WARNING

Electrical danger!

The terminal box must be free

from

 foreign bodies,

 dirt,

 humidity.

Terminal box cover and cable

entries must be tightly closed so

as to make them dustproof and

waterproof.

Check for tightness at regular

intervals.

For motor overload protection:

 Use motor circuit breakers.

 Set the motor circuit breakers to the

nominal current specified on the rating

plate.

For supply by converter:

 High-frequency current and voltage

harmonics in the motor supply cables can

lead to emitted electromagnetic

interference.

 Use shielded supply cables,

whereby the shield must be installed on

both sides.

 Limit speed:

see Chapter 4.2, "Electrical data", Pg. 16.

CAUTION

If the unit is run dry, the

mechanical seal will be

destroyed in a matter of seconds!

DO NOT switch on as long as the

unit is not filled with operating

liquid!

7.3 Connecting pipes/hoses (vacuum

pump/compressor)

Fig. 7: Pipe/hose connection of vacuum

pump/compressor

1 Operating-liquid port G ¼"

2 Discharge connection

3 Inlet connection

4 Connection for cavitation protection G ¼"

5 Drain opening G ¼"

To prevent foreign bodies from entering the

unit, all connections are sealed off when

delivered.

Do not remove the sealing plugs until

immediately before connecting the

pipes/hoses.

For the arrangement of the pipe/hose

connection, see Fig. 7, Pg. 25.

The pumped gases/vapors are sucked in via

the inlet connection

(see Chapter 7.3.1,

Pg. 26) and discharged via the discharge

connection (see Chapter 7.3.2, Pg. 26).

For operation the unit must be continuously

supplied with operating liquid.

This is fed in via the operating-liquid port

(see

Chapter 7.3.3, Pg. 26) and discharged

together with the pumped gases/vapors

through the discharge connection

.
