Safety and hazard information
Please note that electrotechnical work may only be carried out by qualified electricians or under their guidance and supervision. Observe any deviating country-specific electrical installation standards and regulations and seek advice from a local electrician.In addition, observe more current safety instructions and regulations for the products on the manufacturer's side or the product descriptions and installation instructions on the manufacturer's side.

Devices with a connected load of > 380V/400V require a heavy current connection and may only be connected by an approved electrical company. Devices with a power rating > 12kW require the approval of your grid operator (Germany, other countries may differ).

KNX system description The KNX system is a flexible, upwardly compatible installation bus system (formerly EIB = European Installation Bus) for use in building system technology. It is specifically tailored to special requirements in terms of comfort, the possibility of flexible use of space, the combination of central and decentralized control, the intelligent linking of trades and systems, communication options, environmental compatibility, minimizing energy and operating costs as well as the functions of display, reporting and operation , monitoring and detecting. Thanks to its decentralized structure, it enables building-specific operational management in residential and functional buildings, regardless of the size of the system. The use of commercially available circuit distributors and installation boxes is particularly advantageous. All bus participants are connected via a bus line that complies with the KNX guidelines (Konnex Association) (e.g. JY(St)Y 2x2x0.8). Since the bus cable, according to DIN VDE 0100, can be laid directly next to power lines, the cable routing is greatly simplified. Compared to public telecommunications systems, the bus system with all components must be treated like a high-voltage system. As with high-current installations, the cable routing can be designed in a star or tree shape. A combination of the different cable routings is generally permitted. The wiring is done using two-wire technology, with the wires colored red (for +) and black (for -) representing the preferred wires. The white and yellow wires serve as reserves. The participants are supplied with the bus voltage (safety extra-low voltage SELV 30 V DC) via the bus line. At the same time, it serves to transmit the information that is exchanged between the bus participants. A terminating resistor is not required for the bus line. The smallest unit in the KNX system is a participant. Each participant consists of a user module (AM) and a bus coupler (BA). AM and BA are connected to each other via the user interface (AST). Up to 64 participants can be connected to one line. Twelve lines can be connected to each other via line couplers and thus combined into one area. Up to 15 of these areas can be connected to each other via area couplers. Project planning, parameterization, commissioning and diagnostics are carried out using the ETS (EIB tool software). The documentation of the system is also created using the ETS. As part of the project planning, each participant is assigned a unique physical address. This consists of the number of the area, the line and the participant within the line. During commissioning, this physical address is first loaded into the BA. For this purpose, the PC is connected to the bus at any point in the system via a data interface (USB). All BAs of a KNX system with the assigned applications from the manufacturer database are programmed using the physical addresses. Each BA contains an EEPROM in which the physical address and the application are stored. In this way, the KNX system is protected against data loss in the event of a power failure. The following conditions apply when installing the KNX system: - The total length of all cables laid in a bus line must not exceed a length of 1000 m! - The maximum length between two bus devices is 700 m! - The maximum cable length between the power supply (including choke) and each bus participant must not exceed 350 m! - In order to avoid EMC interference caused by overvoltages, make sure that the bus line does not form a closed loop at any point in the system! - The project planning and parameterization as well as the commissioning and diagnosis of a KNX bus system requires precise product knowledge with regard to the functionality of the system. Therefore, all of the above-mentioned work may only be carried out by trained people.
