The ends of the 3 phases are connected in the star point. The terminal voltage is √3 times the phase 
voltage, the mains current is equal to the phase current. The star circuit is marked with the Y symbol.

5.6.2 Checking the direction of rotation

Fig. 8:

Check of direction of rotation

Procedure

When switching on for the first time, check the roots pump direction of rotation.

1. Switch the vacuum pump on briefly (2 to 3 seconds)

– The motor and coupling must rotate clockwise (see directional arrow on housing cover).

2. If the direction of rotation is incorrect, exchange the 2 phases on the connection cable.

5.6.3 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.
