WARNING
Danger to life from electric shock due to improperly performed installation
The device uses voltage that is dangerous on contact as the electrical power supply. Potentially fatal
situations arise due to unsafe or incorrectly installation when reaching into the device.
► Ensure that the system is safely integrated into an emergency off safety circuit.
► Do not carry out any unauthorized modifications or changes to the device.
WARNING
Risk of cuts on moving, sharp-edged parts when reaching into the open high vacuum flange
With the high vacuum flange open, access to sharp-edged parts is possible. A manual rotation of the
rotor increases the danger situation. There is the risk of cuts, up to the separation of body parts (e.g.
fingertips). There is a risk of hair and loose clothing being drawn in. Objects falling in destroy the tur-
bopump during subsequent operation.
► Only remove the original protective covers immediately prior to connecting the high vacuum
flange.
► Do not reach into the high vacuum connection.
► Wear protective gloves during installation.
► Do not start the turbopump with open vacuum connections.
► Always carry out the mechanical installation before electrical connection.
► Prevent access to the high vacuum connection of the turbopump from the operator side (e.g.
open vacuum chamber).
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.
CAUTION
Risk of injury from bursting due to high pressure in the exhaust line
Faulty or insufficient exhaust lines cause hazardous situations, e.g. increase in exhaust pressure.
There is a risk of bursting. It is not possible to rule out the risk of injuries due to broken pieces flying
around, high escaping pressure and damage to the equipment.
► Lay the exhaust line without shut-off units.
► Observe the permissible pressures and pressure differentials of the product.
► Check the exhaust line regularly for correct function.
Risks during operation
WARNING
Danger of death from poisoning due to toxic gases being expelled without an exhaust line
Exhaust gases and vapors are released from the turbo pumping station unhindered during normal us-
age. In the case of processes with toxic media, there is a risk of injury and danger of death due to
poisoning.
► Note the corresponding regulations for handling toxic substances.
► Toxic process gases should be safely conveyed away via an exhaust line.
