    1 Safety 1.1 General Potential for Danger The SSI-BOX cannot function as a stand-alone unit, i.e. it is a component part that is intended to be installed in a complete system consisting of several such components working together. This means that the SSI-BOX does not have a direct protection device of its own.

  • Page 7: Installation Information

    Operating Manual SSI-BOX PROFIBUS-DP (PNO) 1.2.1 Installation information Due to the fact that the SSI-BOX is normally used as a component part of a larger system, this information is intended to provide a guideline for safe installation of the device in its environment.
