Electrical Cabinet Placement

Depending on space requirements and availability, you can install everything in a central consumer unit or split it up over sub-consumer units. Normally, it is advantageous to combine the cellar, ground floor and outdoors area in a single consumer unit and put the electronics for the first floor in a smaller sub-consumer unit on the first floor. Using sub-consumer units reduces the length of cables and thus substantially reduces the cabling effort and simplifies the feeding in of cables.

You will need a bus extension module for every sub-consumer unit to connect the evonHOME modules to one another. You also need a bus extension module (Sys 1200) each time you start a new row within a consumer unit.

A separate 24 V supply is not always required for a sub-consumer unit. If the power is sufficient, you can route the supply from a previous unit.

Example:
Since the bedroom is on the first floor, we will use a sub-consumer unit. The power supply and the evonHOME controller are placed into the main consumer unit and the bus extension and the module for the bedroom in the sub-consumer unit. Both consumer units are connected to each other with the bus cable (CAT5) and the 24V power supply cable.
