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 maintenance
handbook.
2.5. Electrical work
Our electrical products are operated with single-phase or three-phase-current. The local regulations 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.
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 control 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
Connection” data sheet). Please remember that certain equipment requires a decoder 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.
