Beware of electrical current!
Incorrectly performed electrical work can result in
fatal injury!This work may only be carried out by a
qualified electrician.
Beware of damp!
Moisture penetrating cables can damage them and
render them useless. Furthermore, water can pene-
trate into the motor and cause damage to the termi-
nals or the winding. Never immerse cable ends in the
pumped fluid or other liquids.
2.5.1. Electrical connection
When the machine is connected to the electrical control
panel, especially when electronic devices such as soft
startup control or frequency drives are used, the relay
manufacturer's specifications must be followed in order
to conform to EMC. Special separate shielding measures
e.g. special cables may be necessary for the power supply
and control cables. The connections may only be made
if the relays meet the harmonized EU standards. Mobile
radio equipment may cause malfunctions.
Beware of electromagnetic radiation! Electromag-
netic radiation can pose a fatal risk for people with
pacemakers. Put up appropriate signs and make sure
anyone affected is aware of the danger.
2.5.2. Ground connection
Our products (machine including protective devices and
operating position, auxiliary hoisting gear) must always be
grounded. If there is a possibility that people can come
into contact with the machine and the pumped liquid (e.g.
at construction sites), the grounded connection must be
additionally equipped with a fault current protection de-
vice. The electrical motors conform to motor protection
class IP 68 in accordance with the valid norms.
2.6. Operating procedure
When operating the product, always follow the locally
applicable laws and regulations for work safety, accident
prevention and handling electrical machinery. To help to
ensure safe working practice, the responsibilities of em-
ployees should be clearly set out by the owner. All per-
sonnel are responsible for ensuring that regulations are
observed. Certain parts such as the rotor and propeller
rotate during operation in order to pump the fluid. Certain
materials can cause very sharp edges on these parts.
Beware of rotating parts! The moving parts can
crush and sever limbs. Never reach into the pump
unit or the moving parts during operation. Switch off
the machine and let the moving parts come to a rest
before maintenance or repair work!
2.7. Safety and control devices
Our products are equipped with various safety and con-
trol devices. These include, for example suction strainers,
thermo sensors, sealed room monitor etc. These devices
must never be dismantled or disabled. Equipment such as
thermo sensors, float switches, etc. must be checked by
an electrician for proper functioning before start-up (see
the "Electrical Connection" data sheet).
24 | ENGLISH
Please remember that certain equipment requires a de-
coder device or relay to function properly, e.g. posistor
and PT100 sensor. This decoder can be obtained from the
manufacturer or a specialist electronics dealer. Personnel
must be informed of the installations used and how they
work.
Caution!
Never operate the machine if the safety and monitor-
ing devices have been removed or damage, or if they
do not work.
2.8. Operation in an explosive atmosphere
Products marked as explosion-proof are suitable for opera-
tion in an explosive atmosphere. The products must meet
certain guidelines for this type of use. Certain rules of con-
duct and guidelines must be adhered to by the operator as
well. Products that have been approved for operation in an
explosive atmosphere are marked as explosion-protected
"Ex" . In addition, an "Ex" symbol must be included on the
type plate! When used in an explosive atmosphere, the
additional chapter entitled "Explosion protection accord-
ing to the ...standard" must be observed!
2.9. Pumped fluids
Each pumped fluid differs in regard to composition, cor-
rosiveness, abrasiveness, TS content and many other
aspects. Generally, our products can be used for many
applications. For more precise details, see chapter 3, the
machine data sheet and the order confirmation. It should
be remembered that if the density, viscosity or the gener-
al composition change, this can also alter many parame-
ters of the product.
When switching the product into another pumped fluid,
observe the following points:
•
Products which have been operated in sewage or
waste water must be thoroughly cleaned with pure
water or drinking water before use.
•
Products which have pumped fluids which are haz-
ardous to health must always be decontaminated be-
fore changing to a new fluid. Also clarify whether the
product may be used in a different pumped fluid.
•
With products which have been operated with a lu-
bricant or cooling fluid (such as oil), this can escape
into the pumped fluid if the mechanical shaft seal is
defective.
Danger - explosive fluids!
It is absolutely prohibited to pump explosive liquids
(e.g. gasoline, kerosene, etc.). The products are not
designed for these liquids!
3. General description
3.1. Application
The agitators are suitable for use in mixing, i.e. homoge-
nizing and suspending liquids with low to medium viscosi-
ty. Depending on the pumped medium, the solids content
may be up to 6%.
