12 3-6 Safety Instructions for Electric Servo Drives and Controls PROFIBUS Coupler 3.5 Protection against contact with electrical parts Note: This section refers to equipment with voltages above 50 Volts. Making contact with parts conducting voltages above 50 Volts could be dangerous to personnel and cause an electrical shock. When operating electrical equipment, it is unavoidable that some parts of the unit conduct dangerous voltages. DANGER High electrical voltage! Danger to life, severe electrical shock and severe bodily injury! Only those trained and qualified to work with or on electrical equipment are permitted to operate, maintain or repair this equipment. Follow general construction and safety regulations when working on electrical installations. Before switching on power the ground wire must be permanently connected to all electrical units according to the connection diagram. Do not operate electrical equipment at any time if the ground wire is not permanently connected, even for brief measurements or tests. Before working with electrical parts with voltage potentials higher than 50 V, the equipment must be disconnected from the mains voltage or power supply. The following should be observed with electrical drives, power supplies, and filter components: Wait five (5) minutes after switching off power to allow capacitors to discharge before beginning work. Measure the voltage on the capacitors before beginning work to make sure that the equipment is safe to touch. Never touch the electrical connection points of a component while power is turned on. Install the covers and guards provided with the equipment properly before switching the equipment on. Prevent contact with live parts at any time. A residual-current-operated protective device (r.c.d.) must not be used on an electric drive! Indirect contact must be prevented by other means, for example, by an overcurrent protective device. Equipment that is built into machines must be secured against direct contact. Use appropriate housings, for example a control cabinet. European countries: according to EN 50178/1998, section U.S.A: See National Electrical Codes (NEC), National Electrical Manufacturers Association (NEMA) and local building codes. The user of this equipment must observe the above noted instructions at all times.

13 PROFIBUS Coupler Safety Instructions for Electric Servo Drives and Controls 3-7 To be observed with electrical drives, power supplies, and filter components: DANGER High electrical voltage! High leakage current! Danger to life, danger of injury and bodily harm from electrical shock! Before switching on power for electrical units, all housings and motors must be permanently grounded according to the connection diagram. This applies even for brief tests. Leakage current exceeds 3.5 ma. Therefore the electrical equipment and units must always be firmly connected to the supply network. Use a copper conductor with at least 10 mm² cross section over its entire course for this protective connection! Prior to startups, even for brief tests, always connect the protective conductor or connect with ground wire. High voltage levels can occur on the housing that could lead to severe electrical shock and personal injury. European countries: EN 50178/1998, section USA: See National Electrical Codes (NEC), National Electrical Manufacturers Association (NEMA), and local building codes. The user of this equipment must maintain the above noted instructions at all times.

14 3-8 Safety Instructions for Electric Servo Drives and Controls PROFIBUS Coupler 3.6 Protection by protective low voltage (PELV) against electrical shock All connections and terminals with voltages between 5 and 50 Volts on INDRAMAT products are protective low voltages designed in accordance with the following standards on contact safety: International: IEC EU countries: see EN 50178/1998, section WARNING High electrical voltage due to wrong connections! Danger to life, severe electrical shock and severe bodily injury! Only equipment, electrical components and cables of the protective low voltage type (PELV = Protective Extra Low Voltage) may be connected to all terminals and clamps with 0 to 50 Volts. Only safely isolated voltages and electrical circuits may be connected. Safe isolation is achieved, for example, with an isolating transformer, an optoelectronic coupler or when battery-operated. 3.7 Protection against dangerous movements Dangerous movements can be caused by faulty control or the connected motors. These causes are be various such as: unclean or wrong wiring of cable connections inappropriate or wrong operation of equipment malfunction of sensors, encoders and monitoring circuits defective components software errors Dangerous movements can occur immediately after equipment is switched on or even after an unspecified time of trouble-free operation. The monitors in the drive components make faulty operation almost impossible. Regarding personnel safety, especially the danger of bodily harm and property damage, this alone should not be relied upon to ensure complete safety. Until the built-in monitors become active and effective, it must be assumed in any case that some faulty drive movements will occur. The extent of these faulty drive movements depends upon the type of control and the state of operation.

