  • Page 6: 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.
