    ECHNICAL DATA User qualification Target group The DIQ/S 182 system was developed for online analysis. Some maintenance activities, e.g. changing the membrane caps in D.O. sensors, require the safe handling of chemicals. Thus, we assume that the maintenance personnel is familiar with the necessary precautions to take when dealing with chemicals as a result of their professional training and experience.
  • Page 19 WARNING A circuit (except for the power supply connections), that is connected to an DIQ/S 182 component, must not feed any voltages or currents that are not allowed. It has to be made sure that the circuit at any time meets all requirements of a Limited circuit or Limited Power as well as of SELV (Safety Extra Low Voltage).
