0.6 Risk of damaging the pump
1 Never touch the rotor. Touching the rotor may cause injury and
damage the rotor bearing.
2 Foreign objects which enter the pump through the intake would cause
serious damage to the rotor. That’s why we recommend installing an
inlet screen. Damages caused during operation without the inlet screen
are excluded from warranty.
3 The contact surfaces of pump housing, vacuum system and centering
ring must be free of grease and dry so as to ensure sufficient stability
in case the rotor seizes.
4 Connect a purge gas or venting valve to the correct flange. Confusing
the forevacuum and purge gas flange can cause shock venting of the
pump.
5 The interface connectors have UNC 4-40 threads. Do not use connec-
tors with M3 treads.
6 Disconnect and connect the cable connections only while the pump is
turning no longer (green status LED off) and with the mains power
switched off (yellow power LED off). Other wise there is the risk of dam-
aging the frequency converter.
7 Do not stop the MAG with the mains. Switching off the mains while the
pump is running will wear out the touch down bear ings.
8 Exposure of the pump to accelerating forces must be avoided or
reduced to such an extent that the rotor unit will not be excited by
vibrations. In the case of critical applications you must consult our
Applications Dept. first.
9 Connect the pump in an EMC compliant manner so as to avoid line
related interference.
Pressures given in bar or mbar are absolute values. If exceptionally a gauge
pressure is meant, a “g” is added (bar(g)).
