Electrical connection
The operator is required to know where the machine is supplied with current and how to cut off the
supply.
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.
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 addi-
tionally equipped with a fault current protection device.
The electrical products conform to motor protection class IP 68 in accor-
dance with the valid norms.
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 prac-
tice, 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. Cer-
tain materials can cause very sharp edges on these parts.
Safety and control
devices
Our products are equipped with various safety and control devices. These include, for example suc-
tion strainers, thermo sensors, sealed room monitor etc. These devices must never be dismantled
or disabled.
Equipment such as thermo sensors, float switches, etc. must be checked by an electrician for
proper functioning before start-up (see the “Electrical Connection” data sheet). Please remember
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. Never immerse cable ends in the pumped fluid or other
liquids. Any unused wires must be disconnected.
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.
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 mainte-
nance or repair work.
