Lorentz PSk2-7 Manuel D'installation Et De Fonctionnement page 16

14 Operating Conditions
The manual contains basic instructions which must be
observed during installation, operation and maintenance.
Before installation and start-up, the manual should be
carefully read by the person in charge of the installation. The
manual should also be read by all other technical personnel/
operators and should be available at the installation site at
all times.
ƒ Personnel qualifications and training – All pesonnel
for the operation, maintenance, inspection and installtion
must be fully qualified to perform that type of job.
Responsibility, competence and the supervision of such
personnel must be strictly regulated by the operator.
Should the available personnel be lacking the necessary
qualification, they must be trained and instructed accord-
ingly. If necessary, the operator may request the manu-
facturer/supplier to provide such training. Furthermore
the operator/user must make sure that the personnel fully
understand the contents of the manual.
ƒ Dangers of ignoring the safety symbols – Ignoring
the safety directions and symbols may pose a danger
to humans as well as to the environment and the
equipment itself. Non-observance may void the warranty.
Non-observance of safety directions and symbols may
for example entail the following: Failure of important
functions of the equipment/plant; failure of prescribed
methods for maintenance and repair; danger to persons
through electrical, mechanical and chemical effects; dan-
ger to the environment because of leakage of hazardous
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 Unauthorized changes and manufacturing of
spare parts – Any conversion of or changes to the
equipment may only be undertaken after consulting
the manufacturer. 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-servicea-
ble parts inside the motor or the controller.
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.
