2.2 Guidelines used and CE certification

Our products are subject to
- various EC directives
- various harmonized standards
- various national standards.
Please consult the EU Declaration of Conformity for the
precise information and the guidelines and norms in effect.

2.3 General safety


Never work alone when installing or removing
the product.

The machine must always be switched off
before any work is performed on it (assembly,
dismantling, maintenance, installation). The
machine must be disconnected from the
electrical system and secured against being
switched on again. All rotating parts must be
at a standstill.

The operator should inform his/her superior
immediately should any defects or
irregularities occur.

It is of vital importance that the system is shut
down immediately by the operator if any
problems arise which may endanger safety of
personnel. Problems of this kind include:




Tools and other objects should be kept in a
place reserved for them so that they can be
found quickly.

Sufficient ventilation must be provided in
enclosed rooms.

When welding or working with electronic
devices, ensure that there is no danger of
explosion.

To prevent suffocation and poisoning caused
by venomous gases, make sure that enough
oxygen exists at the workplace.

Immediately after repair or maintenance work,
all safety and protection equipment must be
reinstalled and placed in function again.

All other rules and regulations and local
codes covering health and safety must be
observed. In accordance with product liability
law, we point out that we shall not be liable
for damages caused by the pump due to non-
observance of the instructions and guidelines
set forth in the operating instructions. The
same product liability are valid for
accessories.
These instructions must be strictly observed.
Non-observance can result in injury or serious damage
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
personnel must be of age.
Operating and maintenance personnel must also work
according to local accident prevention regulations.
It must be ensured that personnel have read and
understood the instructions in this operating and
Failure of the safety and/or
control devices
Damage to critical parts

cables and insulation.
maintenance handbook; if necessary this manual must be
ordered from the manufacturer 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 device, 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
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.
Beware of electromagnetic radiation!
Electromagnetic 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 device.
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
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.
