Safety regulations 1 Safety regulations This section describes the danger levels and the relevant safety regulations applicable to the use of the products described in this manual. Please read the following work instructions as well as the preceding section About this document thoroughly before beginning any work. Danger potential to individuals NK82xx units are powered with low voltage DC.
Safety regulations 1.4 Disposal and recycling These devices include electrical and electronic components and must not be disposed of as domestic waste. Current local legislation must be observed. The NK8000 units have been manufactured as much as possible from materials that can be recycled or disposed of in a manner that is not environmentally damaging.
Introduction 2 Introduction This section provides a description of an NK8000 system and its components. 2.1 NK8000 system overview The NK8000 family provides LAN/WAN adapter products for a safety and security network, which is based on TCP/IP, BACnet/IP, and Ethernet standards. It works together with Siemens Danger Management Systems (DMS) to manage distributed safety and security units.
Introduction 2.2 Interactions Local interactions Interactions are possible between the subsystems connected to each NK82xx unit and the locally connected I/O modules. Incoming messages can trigger one or more command messages to other subsystems. Thanks to the high reliability of the NK82xx units, these interactions are more secure than reactions and sequences programmed on the management station level.
