0.1 Mechanical Hazards
1
Loss of stability during transport. Uncontrolled movement due to incor-
rect attachment / lifting / carrying / rolling or movement of the vacuum
pump.
Only use the attachment points and conveying means described in this
manual for vertical and horizontal conveying.
2
Ejection of parts through bursting of vacuum system as a result of
excessive pressure caused by clogged or constricted exhaust.
Pressure build-up in the vacuum system or exhaust pipes.
Do not start up or operate the vacuum system with the outlet closed
or throttled.
3
Ejection of parts through bursting of vacuum system due to excessive
pressure, caused by faulty function at the gas inlet into the vacuum
system.
Pressure build-up in the vacuum system or inlet lines.
Check correct connection of inlet and outlet flanges before commis-
sioning. The inlet pressure at the suction port of the vacuum system
must not exceed atmospheric pressure. If seal gas or gas ballast from
pressure vessels is used, secure the supply in such a way that no
overpressure can occur in the vacuum system in the event of a fault or
power interruption
4
Ejection of parts through bursting of vacuum system as a result of
excessive pressure caused by the pump running backwards after it
has been switched off under vacuum.
Danger of overpressure in the inlet lines and recipients as well as
uncontrolled backward running of rotors.
In the event of a fault or during service, separate the vacuum pumps
from the vacuum vessel and connecting lines before the inlet by means
of suitable valves.
5
Risk of cutting and cutting off by contact with moving parts such as
couplings, shafts and rotors.
Risk of cutting and crushing when reaching into open flanges or cov-
ers.
Do not operate the vacuum pump with open flanges or covers. When
installing, first mechanically connect the inlets and outlets, close the
covers of rotating parts and then make the electrical connections.
Disconnect the vacuum pump from the power supply before servicing.
Only use trained service personnel.
