■
Use in systems in which impact stress and vibrations or periodically occur-
ring forces affect pump, frequency converter and cables.
■
Operation on moving system or system components (locks, for example).
■
Operation at vibration absorbers and vacuum components (gate valves,
valves) which are not capable of sustaining the specified deceleration
torque should the pump rotor seize.
■
Stepping on pump, add-on parts, drive electronics, flanges and cables to
climb onto the system.
■
Fitting of add-on parts to the forevacuum flange which cause an inadmis-
sible high load.
■
Removing, covering or obstructing warning notices.
■
Standstill or storing of the pump without suitable seal ing-off and drying.
Storing in a humid atmosphere can cause corrosion.
■
Conversions, manipulations and maintenance work by personnel not
authorised by Leybold..
Any non-conforming utilisation of pump, frequency converter and accesso-
ries can result in severe injury or death and cause damage to components.
3.2 Operating environment
Permissible ambient tem-
perature
5 to 40 °C
Depending on the ambient temperature, the gas
throughput and the type of gas, forced air cooling or
water cooling may be necessary.
no dripping or spraying water, no explosive gas atmo-
spheres
Installation altitude
up to 4000 m
At altitudes over 2000 m heat dissipation by the ambi-
ent air is impaired.
3.3 Fitting accessories
Secondary devices are directly energised and activated via the accessory
connection X201 (M8 plug); by means of a Y-cable 2 accessories can be
connected at the same time.
In this case both devices will be switched parallelly (i.e. de-energised active /
in-active). The factory-set accessories’s interface features a plug-and-play
mode, and is instantly ready for operation with the connected device (ener-
gised with pump switched on).
