    Explosion-Protection Approvals Explosion-Protection Approvals The explosion-protection approvals are valid for use of the device in gas/vapour-air mixtures of combustible gases and vapours under atmospheric conditions. The explosion-protection approvals are not valid for use in oxygen-enriched atmospheres. Unauthorised opening of the enclosure invalidates the explosion-protection approval. —...

  • Page 6: Installing The Gas Transmitter

    Installing the Gas Transmitter Only trained service personnel (e.g. of Dräger) may install the gas transmitter under observation of relevant regulations. Installation and commissioning are described in the "Dräger PIR 3000 Installation Instructions" which are supplied with the gas transmitter. Mounting Location The protecting effect of the gas transmitter depends on the selection of the mounting location.

    Installing the Gas Transmitter The splash guard is held by a fixture provided with screw-thread, which is also used as calibration adapter. Make sure that the calibration adapter is correctly seated. To this end, manually tighten the calibration adapter to a point where the sealing line leaves a permanent mark on the splash guard.

  • Page 8: Electrical Installation

    Installing the Gas Transmitter Electrical Installation NOTICE If present: If the connector of the gas transmitter is not required, it must be removed prior to the electrical installation. To do so, cut the cables with a suitable tool directly in front of the connector, strip the insulation, and attach suitable ferrules. The entire wiring must correspond with applicable local regulations concerning the installation of electrical devices in potentially explosive atmospheres.
