By arranging the Clamps in or on the base part, this also serves for electrical connection of the system module and the control electronics, so that separately arranged terminals can be omitted. Because of this simple way of de-energizing, you can individual system modules for maintenance purposes, repairs or the like quickly and safely disconnected from the electrical system.
  • the plug-in module is also very compact and can be carried by maintenance personnel to prevent the system module from being accidentally switched on again. This is particularly important if the system module is relatively far away is arranged by base part and plug-in module, which is usually the case.
