The following instructions for connection to the discharge only apply if

the drawn gas is discharged by the vacuum pump into a suitable envi-

ronment.

Make sure that the protection that was attached to prevent

penetration of particles during transport has been removed before

the vacuum pump is connected to the vacuum line

Make sure that the nominal diameter of the exhaust line is at least

equal to the diameter of the exhaust flange of the vacuum pump

to prevent a drop in the performance of the vacuum pump in the

case of a smaller cross-section

Make sure that the vacuum pump is connected with leakproof lines

CAUTION

When the discharge lines have been connected, make sure that the 

system does not leak. Leakages of dangerous substances must be

prevented!

Make sure that the discharge line is mounted in such a way that

condensate cannot penetrate into the pump (siphon trap, gradient)

Make sure that no shut-off devices are mounted in the discharge

line

Make sure that the discharge lines do not exercise any force on the

discharge flange. Mount bellows if necessary

The discharge flange has the following dimension:

DN 63 ISO-K

In the case of long discharge lines the line cross-section should be lar-

ger than the discharge flange to prevent a drop in the performance of

the vacuum pump. If you have any doubts, contact your Busch repre-

sentative.

Cooling water connection

The cooling water is generally connected with a hose. 
The cooling water outlet must be unpressurised.
Connection diameter: 3/8 NPT

Nitrogen connection

The nitrogen is connected with a pipe (leakproof against oxygen).
Connection diameter: 1/4 NPT

Electrical connection/ Checks

Make sure that the regulations of the Electromagnetic

Compatibility Directive 2014/30/EU as well as standard EN norms,

safety directives and especially local and national regulations are

observed (this is the responsibility of the manufacturer of the

system into which the vacuum pump is integrated according to the

Declaration of Conformity)

Make sure that the mains power supply corresponds to the data on

the nameplate of the motor

Make sure that an overload cut-out according to EN 60204-1 is

provided for the motor

Make sure that the drive of the vacuum pump is not disturbed by

any electric or electromagnetic interferences. If you have any

doubts, contact your Busch representative

Installation

Mounting

Make sure that the “Necessary installation instructions” are

followed

Fasten or install the pump at its final installation site

Electrical connection

Three phase motor connection

Star-star connection (Low voltage)

WARNING

Risk of electrocution, risk of damage.

Electrical installation must be performed by a suitably qualified 

electrician who knows and follows the following regulations:

-

IEC 364 or CENELEC HD 384 or DIN VDE 0100,

-

IEC Report 664 or DIN VDE 0110,

-

VBG 4 or corresponding national regulations on accident 

prevention

CAUTION

The circuit diagrams described below conform to the 

standard. Other circuit diagrams might be used. This 

depends on the particular order and the market.

Risk of damage to the motors!

Check the connection of the motors inside the terminal 

box according to the circuit diagram.

Motor of screw pump DS is connected at factory.

CAUTION

When connecting up the wires into the terminal box: please

make sure the tightening torque of 2 Nm is adhered to and

check with a calibrated torque wrench (Nuts M6).
