Operation

Faults of electronic devices due to electromagnetic fields
Electromagnetic fields are created during the operation of pumps with frequency con-
verter. Interference of electronic devices may be the result. The result may be a device
malfunction, which can result in damage to the health or even death, e.g. of persons with
implanted active or passive medical devices. Therefore, during operation the presence of
any persons e.g. with cardiac pacemakers in the vicinity of the unit/pump should be pro-
hibited. With magnetic or electronic data media, the loss of data is possible.
8.4

Shutdown

The pump must be shut down before conducting maintenance, repair or dismantling
work.
DANGER! Risk of fatal accident!
Deadly electric shock may occur when working on electrical equipment.
• Have work on the electrical part of the pump carried out only by a qualified electrician
as a basic principle.
• Before starting any maintenance and repair work, disconnect the pump from the power
supply, and make sure it cannot be switched back on by unauthorised persons.
• Work on the control module may only be started after 5 minutes have elapsed, due to
the dangerous residual contact voltage.
• Check to ensure that all connections (including potential-free contacts) are voltage-free.
• The pump may still be live even in voltage-free state. The drive rotor induces a danger-
ous contact voltage at the motor contacts.
Close the check valves in front of and behind the pump.
• If the control module/plug is damaged, the pump must not be put into operation.
WARNING! Risk of burns!
Touching the pump can cause burns!
Depending on the operating status of the pump or unit (fluid temperature), the entire
pump can become very hot.
Allow the system and pump to cool down to room temperature.

9 Maintenance

Before carrying out maintenance / cleaning and repair work, observe sections 8.3 "Oper-
ation", 8.4 "Shutdown" and 9.1 "Dismantling/installation".
The safety instructions in section 2.6 and chapter 7 must be complied with.
After completing maintenance and repair work, install and connect the pump according to
chapter 7 "Installation and electrical connection". Switch on the pump according to chap-
ter 8 "Commissioning".
