material; danger of damage to equipment and buildings.
ƒ Safety-oriented operation – The safety directions
contained in the manual, existing national regulations for
the prevention of accidents as well as internal guidelines
and safety-regulations for the operator and user must be
observed at all times.
ƒ General safety directions for the operator/user –
If hot or cold equipment parts pose a danger then they
must be protected by the operator/user against contact
with people. Protective covers for moving parts (e.g.
couplings) must not be removed when the equipment
is running. Leaks (e.g. at the shaft seal) of hazardous
pumping media (e.g. explosive, toxic, hot liquids) must be
disposed of in such a way that any danger to personnel
and the environment is removed. All government and lo-
cal regulations must be observed at all times. Any danger
to persons from electrical energy must be eliminated by
using good installation practices and working to local
regulations (e.g. VDE in Germany).
ƒ Safety directions for maintenance, inspection
and assembly work – It is the user's responsibility to
make sure that all maintenance, inspection and assembly
work is performed exclusively by authorized and qualified
experts sufficiently informed through careful study of the
operating instructions. The accident prevention regula-
tions must be observed. All work on the equipment must
be done when it is not operational and ideally electrically
isolated. Ensure all power sources and accessories (e.g.
float switch) are disconnected when working on the
system. Follow all appropriate electrical codes. There are
no user-serviceable parts inside the motor or the con-
troller. The sequence for shutting the equipment down is
described in the manual and must be strictly observed.
Pumps or pump units handling hazardous liquids must
be decontaminated. Immediately upon completion of
the work, all safety and protective equipment must be
restored and activated. Before restarting the equipment,
all points contained in chapter "Initial start-up" must be
observed.
ƒ Authorized changes and manufacturing of spare
parts – Any conversion of or changes to the equipment
may only be undertaken after consulting the manufac-
turer. Original spare parts and accessories authorized by
the manufacturer guarantee operational safety. Using
non-authorized parts may void any liability on part of the
manufacturer. There are no user-serviceable parts inside
the motor or the controller.
Safety Instructions
ƒ Unauthorized operation – The operational safety of
the equipment delivered is only guaranteed if the equip-
ment is used in accordance with the directions contained
in this manual. Limits stated in the data sheets may not
be exceeded under any circumstances.
