Beware of damp!
Moisture penetrating cables can damage them and
render them useless. Furthermore, water can pen-
etrate into the terminal compartment or motor and
cause damage to the terminals 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.
at construction sites), the grounded connection must
be additionally equipped with a fault current protection
device.
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
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 Connec-
tion" 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 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. 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 general composition change, this can also alter many
parameters 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 application 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.
•
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!
