Page 5: Safety
● Power supply: The turbopump power supply must apply to the requirements of dou- ble insulation between mains input voltage and operating voltage according to the reg- ulations of IEC 61010 and IEC 60950. Therefore Pfeiffer Vacuum recommends to use exclusively original-power packs and -accessories. Only in this case Pfeiffer Vacuum is able to guarantee the compliance of the European and North American guidelines. -
Page 6: Proper Use
Following installation into a plant and before commissioning, the operator must check the entire system for compliance with the valid EU directives and reassess it accord- ingly. ● The electronic drive unit TC 400 E74 operates designated Pfeiffer Vacuum turbo- pumps and their accessories. Improper use Improper use will cause all claims for liability and warranties to be forfeited. -

Ensure the gas mode is correctly set. Contact Pfeiffer Vacuum before using gases with a greater molecular mass (> 80). ● Gas mode "0" for gases with the molecular mass >39, e.g. argon. ● Gas mode "1" for gases with the molecular mass 39. - Page 18 The Pfeiffer Vacuum parameter set Adjust the parameter [P:708] to the desired value in %. Set value power con- sumption If adjusting the set value power consumption below 100 % the run-up time prolongs. To avoid error messages, the parameter [P:700] RUTimeSVal should be adjusted accord- ingly.

- Page 20 Pfeiffer Vacuum recommends the intermittend mode between 5 and 10 hPa. A pressure gauge and a dosing valve are required to set the switching thresholds.
- Page 21 The Pfeiffer Vacuum parameter set Adjust the switch off threshold backing pump via parameter [P:710] to the determined drive power for a fore-vacuum pressure of 5 hPa. Delayed switching on Switching on the turbopump and the backing pump at the same time can result in un- wanted gas flows.

The Pfeiffer Vacuum parameter set Direct venting Start and venting time are not configurable. Venting starts with a delay of 6 s after "pump- ing station off". When the function "pumping station" is switched on renewed, the venting valve closes automatically. In the event of a power failure, venting will occur if an an- chored type-specific rotation speed is underrun. -
