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

l

Make sure that the regulations of the Electromagnetic Compatibil-
ity Directive 2014/30/EU as well as standard EN norms, safety di-
rectives 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)

l

Make sure that the mains power supply corresponds to the data on
the nameplate of the motor

l

Make sure that an overload cut-out according to EN 60204-1 is
provided for the motor

l

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

l

Make sure that the “Necessary installation instructions” are fol-
lowed

l

Electrical connection

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 preven-
tion

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 motor!

Check the connection of the motor inside the terminal box
according to the circuit diagram.

Motor of screw pump DS 0080-2000 G is connected at factory.

Three phase motor connection:

Star connection (High voltage)

Delta connection (Low voltage)

Connection of supply cable to control box

l

Pass the cable through cable fitting of control box and put the first
phase in the box, in front of the still connected cable

l

Repeat the procedure for the two other terminals and the ground
terminal too
