6.2. Electrical connection
DANGER
Extreme danger from electrical shock
Only have the pump connected by an authorized
specialist.
Only have the pump connected when the power
supply is disconnected.
When connecting the device to a power source, the relevant
standards, directives, regulations, and technical standards
must be observed.
Connecting pump
1. Compare the supply data with the data on the motor plate. For
maximum operating current of the pump see pump’s type
plate.
The voltage must not vary by more than + 10% and – 10%
from that shown on the type plate.
2. Insert the mains cable plug into a properly installed shockproof
socket.
Ensure sufficient dimensioning of the connection cables.
6.3. Pneumatic connection
CAUTION
Personal injury or damages to property by ejected
protective
plugs
If the
protective plug at the pressure side of the
pump hasn’t been removed, it could be ejected be-
cause of the overpressure during operation.
Remove the protective plug during the installa-
tion.
Only connect components to the pump which are designed for
the pneumatic data of the pump (see Chapter 4, Technical
Data).
If the pump s used as a vacuum pump, safely discharge the
pump exhaust at the pump’s pneumatic outlet.

Connecting pump
A marking on the pump head shows the direction of flow.
Confusion between suction and pressure sides can lead to
breakage of connected components on the suction and pres-
sure sides.
1. Remove the protective plugs from the hose connection
threads.
2. Connect the suction line and pressure line (see Chapter 4,
Tab. 7 for mounting dimensions).
3. Lay the suction and pressure line at a downward angle to pre-
vent condensate from running into the pump.

Danger of burns from hot pump parts or hot medium
During or after operation of the pump, some pump
parts may be hot.
Allow the pump to cool after operation.
Take safety precautions against the contact of
hot parts/media.
WARNING
Injury of the eyes
During excessive approach to the inlet or outlet of
the pump, the eyes could be injured by the upcoming
vacuum or overpressure.
Don’t look into the pump’s inlet or outlet during
the operation.
Only operate the pumps under the operating parameters and
conditions described in Chapter 4. Technical Data.
Make sure the pumps are used properly (see Chapter 2.1).
Make sure the pumps are not used improperly (see Chapter
2.2).
Observe the safety precautions (see Chapter 3).
