Installation
Safely lead the exhaust gases away
Exhaust gases may, depending on the type of application, present a
health hazard and/or may be detrimental to the environment.
The exhaust gases from the vacuum pump must be safely led away and
subjected to post-treatment as required. In order to reduce the emission
of oil vapours we recommend the installation of an additional exhaust filter
(Leybold accessory, see Section 1.5). Depending on the type of applica-
tion or the kind of pumped media, the corresponding regulations and infor-
mation sheets must be observed.
When oil mist is to be removed from the exhaust flow we recommend the
use of the exhaust filter.
The maximum intake pressure must not exceed atmospheric pressure (1013
mbar).
Intake pressure for the gas ballast should be about 1013 mbar (absolute) and
sufficient quantities of gas must be available (about 1/10 of the pumping
speed).
3.4 Electrical Connections
Risk due to high voltages
Death or severe injury caused by an electric shock!
The electrical connections must only be made by a trained electrician as
specified, for example, by the regulations EN60204-1. Note the national
regulations of the country in which the equipment is being operated.
During all connection work, the mains power supply lines must be deener-
gised (lockout/tag out). In order to prevent the pump from running up un-
expectedly after a mains power failure, the pump must be integrated in
the control system in such a way that the pump can only be switched on
again manually. This applies equally to emergency cut-out arrangements.
Observe Safety Information 0.2.
3.4.1 Pump with Single-Phase AC Motor
With this design, the pump can be directly connected by means of the connect-
ing cable and plug to the corresponding AC mains, using a suitable fuse; refer
to the current value stated on the name plate of the motor.
The direction of rotation need not be checked as it is fixed. The motor is pro-
tected against overloading by a thermal overload switch. After this switch has
cut out the motor, the motor is automatically switched back on once it has
cooled down. That’s why the mains plug must be disconnected from the mains
before staring with any work on the pump.
