1 TI00K/09/EN/ Products Solutions Services Technical Information HAW56 Surge arresters for DIN rail according to EN 6075 Application Surge arresters are used to weaken residual currents from upstream lightning protection steps and to limit system-induced or system-generated overvoltage surges. HAW56 units are primarily used in process automation and in measuring and communication technology within the chemicals, pharmaceuticals, water and wastewater sectors as well as in the food industry. Your benefits Increased plant availability as surge arrester is perfectly matched to the electronic components involved in process automation and process measuring technology. Application in Ex areas - optionally available with intrinsically safe approvals. SIL (optional) Direct and indirect shield grounding Investment intensive measuring instruments protected. Vibration and shock tested according to EN

2 HAW56 Function and system design Operating principle Available versions The HAW56 surge arrester is used to protect electronic components from being destroyed by overvoltage. It ensures that overvoltage surges which occur in signal cables (e.g. to 0 ma), in communication lines (Field buses) and in power lines are safely passed into the ground. The functionality of the transmitter or the electronics component to be protected is not affected. Operation of power supply protection units: Using the impedance-free connection of the protection unit, interference voltage drops cannot be introduced on the power lines. Operation of signal cable protection units: Low and matched disconnection impedance between the individual protection steps within the unit guarantee high compatibility with the system to be protected. For power lines: HAW56-AAB to protect power lines in non-ex areas, voltage range 0-55 V HAW56-AAC to protect power lines in non-ex areas, voltage range V For signal cables and communication lines: HAW56-AAA to protect signal cables in non-ex areas HAW56-8DA with Ex ia approval to protect signal cables HAW56-AAD to protect communication lines (RS85, Modbus, Profibus DP) in non-ex areas HAW56-AAE protection module for Prosonic FMU90 in non-ex areas System construction Field device HAW56-AAB/-AAC Power supply HAW569 -CBC HAW56-AAA/ -AAE/-8DA I/O HAW569 -AAB/-DAB Cabinet Field device, e.g. temp. sensor Overview of system construction, HAW56 and HAW569 A0053-EN Application Overvoltage protection of various measurement instrumentation seen in the example of a water treatment plant. Conditions for the installation of surge arresters in a water treatment plant are: Lightning protection of plant and buildings Lightning protection of the main power supply distribution circuits in accordance with local regulations Low impedance foundation grounding Linked grounding of all buildings and plant (, 3)

The shielding should be grounded by means of direct shield grounding at least at both ends of the cable. If direct grounding of the shield at both ends is not possible or desired, e.g. to avoid low-frequency equalizing currents, indirect shield grounding should be provided at one end. Equalizing currents are thus avoided yet EMC requirements are still met. Indirect shield grounding occurs via a gas discharge tube installed in the overvoltage protection module.

In the event of a defect (= red display window - means thermal overload) this monitoring system will automatically separate the surge arrester from the power source. All other HAW56 units do not have any display elements. NOTICE Defective surge arrester Electric units connected are then no longer protected from overvoltages. Replace surge arrester immediately. HAW56-AAA, HAW56-AAD, HAW56-AAE, HAW56-8DA These units do not have any display elements. NOTICE Defective surge arrester Signal cable short circuit. The short circuit is rectified when the defective protection module is taken out of the carrier. Electric units connected are no longer protected from overvoltages.
