Home automation installation notes

The general rules for installation are those provided for by the standard in force, in particular those on distances with other systems or appliances.
Ducts are generally laid after the other systems such as heating/air conditioning, hydraulic and sanitary systems, central vacuum system, etc.
In the case of a floor-mounted heating system, ducts are laid before it and under the heating pipes to prevent overheating of cables.
All cables must be installed in compliance with the project instructions of the system and the standards in force to guarantee proper insulation between power supply cables and signal cables to prevent disturbances.

Provided that they are not in conflict with the directions above, the following instructions must also be followed:
- cables must be laid in a way to reduce interfereces and disturbances;
- keep the greatest possible distance between interfearing cables (for ex. EMF, antennas, etc.) and AVEbus cables which must not be subject to interference;
- do not install disturbing cables and cables which must not be subject to disturbance side by side and in case of intersection it must be made perpendicularly;
- use twisted and shielded signal wires to limit electromagnetic emissions and increase immunity, bus cable sup- plied by AVE S.p.A. item CVAVEBUS;
- Wiring must be carried out properly in compliance with the rules for traditional systems and provided for by the current standards.

The sizing of the system must take account of the following:
- The maximum number of domotic devices installed on the bus line must not be greater than C=300 (maximum load of the bus line, for sizing refer to table page 101 and the technical sections at;
- the total capacity of the devices connected to the line must not be greater than 150nF (500 devices on the same bus line);
- the maximum distance between AVEbus power supply unit and the farthest away device must not be greater than 300 m.
