 WARNING
Danger due to rotating parts! Danger due to
vacuum
and gauge pressure! Danger due to
escaping fluid!
Test runs may also only be conducted with the
pump-motor unit completely mounted.
 DANGER
Electrical danger!
The electrical connection may be carried out by
trained and authorized electricians only!
 DANGER
Electrical danger!
Before beginning work on the unit or system, the
following measures must be carried out:
 Deenergize.
 Secure against being switched on again.
 Determine whether deenergized.
 Ground and short-circuit.
 Cover or block off adjacent energized parts.
Check operating speeds:
Observe the operating speed specified on the
rating plate. This may not be exceeded, as
otherwise the noise radiation, vibration behavior,
grease consumption duration and bearing
change interval worsen. To prevent damage as a
result of higher speeds, it may be necessary to
inquire with the Service Department as to the
maximum speed.
 WARNING
Danger of hearing damage due to noise
radiation!
For the noise emission of the pump-motor unit
measured by the manufacturer, see Chapter
3.1, "Mechanical data", Section "Noise level",
Pg. 8. However, the actual noise emission
during operation is highly dependent on the
installation and system conditions. Conduct a
noise measurement in the system during
operation after installing the pump-motor unit.
The following measures can be taken from
85 dB(A) and must be taken from 90 dB(A):
 Mark noise area with a warning sign.
 Wear hearing protection.
 With free entry and exit of gases, i.e. with
direct intake out of or direct feeding into the
atmosphere without piping, attach an
additional muffler.
6.2 Start-up and shut-down
Start-up
 Open shut-off device in intake/discharge pipe.
 Switch on power supply for drive motor.
Shut-down:
 Switch off power supply for drive motor.
 Close shut-off device in intake/discharge pipe.
