Mechanical Data; Figure 2 Performance Characteristics - Edwards XDS46i Instruction Manual

Sound pressure, measured at ultimate vacuum
1 metre from the end of the pump to ISO 3744
and ISO 4871
Vibration: measured at the inlet port (ISO 3744) Class 1C...< 4.5 mm s-
The position of the gas ballast control defines the performance characteristics of the
pump.

Note:
The pump is not suitable for prolonged operation at inlet pressures above 40 mbar.
Under such conditions, the inverter may reduce the motor speed.
