Hirschmann MM20-P9P9P9P9SAHH In installation instructions

Important information 

 Note: Read these instructions carefully, and familiarize yourself with the device before trying to install, operate, or maintain it. The following notes may appear throughout this documentation or on the device. These notes warn of potential hazards or call attention to information that clarifies or simplifies a procedure.  Symbol explanation This is a general warning symbol. This symbol alerts you to potential personal injury hazards. Observe all safety notes that follow this symbol to avoid possible injury or death. If this symbol is displayed in addition to a safety instruction of the type “Danger” or “Warning”, it means that there is a danger of electric shock and failure to observe the instructions will inevitably result in injury. This symbol indicates the danger of hot surfaces on the device. In connection with safety instructions, non-observance of the instructions will inevitably result in injuries.

Safety instructions

UNCONTROLLED MACHINE ACTIONS To avoid uncontrolled machine actions caused by data loss, configure all the data transmission devices individually. Before you start any machine which is controlled via data transmission, be sure to complete the configuration of all data transmission devices. Failure to follow these instructions can result in death, serious injury, or equipment damage

Certified usage 

  Use the device solely for the application cases described in the Hirschmann product information, including this manual. Operate the device solely according to the technical specifications. 

  Supply voltage The devices are designed for operation with Safety Extra-low Voltage (SELV). Connect only SELV circuits with voltage restrictions according to IEC 60950-1 or ES1 according to IEC/EN 62368-1 to the supply voltage connections and to the signal contacts. The supply voltage is electrically isolated from the housing. 

  Use undamaged parts. 

  For power supply via DC voltage: All following prerequisites are fulfilled: 

  There are fuses suitable for DC voltage in the positive conductors of the supply lines, or the voltage sources are appropriately current limited. Regarding the properties of this fuse: See “General technical data” on page 67. 

  The negative conductors of the voltage inputs are on ground potential. 

  For power supply via AC voltage: All following prerequisites are fulfilled: 

  There are fuses in the supply lines, or the voltage sources are appropriately current-limited. Regarding the properties of this fuse: See “General technical data” on page 67. 

  The power sources are electrically isolated from the ground

  Relevant for North America: The device may only be connected to a Class 2 supply voltage that fulfills the requirements of the National Electrical Code, Table 11(b). If the voltage is being supplied redundantly (two different voltage sources), the combined supply voltages must fulfill the requirements of the National Electrical Code, Table 11(b). 

  Relevant for North America: For use in Class 2 circuits. Only use copper wire/conductors of class 1, 75 °C (167 °F). Start connecting the electrical wires only if all the above safety requirements are fulfilled

Use in Hazardous Locations

Relevant for North America for modules certified for Hazardous Locations: This equipment is suitable for use in Class 1, Division 2, Groups A, B, C and D or Non-Hazardous (unclassified) locations only. Make sure that peripheral devices are suitable for the application environment. The wiring for the voltage supply and for the inputs and outputs (I/O) must adhere to the wiring regulations for Class 1, Division 2 [article 501(b) of the National Electrical Code (USA), NFPA 70] and to the applicable statutory regulations. Note: Observe the control drawing (document number 000160011DNR) on the following pages. Avertissement - Risque d'explosion - Ne pas débrancher tant que le circuit est sous tension à moins que l'emplacement soit connu pour ne contenir aucune concentration de gaz inflammable. Avertissement - Risque d'explosion - La substitution de tout composant peut rendre ce matériel incompatible pour une utilisation en classe I, division 2
