Risks in the event of malfunctions
WARNING
Danger to life from electric shock in the event of a fault
In the event of a fault, devices connected to the mains may be live. There is a danger to life from
electric shock when making contact with live components.
► Always keep the mains connection freely accessible so you can disconnect it at any time.
WARNING
Danger to life from the turbopump breaking away in the event of a fault
Sudden jamming of the rotor generates high destructive torques in accordance with ISO 27892. If the
turbopump is
not
properly secured, it can shear off. The energy that this would release could throw
the entire turbopump or shattered pieces from its interior through the surrounding space. Potentially
dangerous gases can escape. There is a risk of very serious injuries, including death, and extensive
property damage.
► Follow the installation instructions for this turbopump.
► Observe the requirements regarding stability and design of the counter flange.
► Use only original accessories or fixing material approved by Pfeiffer Vacuum for the installation.
WARNING
Risk of injury caused by the turbopump breaking away with the vibration compensator in the
event of a malfunction
Sudden jamming of the rotor generates high destructive torques in accordance with ISO 27892.
When using a vibration compensator, this will probably lead to the turbopump being sheared off in
use. The energy that this would release could throw the entire turbopump or shattered pieces from its
interior through the surrounding space. Potentially dangerous gases can escape. There is a risk of
very serious injuries, including death, and extensive property damage.
► Take suitable safety precautions on-site for the compensation of the occurring torques.
► Before installing a vibration compensator, you must first of all contact Pfeiffer Vacuum.
