Using non-nuclear qualified products in applications that require nuclear-qualified hardware or products may cause inaccurate readings. For information on Rosemount nuclear-qualified products, contact a Emerson Sales to follow these installation guidelines could result in death or serious injury.

7 Make sure only qualified personnel perform the could result in death or serious injury. Do not remove the connection head cover in explosive atmospheres when the circuit is live. Before connecting hart in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices. Verify the operating atmosphere of the Transmitter is consistent with the appropriate hazardous locations certifications. All connection head covers must be fully engaged to meet explosion-proof leaks could result in death or serious injury. Do not remove the thermowell while in operation. Install and tighten thermowells and sensors before applying shock could cause death or serious injury.
