3.3 24BSetup
The vacuum system SIMPLEX VO consists of a single-stage claw vacuum pump type MV with
integrated frequency converter for the drive. The vacuum pump is mounted on a vacuum ves-
sel.
The intake-side air filter and the strainer installed in the suction flange prevent the ingression
of dirt particles in the vacuum pump.
A pressure transmitter for pressure control is installed at the vacuum tank. The pressure in
the vacuum tank can be read using a vacuum meter.
Inlet and delivery side of vacuum system are completely piped. The motor is wired to a motor
protection switch.
The vacuum system is also available as a movable version with four rollers and a sliding brack-
et.

3.4 25BFunction principle
3.4.1 50BVacuum system VO
The single-stage claw vacuum pump evacuates a vacuum tank (VST, fig. 1), which serves as a
vacuum reservoir. The compressed gas of the vacuum pump is ejected against the atmos-
phere.
An air filter is installed between the vacuum pump and the vacuum vessel. The delivered gas
passes from the vacuum vessel to the air filter through to the vacuum pump. The air filter is
used to separate dust and other solid foreign substances from the extraction medium.
After switching on the main switch, the vacuum pump switches on. Via the pressure transmit-
ter installed in the vacuum vessel, the rotation speed of the motor is controlled by the fre-
quency converter depending on the pressure. If no vacuum is needed for some period (ad-
justable), the vacuum pump will switch itself off. When the set target pressure is exceeded,
the vacuum pump will switch on again automatically.
3.4.2 51BClaw-type vacuum pump MV
Fig. 3: Operating principle of the claw vacuum pump MV
The claw vacuum pump MV operates according to the claw principle.
3.5 26BIntended use
The vacuum system was designed for conveying air and other dry, non-aggressive, non-toxic
and non-explosive gases.
Conveying any other media leads to increased thermal and/or mechanical stress of the vacu-
um system and is only permitted in coordination with Busch.
The vacuum system is designed for operation in a non-hazardous area. The vacuum system
can be operated continuously at final pressure and is suitable for continuous operation at up
to 40 mbar. The permitted ambiance conditions can be found in the technical data (chap. 15).
The vacuum system is designed for indoor use; for outdoor installation, contact Busch to
make special arrangements if necessary.

5Storage
ATTENTION!
Danger of damage to the vacuum pump drive!
Long storage periods may cause capacitors in the drive to be weakened by electro-chemical
condensation. In the most detrimental case, this may cause short-circuit and thereby destruc-
tion of the drive.
•The vacuum pump should therefore be connected to the power supply for 30 minutes eve-
ry 18 months.
Proceed as follows for storage:
•Close all openings with the protective caps included in the scope of delivery (penetration of
dirt and water is prevented)
If storage for more than 3 months is intended:
•Secure loose cables
•Drain all process and operating media
•Clean and dry the vacuum system (Prior to storing make absolutely sure that all parts are
clean, drained and dry)
•Where necessary use oil for conservation
•Wrap the vacuum system in corrosion-inhibiting film.
•Store the vacuum system in a protected, dry and dust-free room at a temperature between
0 and 40 °C.

6.2 28BConnection lines/pipes
ATTENTION!
Danger of damage to the vacuum system from foreign bodies in the pipes.
•Remove all foreign matter (welding beads, filings, etc.) from the pipelines! This may be
done by flushing or blowing through pipelines.
The client must ensure that the pipework at the inlet is clean.
ATTENTION!
Vacuum system can be damaged by tensile or compressive stresses on pipeline connec-
tions!
•If stresses could occur, use compensators to connect pipelines.
ATTENTION!
Condensate damages vacuum pumps!
•Lay the piping on the intake and pressure sides at an angle to prevent accumulated con-
densation from entering the vacuum pump.
The line cross-section of the connection lines must have at least the same cross-section as the
connections of the vacuum system across the entire length.
In case of very long connection lines, it is recommended to use lines with larger cross-sections
to avoid loss of efficiency. Please contact your contact person from Busch.

6.3 29BElectrical connection
DANGER
Danger from electric shock!
Electric shock will cause death or serious injury.
•All live lines must be powered down before the electrical installation!
•Before any electrical work, ensure that the vacuum pump is disconnected from the power
supply and secured against accidental activation. Wait for another 60 seconds after the
LED displays switch off.
•Electrical installation work must only be performed by trained specialists.
ATTENTION!
Incorrect rotation of drive motors can seriously damage the vacuum system!
Switch vacuum pumps briefly on and off again to check the rotational direction of the motor.
The rotational direction is marked by a direction of rotation arrow on the motor.
If the direction is wrong, reverse two connection phase poles.
ATTENTION!
Over voltage damages the vacuum system.
During a high-voltage test, the frequency inverter must be disconnected due to danger of de-
stroying the power semi-conductors. The frequency inverter has already been subjected to a
high-voltage test with special test process in the final inspection.
6.3.1 54BConnection of the power supply
CAUTION
Danger due to accidental starting of the vacuum pump!
The vacuum pump starts up when the main switch is actuated.
Make sure that starting the vacuum pump does not lead to a dangerous situation.
ATTENTION!
Danger of damage to the vacuum system.
Wrong connection.
•Wire the vacuum system according to the wiring diagram chap. 14.2.
Procedure:
•Ensure that the power supply for the vacuum system corresponds to the specifications in
the circuit diagram.
•Ensure that the EMC class of the vacuum pump meets the requirements of your mains grid;
if necessary, provide additional interference suppression measures (for EMC class of the
vacuum pump, see technical data (chap. 15).
•We recommend using 16 A fuses of type gG/gL (IEC 60269-1). Ensure that the trigger time
does not exceed 0.4 seconds.
If you want to use a fault-current circuit breaker:
•Use an all-current-sensitive fault-current circuit breaker (type B).
•The synchronous motor and the frequency inverter have very high efficiency. High reactive
power may be displayed on some mains grids, but this does not affect the very high effi-
ciency of the vacuum pump drive.
