  • Page 6: Product Description

    E2658-N2O Rev 12.03.2021 Product description E2658 is a series of flameproof gas detectors-transmitters intended for operation in safe zones and ATEX Zones 2 and 22. E2658 series devices are based on PluraSens® multifunctional platform and provide all its features. The instruments utilize gas sensors of various types with excellent repeatability, stability, and long lifetime.
  • Page 7: Operating Conditions

    E2658-N2O Rev 12.03.2021 Operating conditions The device should be used in a basic electromagnetic environment, where the latter is defined in EN 61326-1. Avoid strong mechanical shock and vibrations. Although E2658 series devices are suitable for use in the presence of flammable dust, special precautions should be taken when operating in a dusty environment.
  • Page 8 E2658-N2O Rev 12.03.2021 The device is fixed on the wall using two fixing holes located outside the sealed area of the device (see dimensional drawing). Unscrew four lid screws and detach the lid from the detector. Fix the detector on the wall and earth the enclosure using an earthing terminal on the side of the device.

  • Page 10: Sensor Probe Handling

    E2658-N2O Rev 12.03.2021 Sensor probe handling The sensor probes of all types are equipped with a hydrophobic microporous PTFE filter to protect the sensor from dust, dirt, and water drops. The filter should be replaced if it gets strongly contaminated. To replace the PTFE filter, unscrew the sensor head cap and remove the old filter.
  • Page 11: Electrical Connections

    E2658-N2O Rev 12.03.2021 Electrical connections Unscrew four lid screws and detach the lid from the device. Use the M25 cable gland to let in the cables of the power supply and of the external devices. Without turning on the power, plug the power cable, and connect the analog/relay outputs and/or digital interface terminals to the necessary devices according to the relevant connection diagram.
  • Page 12 E2658-N2O Rev 12.03.2021 The screwless quick connect spring terminals on the E2658 series devices are suitable for a wide range of wires with cross-section 0,5...1,5 mm . We recommend to strip the wire end by 8...9 mm and use the wire end sleeves. To connect the wire, insert the wire end into the terminal hole.
