•
Failure of the safety and/or control devices
•
Damage to critical parts
•
Damage to electric installations, cables and
insulation.
•
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.
•
Only use fastening devices which are legally defined
as such and officially approved.
•
The fastening devices should be suitable for the
conditions of use (weather, hooking system, load,
etc). If these are separated from the machine after
use, they should be expressly marked as fastening
devices. Otherwise they should be carefully stored.
•
Mobile working equipment for lifting loads should
be used in a manner that ensures the stability of the
working apparatus during operation.
•
When using mobile working equipment for lifting
non guided loads, measures should be taken to avoid
tipping and sliding etc.
•
Measures should be taken that no person is ever
directly beneath a suspended load. Furthermore,
it is also prohibited to move suspended loads over
workplaces where people are present.
•
If mobile working equipment is used for lifting loads,
a second person should be present to coordinate the
procedure if needed (for example if the operator‘s
field of vision is blocked).
•
The load to be lifted must be transported in such a
manner that nobody can be injured in the case of a
power cut. Additionally, when working outdoors,
such procedures must be interrupted immediately if
weather conditions worsen.
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 pre-
vention regulations. It must be ensured that personnel
have read and understood the instructions in this operat-
ing and 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 alternating or
industrial high-voltage current. The local regulations (e.g.
VDE 0100) must be adhered to. The “Electrical connec-
tion” 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 de-
vice. 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 em-
ployees should be clearly set out by the owner. All per-
sonnel 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!