15 PROFIBUS Coupler Safety Instructions for Electric Servo Drives and Controls 3-9 DANGER Dangerous movements! Danger to life and risk of injury or equipment damage! Personnel protection must be secured for the above listed reason by means of superordinate monitors or measures. These are instituted in accordance with the specific situation of the facility and a danger and fault analysis conducted by the manufacturer of the facility. All the safety regulations that apply to this facility are included therein. By switching off, circumventing or if safety devices have simply not been activated, then random machine movements or other types of faults can occur. Avoiding accidents, injury or property damage: Keep free and clear of the machine s range of motion and moving parts. Prevent people from accidentally entering the machine s range of movement: - use protective fences - use protective railings - install protective coverings - install light curtains or light barriers Fences must be strong enough to withstand maximum possible momentum. Mount the emergency stop switch (E-stop) in the immediate reach of the operator. Verify that the emergency stop works before startup. Don t operate the machine if the emergency stop is not working. Isolate the drive power connection by means of an emergency stop circuit or use a start-inhibit system to prevent unintentional start-up. Make sure that the drives are brought to standstill before accessing or entering the danger zone. Secure vertical axes against falling or slipping after switching off the motor power by, for example: - Mechanically securing the vertical axes - Adding an external brake / clamping mechanism - Balancing and thus compensating for the vertical axes mass and the gravitational force The standard equipment motor brake or an external brake controlled directly by the servo drive are not sufficient to guarantee the safety of personnel!

16 3-10 Safety Instructions for Electric Servo Drives and Controls PROFIBUS Coupler Disconnect electrical power to the equipment using a master switch and secure the switch against reconnection for: - maintenance and repair work - cleaning of equipment - long periods of discontinued equipment use Avoid operating high-frequency, remote control and radio equipment near electronics circuits and supply leads. If use of such equipment cannot be avoided, verify the system and the plant for possible malfunctions at all possible positions of normal use before the first start-up. If necessary, perform a special electromagnetic compatibility (EMC) test on the plant. 3.8 Protection against magnetic and electromagnetic fields during operations and mounting Magnetic and electromagnetic fields generated by current-carrying conductors and permanent magnets in motors represent a serious health hazard to persons with heart pacemakers, metal implants and hearing aids. WARNING Health hazard for persons with heart pacemakers, metal implants and hearing aids in proximity to electrical equipment! Persons with pacemakers, metal implants and hearing aids are not permitted to enter following areas: - Areas in which electrical equipment and parts are mounted, being operated or started up. - Areas in which parts of motors with permanent magnets are being stored, operated, repaired or mounted. If it is necessary for a person with a pacemaker to enter such an area, then a physician must be consulted prior to doing so. Pacemaker, that are already implanted or will be implanted in the future, have a considerable deviation in their resistance to interference. Due to the unpredictable behavior there are no rules with general validity. Persons with hearing aids, metal implants or metal pieces must consult a doctor before they enter the areas described above. Otherwise health hazards will occur.

17 PROFIBUS Coupler Safety Instructions for Electric Servo Drives and Controls Protection against contact with hot parts CAUTION Housing surfaces could be extremely hot! Danger of injury! Danger of burns! Do not touch surfaces near the source of heat! Danger of burns! Wait ten (10) minutes before you access any hot unit. Allow the unit to cool down. Do not touch hot parts of the equipment, such as housings, heatsinks or resistors. Danger of burns! 3.10 Protection during handling and installation Under certain conditions unappropriate handling and installation of parts and components may cause injuries. CAUTION Risk of injury through incorrect handling! Bodily harm caused by crushing, shearing, cutting and mechanical shock! Observe general instructions and safety regulations during handling installation. Use only appropriate lifting or moving equipment. Take precautions to avoid pinching and crushing. Use only appropriate tools. If specified by the product documentation, special tools must be used. Use lifting devices and tools correctly and safely. Wear appropriate protective clothing, e.g. safety glasses, safety shoes and safety gloves. Never stay under suspended loads. Clean up liquids from the floor immediately to prevent personnel from slipping.

