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.
2.3 Safety precautions
Duty to provide information on potential dangers
The product holder or user is obliged to make all operating personnel aware of dan-
gers posed by this product.
Every person who is involved in the installation, operation or maintenance of the
product must read, understand, and adhere to the safety-related parts of this docu-
ment.
Infringement of conformity due to modifications to the product

General safety precautions when handling the product
► Observe all applicable safety and accident prevention regulations.
► Check that all safety measures are observed at regular intervals.
► Do not expose body parts to the vacuum.
► Always ensure a secure connection to the earthed conductor (PE).
► Never disconnect plug connections during operation.
► Observe the above shutdown procedures.
► Before working on the high vacuum connection, wait until the rotor has stopped completely (rota-
tion speed f = 0).
► Never put the device into operation with the high vacuum connection open.
► Keep lines and cables away from hot surfaces (> 70°C).
► Never fill or operate the unit with cleaning agents or cleaning agent residues.
► Do not carry out your own conversions or modifications on the unit.
► Observe the unit protection class prior to installation or operation in other environments.
