9 Maintenance
DANGER! Danger of death!
A fatal shock may occur when working on electrical equipment.
• The pump should be electrically isolated and secured against unauthorised switch-
on during any maintenance or repair work.
• Any damage to the connecting cable should always be rectified by a qualified
electrician only.
WARNING! Danger due to strong magnetic field!
Inside the machine there is always a strong magnetic field that can cause injury
and damage to property in the event of incorrect dismantling.
• It is only permitted to have the rotor removed from the motor housing by qualified
personnel!
• If the unit consisting of impeller, bearing shield and rotor is pulled out of the
motor, persons with medical aids, such as cardiac pacemakers, insulin pumps,
hearing aids, implants or similar are at risk. Death, severe injury and damage to
property may be the result. For such persons, a professional medical assessment is
always necessary.
In assembled condition, the rotor's magnetic field is guided in the motor's iron
core. There is therefore no harmful magnetic field outside the machine.
After successful maintenance and repair work, install and connect the pump
according to the "Installation and electrical connection" chapter. Switch on the
pump according to the "Commissioning" chapter.