18 3-12 Safety Instructions for Electric Servo Drives and Controls PROFIBUS Coupler 3.11 Battery safety Batteries contain reactive chemicals in a solid housing. Inappropriate handling may result in injuries or equipment damage. CAUTION Risk of injury through incorrect handling! Do not attempt to reactivate discharged batteries by heating or other methods (danger of explosion and corrosion). Never charge batteries (danger from leakage and explosion). Never throw batteries into a fire. Do not dismantle batteries. Handle with care. Incorrect extraction or installation of a battery can damage equipment. Note: Environmental protection and disposal! The batteries contained in the product should be considered as hazardous material for land, air and sea transport in the sense of the legal requirements (danger of explosion). Dispose batteries separately from other refuse. Observe the legal requirements given in the country of installation Protection against pressurized Systems Certain Motors (ADS, ADM, 1MB etc.) and drives, corresponding to the information in the Project Planning manual, must be provided with and remain under a forced load such as compressed air, hydraulic oil, cooling fluid or coolant. In these cases, improper handling of the supply of the pressurized systems or connections of the fluid or air under pressure can lead to injuries or accidents. CAUTION Danger of injury when pressurized systems are handled by untrained personnel! Do not attempt to disassemble, to open or to cut a pressurized system. Observe the operation restrictions of the respective manufacturer. Before the disassembly of pressurized systems, lower pressure and drain off the fluid or gas. Use suitable protective clothing (for example protective eyewear, safety shoes and gloves) Remove any fluid that has leaked out onto the floor immediately. Note: Environmental protection and disposal! The fluids used in the operation of the pressurized system equipment is not environmentally compatible. Fluid that is damaging to the environment must be disposed of separate from normal waste. Observe the national specifications of the country of installation.

19 PROFIBUS Coupler PROFIBUS Coupler R-IL PB BK PROFIBUS Coupler R-IL PB BK 4.1 Presentation and Application Characteristics Fig. 4-1: Module R-IL PB BK with clipped-on connector and end plate 6137a002.eps The PROFIBUS coupler constitutes the link between the PROFIBUS DP and the RECO Inline installation system. At an existing PROFIBUS DP, you can connect Inline modules by means of the PROFIBUS coupler at any location. In this way, you ll be able to benefit from all advantages of the module-structured installation system with the PROFIBUS, too. The PROFIBUS coupler has the following characteristics: A maximum of 63 Inline modules can be connected to the PROFIBUS DP by simply latching them to each other via the coupler. Coupler and Inline module are one station. The total of input and output data of the connected modules may not exceed 192 bytes per station. You can use the coupler with a data transmission speed of 9,6 kbit/s up to 12 MBit/s. The coupler automatically adjusts to the speed set for the PROFIBUS master. The working voltage of the coupler is 24 V DC; the range of operating temperature is 0 C to 55 C. Diagnosis is implemented locally via LEDs both on the coupler and on the Inline and loop-2 modules. Moreover, the PROFIBUS is also used to transmit all diagnosis information to the PROFIBUS master.

20 4-2 PROFIBUS Coupler R-IL PB BK PROFIBUS Coupler Because of the intelligent wiring technology of the RECO Inline modules, the stations can be set up easily and quickly because, for instance, the extensive wiring for supplying the modules with voltage is not applicable any longer. In the easiest case, only the power supply units integrated in the PROFIBUS coupler must be supplied with 24 V DC voltage on their input side. They produce the necessary operation voltages for the PROFIBUS coupler and the connected Inline modules. Note: The connector is not included in the scope of supply of the module. Please order the connector according to the ordering information. The end plate is enclosed with the PROFIBUS DP fieldbus coupler. Place this plate as end cover of the Inline station. This plate does not have any electrical function. It protects the station from ESD pulses and the user from dangerous contact voltage.

Fig. 4-11: Meaning of the DIP switches Note: If DIP switch 8 is set to ON, a POWER DOWN/POWER UP must be implemented on the fieldbus coupler to restart the latter. In other word, there is no automatic restart after the error has been eliminated. System termination resistors Since the PROFIBUS is a serial bus system with star-tree structure, the individual branches must be terminated with a termination resistor. The PROFIBUS coupler itself is not provided with such a resistor. For further information please refer to your PROFIBUS documents. Rexroth Indramat recommends to use a special PROFIBUS connector (mat. no ). This connector is provided with a connectable termination resistor.
