WARNING
Risk of injury!
Danger of injury caused by falling motor/pump after loosening the fastening screws.
• Comply with national regulations for accident prevention and also with the operator's internal work, com-
pany, and safety regulations. If necessary, wear protective clothing and equipment!
DANGER
Danger of death!
The permanent magnet rotor inside the pump can be a danger to life for people with medical
implants during dismantling.
• Removal of rotor from the motor housing is permissible only for authorized and qualified personnel!
• If the unit consisting of impeller, bearing plate 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!
• Risk of crushing! When removing the rotor from the motor, it can be pulled back into its original position
by the strong magnetic field!
• If the rotor is outside the motor, magnetic objects may be attracted very suddenly. This may cause bodily
injury and property damage!
• Electronic devices can be impaired or damaged by the strong magnetic field of the rotor!
When assembled, the rotor's magnetic field is guided in the motor's iron core. However, there is no magnetic
field outside the motor that is harmful to health or affects the motor.
DANGER
Risk of fatal injury from electric shock!
Even without the module (without electrical connection), there may be dangerous contact
voltage at the motor contacts.
It is not permissible to dismantle the module!
15.2.1 Dismantling/installation of the motor
Take into account the "Shutdown" section before dismantling/installing the motor!
DANGER
