English SAFETY
2.3. Electrical work
ELECTRICAL hazard!
Incorrectly performed electrical work can
result in fatal injury! This work may only be
carried out by a qualied electrician.
BEWARE of moisture!
Moisture penetrating the cable will damage
both the pump and the cable. Never immerse
the cable end in uid and always protect it
from moisture. Unused wires must be insu-
lated!
Ourpumpsareoperatedwithalternatingor
three-phase current. The governing nation-
aldirectives,standardsandregulations(e.g.
VDE0100)aswellastherequirementsofthelocal
energy supply company must be observed.
The person operating the pump must know
where it is supplied with power and how to cut
off the supply. A motor protection switch must
beinstalledbythecustomerforthree-phaseAC
motors. It is advisable to install a residual-current
device(RCD).Ifthereisapossibilitythatpeople
can come into contact with the pump and the
uid(forexampleonconstructionsites),the
connection must be equipped with an additional
residual-currentdevice(RCD).
Thesectionentitled“Electricalconnection”must
be observed when connecting the product. The
technicalspecicationsmustbeobservedstrictly.
Ourpumpsmustalwaysbegrounded.
If the pump has been switched off by a protec-
tive device, it must not be switched on again
until the error has been corrected.
When the pump is connected to the electrical
controlpanel,particularlywhenelectronicdevices
such as soft start-up control or frequency con-
vertersareused,theswitchgearmanufacturer’s
specicationsmustbefollowedtocomplywith
theelectromagneticcompatibility(EMC)require-
ments. Special separate shielding measures (e.g.
shieldedcables,lters,etc.)maybenecessaryfor
the power supply and control cables.
Connections may only be made providing the
switchgears meet the harmonised EU standards.
Mobile radio equipment may cause malfunc-
tions in the system.
BEWARE of electromagnetic radiation!
Electromagnetic radiation can pose a fatal
risk for people with cardiac stimulators. Put
up appropriate signs and make sure anyone
affected is aware of the danger!
2.4. Safety and monitoring devices
The pumps are equipped with a thermal winding
monitor and leakage connection for the motor.
The pump is switched off if the motor gets too
hot during operation or if liquid gets into the
motor.
These devices must be connected by an electri-
cian and checked to ensure that they function
correctly before commissioning.
Personnel must be informed about the installed
systems and how they work.
CAUTION!
Never operate the pump if the monitoring
devices have been removed or damaged, or if
they do not work.
2.5. Safety rules during operation
Whenoperatingthepump,alwaysfollowthe
locally applicable laws and regulations for work
safety,accidentpreventionandhandlingelec-
trical machinery. To help ensure safe working
practice,theresponsibilitiesofemployeesshould
beclearlyspeciedbytheoperator.Allpersonnel
are responsible for ensuring that regulations are
observed.
Duetotheirdesign,centrifugalpumpshave
rotating parts that are easily accessible. Depend-
ingontheoperatingcondition,sharpedgescan
develop on these parts.
WARNING: Danger of crushing and amputation
of limbs!
Sharp edges can form on the rotating parts in
the hydraulics. These can result in crushing
and amputation of limbs.
• Never reach into the hydraulics when the
machine is in operation.
• Before performing maintenance or repairs,
switch off the pump, disconnect it from the
mains and secure it against being switched on
again without authorization.
• Always allow the rotating parts to come to a
standstill!
2.6. Fluids
Eachuiddiffersinrespectofcomposition,cor-
rosiveness,abrasiveness,drymattercontentand
inmanyotheraspects.Generally,ourpumpscan
be used for many applications. Please note that if
requirementschange(density,viscosityorgeneral
composition),thiscanalsoaffectmanyparame-
ters of the pump.
When using or replacing the pump in a different
uid,observethefollowingpoints:
• Theuidcanbecontaminatedbyoilfromthe
sealing chamber if the mechanical shaft seal is
defective.
Use with potable water is not permitted!
• Pumps that have been operated in dirty waste
water must be cleaned thoroughly before being
usedforotheruids.
• Pumps that have been operated in sewage water
containingfaecesand/oruidsthatarehazardous
to health must be decontaminated before being
usedwithotheruids.
