Operating instructions G3G250-GN39-01
Translation of the original operating instructions
4.2.3 Residual current operated device
Only pulse-current sensitive and/or universal RCD protective
devices (Type A or B) are permitted. Like frequency inverters,
RCD protective devices cannot provide personal safety while
operating the device. When switching on the power supply of
the device, pulsed charge currents from the capacitors in the
integrated EMC filter can lead to the RCD protective devices
triggering without delay. We recommend residual current
devices with a trigger threshold of 300 mA and delayed
triggering (super-resistant, characteristic K).
4.2.4 Locked-rotor protection
Due to the locked-rotor protection, the start-up current (LRA) is
equal to or less than the nominal current (FLA).
