For the wiring and connection of the controller, you are required to observe the regulations of the Association of German Electrical Engineers (VDE) and your local power supplier. For this reason, this type of work must be carried out by a specialist. Caution! The controller inputs are not DC-isolated from the control outputs.
  • Page 87 Electrical connection Connecting the controller Connect the controller as shown in Fig. 30. Note! It is important to observe the system code number and the configuration. 1. Open the casing. 2. Make holes to feed through cables at the marked locations on the top, bottom or back of the rear casing.
