  • Page 7: Electrical Connection

    Electrical connection Installation notes - The choice of cable, the installation, the fusing and the electrical connection must conform to the requirements of VDE 0100 “Regulations on the Installation of Power Circuits with nominal voltages below 1000V”, or the appropriate local regulations. - The electrical connection must only be carried out by qualified personnel.
  • Page 8 configuration levels, internal adjustments). Safety devices independent of the controller, such as overpressure valves or temperature limiters/monitors, should always be provided and should be capable of adjustment only by specialist personnel. Please refer to the appropriate safety regulations in this connection. Since auto-tuning (self- optimization) cannot be expected to handle all possible control loops, there is a theoretical possibility of unstable parameter settings.
