BUSCH COBRA BC 0200 F, Installation And Maintenance Instructions Manual

Page: 12 / 24

l The inlet flange has the following dimension:
–
DN 50 ISO KF
In the case of long intake lines the line cross-section should be larger
than the intake flange to prevent a drop in the performance of the va-
cuum pump. If you have any doubts, contact your Busch representa-
tive.
Discharge connection
CAUTION
Do not put hands into the outlet aperture.
Risk of body damage !
The following instructions for connection to the discharge only apply if
the sucked gas is discharged by the vacuum pump into a suitable envi-
ronment.
l 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
l 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
l 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!
l Make sure that the discharge line is mounted in such a way that
condensate cannot penetrate into the pump (siphon trap, gradient)
l Make sure that no shut-off devices are mounted in the discharge
line
l Make sure that the discharge lines do not exercise any force on the
discharge flange. Mount bellows if necessary
l The discharge flange has the following dimension:
–
DN 40 ISO KF
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
l 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)
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

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
prevention
CAUTION

Other circuit diagrams might be used. This depends on the particu-
lar order and the market.
Risk of damage to the motor!
Check the connection of the motor inside the terminal box accor-
ding to the circuit diagram.
Motor of screw pump COBRA BC 0200 F is connected at factory.
l Connect supply cable on the female connection (EC) of the
vacuum pump
