Where should the low-voltage cable from the wall inlets be connected?
The low-voltage cable from the wall inlets must be connected to the terminals on the central vacuum cleaner’s control board. These connection points are usually clearly marked and easily accessible on the unit. The cable must be connected to both terminals, and polarity does not matter. Make sure the connection is secure, that the cable is not pinched, and consider fastening it along the pipe system using cable clips. A detailed illustration of the correct connection can be found in the installation manual, typically shown on page 13.
