Tab. 2 (part 2) ** Automatic voltage selection
The pumps of the vacuum pump systems are supplied by a
universal power supply with integrated overload protection.
They are protected against overheating by a temperature
sensor on the motor board and equipped with overcurrent
protection.
If one of these safety functions is triggered, the pump will be
shut down and must be manually reset, as follows:

Separate pump from the mains.

Remove the cause(s) of the fault before restarting.
