WARNING
Strong magnetic field:
“ Persons wearing a pacemaker must keep outside the area of in-
fluence of the magnetic field ” !
Danger to life
Disregard of this safety instruction will always lead to accidents
with potentially fatal injuries or serious damage.
DANGER
Danger of damage to the pump or system
Disregard of this safety instruction will always lead to accidents
with potentially fatal injuries or serious damage.
WARNING
Danger of personal injury
Disregard of this safety instruction will always lead to accidents
with potentially fatal injuries or serious damage.
CAUTION
Disregard of this safety instruction may lead to accidents with minor
injuries or damage to property.
Use in explosive atmosphere
Use of the magnetic coupling on ATEX
category 3 Gi/o certified pump
It is recommended to use a progressive start-up for the vacuum pump
using a frequency inverter.
The temperature class of the coupling under normal operating condi-
tions corresponds to the internal and external temperature classes of
the vacuum pump.
CAUTION
In case of slippage, the coupling will heat up and thus exceed the
temperature class.
The slippage of the coupling can be monitored by the current
consumption of the motor : should it drop by more than 20% in re-
lation to the minimum current consumption of the motor under nor-
mal operating conditions, the pump must be stopped and removed
from the power supply.
Use of the magnetic coupling on ATEX
category 2 Gi/o certified pump
It is recommended to use a progressive start-up for the vacuum pump
using a frequency inverter.
CAUTION
For certified category 2G i/o pumps, the temperature class
must be watched by measuring the surface temperature of the cera-
mic bell using a PT100 temperature sensor installed on the pump.
WARNING
Minimum obligatory monitoring of the coupling for pumps with
certification
II 2G (i/o) IIB T3 (i/o)
Temperature of the magnetic coupling bell with the temperature
sensor TSA+/0106
The vacuum pump must immediately be stopped when one of the mo-
nitoring instruments exceeds the value defined in the “COBRA ATEX
Catalogue”.
It is the customer’s responsibility to operate his vacuum pump in accor-
dance with all security measures linked to the protection against explo-
sions.
DANGER
Any servicing on the pump must only be carried out by specially
trained servicing staff under strict adherence to current and valid
safety regulations. In case of possible risk from dangerous substan-
ces of any kind, the end user of the pump must duly inform and
instruct maintenance staff before any work is carried out.
Before any maintenance work is carried out, any risk to the health
of maintenance staff that could come from drawn substances or
any other substance both within or outside the pump, must be ex-
cluded.
Installation and
commissioning
Installation Prerequisites
●
Make sure that the integration of the vacuum pump complies with
the safety requirements of the Machine Directive 2006/42/EC
(concerning the responsibility of the manufacturer of the machine
or installation into which the vacuum pump is to be incorporated;
please also refer to the note in the EC-Declaration of Conformity).
Fitting
●
Make sure that the “Installation Prerequisites ” are followed.
●
Set up or mount the vacuum pump at its location
