the absolute shaft encoders of the type ra 58/59 model series are quality products manufactured in accordance with established electrical engineering standards. the units have been delivered from the factory in perfect conformance to safety regulations. to maintain this condition and to ensure trouble-free operation, please observe the technical specifications of this document. ? installation and mounting may only be performed by an electrotechnical expert! ? the units may only be operated within the limits specified by the technical data. ? maximum operating voltages must not be exceeded! the units are designed complying with din en 61010-part 1, protection class iii. to prevent dangerous structure-borne currents, the equipment has to be run on safety extra-low voltage (selv) and must be in an area of equipotential bonding. use an external fuse for protection (see electrical data). ? fields of application: industrial processes and controls. overvoltage at the connecting terminals must be limited to overvoltage class-ii values. ? please avoid shocks to the housing C especially to the encoder shaft C and axial or radial overload to the encoder shaft. ? maximum accuracy and durability of our shaft encoders is only granted with suitable couplings. ? the high-quality emc-specifications are only valid together with standard- type cables and plugs. when using screened cables, the screen must broadly be connected with ground on both ends. also the voltage supply lines should be screened completely. if this is not possible, the corresponding filter mea- sures are to be taken. ? installation environment and wiring have a significant impact on the encoder's emc: thus the installer must secure emc of the whole facility (device). ? in electrostatically threatened areas please take care for neat esd-protection of plug and connecting cable during installation work.
