This icon denotes a caution, which advises you of precautions to take to avoid injury, data loss, or a system crash. When this symbol is marked on the product, refer to the technical reference manual. Indicates hazardous voltages. Indicates the chassis terminal WARNING Calls attention to a procedure, practice, or condition that could cause bodily injury or death. CAUTION Calls attention to a procedure, practice, or condition that could possibly cause damage to equipment or permanent loss of data. DE-M050905E • DEWE-901 • Technical Reference Manual • Printing version 1.0.4 • December 16, 2013 9 Safety instructions Your safety is our primary concern! Please be safe! ! General safety and hazard warnings for all DEWETRON systems Use this system under the terms of the specifications only to avoid any possible danger. If the unit is used in a manner not specified by the manufacturer the protection can be impaired! Ths product is intended for use in industrial locations. As a result, this product may cause interference if used in residential areas. Such use must be avoided unless the user takes special measures to reduce electromagnetic emissions to prevent interferences to the reception of radio and television broadcasts. Maintenance will be executed by qualified staff only. During the use of the system, it might be possible to access another parts of a more comprehensive system. Please read and follow the safety instructions provided in the manuals of all other components regarding warning and security advices for using the system. With this product, only use the power cable delivered or defined for the host country. DO NOT connect or disconnect sensors, probes or test leads, as these parts are connected to a voltage supply unit. The system is grounded via a protective conductor in the power supply cord. To avoid electric shocks, the protective conductor has to be connected with the ground of the power network. Before connecting the input or output connectors of the system, make sure that there is a proper grounding to guarantee potential free usage. For countries, in which there is no proper grounding, please refere to your local legally safety regulations for safety use. DC systems: Every DC system has a grounding connected to the chassis (yellow/green safety banana plug). Please note the characteristics and indicators on the system to avoid fire or electric shocks. Before connecting the system, please carefully read the corresponding specifications in the product manual. The inputs are not, unless otherwise noted (CATx identification), for connecting to the main circuits of category II, III and IV. The measurement category can be adjusted depending on module configuration. The power cord separates the system from the power supply. Do not block the power cord, since it has to be accessible for the users. Supply overvoltage category is II. DO NOT use the system if equipment covers or shields are removed. If you assume the system is damaged, get it examined by authorised personnel only. Any use in wet rooms, outdoors or in adverse environmental condition is not allowed! Adverse environmental conditions are: Moisture or high humidity Dust, flammable gases, fumes or dissolver Thunderstorm or thunderstorm conditions (except assembly PNA) Electrostatic fields, et cetera. Any direct voltage output is protected with a fuse against short cut and reverse-polarity, but is NOT galvanically isolated (except it is explicit marked on the system). The system must be connected and operated to an earthed wall socket at the AC mains power supply only (except for DC systems). Any other use than described above may damage your system and is attended with dangers like shortcut, fire or electric shocks. 10 Safety instructions The whole system must not be changed, rebuilt or opened (except for changing TRION™ modules). If you assume a more riskless use is not provided anymore, the system has to be rendered inoperative and should be protected against inadvertent operation. It is assumed that a more riskless operation is not possible anymore, if the system is damaged obviously or causes strange noises. the system does not work anymore. the system has been exposed to long storage in adverse environmental. the system has been exposed to heavy shipment strain. DO NOT touch any exposed connectors or components if they are live wired. The use of metal bare wires is not allowed. There is a risk of short cut and fire hazard! Warranty void if damages caused by disregarding this manual. For consequential damages NO liability will be assumed! Warranty void if damages to property or persons caused by improper use or disregarding the safety instructions. Unauthorized changing or rebuilding the system is prohibited due to safety and permission reasons (CE). Exception: changing TRION™ modules. The assembly of the system is equivalent to protection class I. For power supply, only the correct power socket of the public power supply must be used, except the system is DC powered. Be careful with voltages >25 VAC or >35 VDC! These voltages are already high enough in order to get a perilous electric shock by touching the wiring. Maximum input voltage for measuring cards are 70 VDC and 46.7 VPEAK The product heats during operation. Make sure there is adequate ventilation. Ventilation slots must not covered! Only fuses of the specified type and nominal current may be used. The use of patched fuses is prohibited. Prevent using metal bare wires! Risk of short cut and fire hazard! DO NOT use the system before, during or shortly after a thunderstorm (risk of lightning and high energy overvoltage). An advanced range of application under certain conditions is allowed with therefore designed products only. For details please refer to the specifications. Make sure that your hands, shoes, clothes, the floor, the system or measuring leads, integrated curcuits and so on, are dry. DO NOT use the system in rooms with flammable gases, fumes or dust or in adverse environmental conditions. Avoid operation in the immediate vicinity of: high magnetic or electromagnetic fields transmitting antennas or high-frequency generators For exact values please refere to enclosed specifications. Use measurement leads or measurement accessories aligned to the specification of the system only. Fire hazard in case of overload! Do not switch on the system after transporting it from a cold into a warm room and vice versa. The thereby created condensation may damage your system. Acclimatise the system unpowered to room temperature. Do not disassemble the system! There is a high risk of getting a perilous electric shock. Capacitors still might charged, even the system has been removed from the power supply.

Disconnect the marked cables (arrows in the picture below) if you just want to pull out the PC-part for 15 centimeters. Unsrew the six screws of the PC-part and pull it out carefully by watching the internal cables. If you want to pull out the PC-part completely you have to disconnect all cables between the system and the PC-part! To add PCI cards you have to unscrew the four screws marked with circles in the picture below. WARNING: The system may only be opened by experts. Disconnect power supply and measurement inputs before opening the system! Touch internal parts only in an ESD protected area!
