SPECIAL SAFETY INSTRUCTION This document lists specific requirements which have to be fulfilled to secure a safe installation and use of Rosemount TankRadar REX in hazardous area. Omission may jeopardize safety, and Rosemount Tank Radar AB will not take any responsibility if requirements as listed below are not fulfilled. 1-1

Chapter 1 General Requirements 1. General Requirements 1.1 Safety Instructions The REX 3900 gauge must be installed by suitably trained personnel according to the accompanied instructions and in accordance with the applicable code of practice. An X suffix on the approval number (e.g. Baseefa 03ATEX0071X) indicates that special conditions for safe use apply. Make sure that the connected power supply is in accordance with the marking on the REX 3900 gauge. Select external fuse rating with respect to area temperature classification (T1-T6) and maximum expected ambient temperature to prevent overheating of the W11 wiring (0.5 mm 2 ), see Figure 3-1. Example: maximum allowed (fault) current in a T4 installation with 70 C ambient is 7.5 A according to the lead seal compartment certificate PTB 97 ATEX 1047 U. 1-2

Chapter 1 General Requirements 1.2 Flameproof/Explosionproof Enclosures Flameproof/Explosionproof enclosures of Radar Tank Gauges (RTG) may not be opened while energized. Rosemount Tank Radar AB will not take any responsibility for local regulations defining conditions when flame proof enclosures are allowed to be opened while energized.

Chapter 1 General Requirements 1-4

Chapter 2 Explosion Protection Techniques 2. Explosion Protection Techniques TankRadar REX equipment is often used in areas where flammable materials are handled and where an explosive gas atmosphere may be present, so called hazardous areas. To protect the environment and the personnel, precautions must be taken to ensure that this atmosphere cannot be ignited. Consequently, equipment within hazardous areas must be explosion protected. A number of different explosion protection techniques have been developed over the years. Intrinsic Safety, Flameproof/Explosionproof enclosures and Increased Safety are different techniques. The basic principles of explosion protection are: Flammable materials are grouped according to the energy needed to ignite them. Equipment located in hazardous areas are classified according to the maximum surface temperature that it can produce and this must be safe with the flammable gases that may be present. Hazardous areas are classified according to the probability that an explosive atmosphere is present, and this dictates whether or not a particular explosion protection technique may be used. 2.1 Intrinsic Safety Intrinsic safety, IS, is based on the principle of restricting electrical energy available in hazardous-area circuits such that any sparks or hot surfaces, that may occur as a result of electrical faults in components, are unable to cause ignition. Intrinsic safety is the only technique accepted for Zone 0 hazardous areas. For example, temperature measurement with the DAU is intrinsically safe. Note! Special care and skills is necessary for troubleshooting in Intrinsically Safe circuits. Instruments for troubleshooting in Intrinsically Safe circuits must be approved for the intended use. 2-1

Chapter 2 Explosion Protection Techniques 2.2 Flameproof/Explosion Proof Flameproof/Explosion proof enclosures can be used when an explosion is allowed inside the enclosure as long as it does not spread to the outside. The enclosure must be strong enough to withstand the pressure and must have narrow gaps to allow the pressure to escape without igniting the atmosphere outside the equipment. Note! The flameproof/explosionproof enclosure must not be opened while the unit is powered or when an explosive gas atmosphere is present. Damaged enclosures must be taken out of service. All cover fastening screws must be present and firmly tightened. 2.3 Increased Safety This type of protection is intended for products in which arcs and sparks do not occur in normal service nor under fault conditions, and in which excessive surface temperatures are prevented. Increased Safety is achieved by enhancing insulation values and creepage and clearance distances above those required for normal service, thus providing a safety factor against accidental breakdown. Electrical connections are carried out in such a way that self-loosening is not possible. 2-2

For Ccable and Lcable, if the capacitance per foot or the inductance per foot is not known, then the following values shall be used: Ccable = 60pF / foot and Lcable = 0.2uH / foot. Note 7.The outputs at W12 are intrinsically safe "ia" for use in Class I, Zone 1, Group IIB; Class I, Division 1, Groups C and D Hazardous Locations. Note 6. The radar unit must not be powered by or connected to equipment that uses or generates more than 250V RMS with respect to earth ground. Note 5. The ground of the radar unit must be connected to earth ground of the AC feeder supply circuit. The resistance between the ground lug and the earth ground must be less than 1 ohm. Note 4. The intrinsically safe wiring must be in accordance with the National Electrical Code ANSI/NFPA 70, NEC Article 504 and ANSI/ISA RP12.6. In Canada, the installation must be in acordance with the Canadian Electrical Code, CEC Part 1. Note 3.
