vi CAUTION: Remarks for using ground fault interrupter breakers in the ..... 2–17 main power supply: Adjustable frequency inverters with CE-filters (RFI- filter) and shielded (screened) motor cables have a higher leakage current toward Earth GND. Especially at the moment of switching ON this can cause an inadvertent trip of ground fault interrupters. Because of the rectifier on the input side of the inverter there is the possibility to stall the switch-off function through small amounts of D

xi L100 Inverter CAUTION: SUPPRESSION FOR NOISE INTERFERENCE FROM INVERTER The inverter uses many semiconductor switching elements such as transistors and IGBTs. Thus, a radio receiver or measuring instrument located near the inverter is susceptible to noise interference. To protect the instruments from erroneous operation due to noise interference, they should be used well away from the inverter. It is also effective to shield the whole inverter structure. The addition of an EMI filter on t

xii CAUTION: When the EEPROM error E08 occurs, be sure to confirm the setting values again. CAUTION: When using normally closed active state settings (C_11 to C_15) for exter- nally commanded Forward or Reverse terminals [FW] or [RV], the inverter may start automatically when the external system is powered OFF or disconnected from the inverter! So, do not use normally closed active state settings for Forward or Reverse terminals [FW] or [RV] unless your system design protects against uninten
