions CAUTION Check the following during and after the test run. Otherwise, there is a danger of machine breakage: Was the short cut bar between terminals +1 and + removed by mistake? Was the running direction of the motor correct? Was the inverter tripped during acceleration or deceleration? Were the indications of the rpm and the frequency meter correct? Were there any abnormal motor vibrations or noise?
  • Page 13 CAUTION PROTECTION AGAINST NOISE INTERFERENCE FROM THE INVERTER L2000 series inverters use many semiconductor switching elements such as transistors and IGBTs. For this reason, a radio set or measuring instrument located near the inverter is susceptible to noise interference. To protect the instruments from erreneous operation due to noise interference produced by the inverter, they should be installed well apart from the inverter.
