  • Page 16: Mounting

    In terms of material selection, due to special protective measures relating to possible contact surfaces between rotating and stationary components (impeller / inlet nozzle), ZIEHL-ABEGG ER..C plug fans satisfy the requirements of the EN 14986 standard. Steel plate (coated) is used as the material for the rotating component (impeller). If the impeller is purchased without a ZIEHL-ABEGG inlet nozzle, the system manufacturer is responsible for selecting the material for the stationary peripheral parts.

  • Page 17: Installation, Protection From External Influences

    The fan should be mounted on suitable vibration dampers. These are available as accessories from ZIEHL-ABEGG. Pipes and ductwork may only be connected via elastic connections (expansion joints), which are available as accessories. When purchasing expansion joints that are not supplied by ZIEHL-ABEGG, the system manufacturer must ensure that they comply with Directive 2014/34/EU or that they have corresponding type examination certificates.

    The motors have triplet PTC’s. More than two PTC’s may not be connected in series, as this can lead to undefined shut-downs. • PTC thermistor release unit, e.g. ZIEHL-ABEGG type U-EK230E with disconnection via a contactor. • A current dependent protection is not admissible and also not possible as secondary protection.

  • Page 27: During Start-Up Check The Following

    Check the system for resonances. If they lead to unacceptably high vibrations on the fan, the system may not be started up. If necessary, contact ZIEHL-ABEGG SE service and observe the table of resonant frequencies for ER..C fans in Chapter 6.3.
  • Page 28 Assembly instructions RH..C and ER..C Start-up In addition, perform the following tests before switching on an explosion-pro- tected fan: • Check the operating conditions / process parameters (see “Intended use”). Above all, it is essential to ensure that the maximum permitted values for speed, suction and ambient temperature (see rating plate) are not exceeded under any circumstances and at any time.
