Notes on ambient conditions
The specified permissible ambient temperatures apply to operation of the turbopump at
maximum permissible backing pressure or at maximum gas throughput, depending on the
cooling type. The turbopump is intrinsically safe thanks to redundant temperature monitor-
ing.
● The reduction in backing pressure or gas throughput permits operation of the turbo-
pump at higher ambient temperatures.
● If the maximum permissible operating temperature of the turbopump is exceeded, the
electronic drive unit first reduces the drive output and then switches it off where neces-
sary.
2.5 Proper use
► Use the turbopump only for generating vacuum.
► Use the turbopump only in combination with a suitable backing pump that can deliver up to the
required maximum fore-vacuum pressure.
► Use the turbopump only in closed indoor areas.
► Use the turbopump only for the evacuation of dry and inert gases.
2.6 Foreseeable improper use
Improper use of the product invalidates all warranty and liability claims. Any use that is counter to the
purpose of the product, whether intentional or unintentional, is regarded as misuse, in particular:
● Establishing the voltage supply without correct installation
● Installation with non-specified fastening material
● Pumping explosive media
● Pumping of corrosive media
● Pumping of condensing vapors
● Pumping of fluids
● Pumping of dust
● Operation with impermissible high gas throughput
● Operation with impermissible high fore-vacuum pressure
● Operation with excessively high irradiated heat output
● Operation in impermissible high magnetic fields
● Operation in an incorrect gas mode
● Venting with impermissible high venting rates
● Use for pressure generation
● Use in areas with ionizing radiation
● Operation in explosion-hazard areas
● Use in systems in which sporadic loads and vibrations or periodic forces act on the device
● The causing of hazardous operating conditions by a presetting on the electronic drive unit that is
contrary to the process
● Use of accessories or spare parts that are not listed in these instructions
