Marking Note: the nameplate does not shows intrinsic safety parameters because external connections ARE NOT subjected to intrinsic safety. 2 - SAFETY INSTRUCTIONS This capacitive level switch is designed to be installed in potentially explosive atmosphere for the combustible dust presence. Make sure that the device marking is in compliance with the area classification; do not install the device in the explosive gases presence (0, 1 or 2 zone). Verify that the probe installation does not affect the degree of protection. Device improper use may cause damage to people, the product and connected equipments. Always observe the nameplate data for the power supply and the electrical connections. 3 - INSTALLATION AND COMMISSIONING The installation must be performed only by qualified and properly trained personnel in accordance with current regulations (Rif. EN 60079-14). The equipment must be used only after having correctly understood the instructions in this document, together with the 825B097_ user manual. The device must be installed so as to avoid the risk of shock to the housing and to the sensitive part. All the electrical connections must be realized with non-active conductors; be sure that, during wiring operations, the potentially explosive atmosphere is not present. Use only the threaded connection (wrench 50) to insert the probe into the process connection; do not use the housing to manually screw the sensor into the process connection. Properly tighten the cable glands and the cover, just before commissioning. When necessary, replace the cable entries with other similar devices, make sure that the marking is in suitable for the installation area (2D) and the minimum dustproof degree (IP6X). The housing is provided with a breathing valve: make sure that during the installation, the breathing function is not avoided. For the electrical connections and instrument settings, please refers to 825B097_ user manual.
