These instructions must be strictly observed.
Non-observance can result in injury or serious da-
mage to property.
2.4. Operating personal
All personnel who work on or with the product must be
qualified for such work; electrical work, for example may
only be carried out by a qualified electrician. The entire per-
sonnel must be of age.
Operating and maintenance personnel must also work ac-
cording to local accident prevention regulations. It must
be ensured that personnel have read and understood the
instructions in this operating and maintenance handbook;
if necessary this manual must be ordered from the manu-
facturer in the required language.
2.5. Electrical work
Our electrical products are operated with single-phase or
three-phase-current. The local regulations (e.g. VDE 0100)
must be adhered to. The "Electrical connection" data
sheet must be observed when connecting the product.
The technical specifications must be strictly adhered to.
If the machine has been switched off by a protective de-
vice, it must not be switched on again until the error has
been corrected.
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 penetrate into the terminal
compartment or motor and cause damage to the ter-
minals 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.
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.
18 | ENGLISH
at construction sites), the grounded connection must be
additionally equipped with a fault current protection de-
vice.
2.6. Operating procedure
When operating the product, always follow the locally ap-
plicable laws and regulations for work safety, accident pre-
vention and handling electrical machinery. To help to ensu-
re safe working practice, the responsibilities of employees
should be clearly set out by the owner. All personnel 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 devices must never be dismantled or
disabled. Equipment must be checked by an electrician
for proper functioning before start-up (see the "Electrical
Connection" data sheet).
Please remember that certain equipment requires a de-
coder device or relay to function properly. This decoder
can be obtained from the manufacturer or a specialist
electronics dealer. Personnel must be informed of the in-
stallations 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. 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.
Different materials and impeller shapes are required for
different pumped fluids. The more exact your specifica-
tions on your order, the more exactly we can modify our
product to meet your requirements. If the area of applica-
tion and/or the pumped fluid change, we will be happy to
offer supportive advice.
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.
