5.5.6 Frequency inverter for vacuum pumps with 3-phase motor
Rotary vane pumps with variable rotation speed can be operated within a mains frequency range of 35
to 60 Hz. Start-up is ramped (maximum run-up time: 30 s). Shutdown can take place immediately.
5.5.7 Connecting the PTC thermistor tripping unit
Tripping units store the shut-down
Pfeiffer Vacuum recommends connecting motors with PTC in the stator winding to a PTC
resistor tripping device for protection against overload.
