Safety and EMC optimization

2.1 Notes on safety

This section explains general and system-specific regulations for mains and

operating voltages. It includes important information for your safety and the safety

of the entire plant.
Please comply with the following general regulations during engineering and

execution:

•

Electrical and mains power ordinances for the given country.

•

Other applicable, national regulations.

•

Building installation regulations for the given country.

•

Regulations of the utility company.

•

Diagrams, cable lists, dispositions, specifications, and orders by the customer or

authorized engineering office.

•

Third-party regulations, e.g. by the general contractor or building owner.

The electrical safety for building automation and control systems by Siemens is

essentially based on

safely separating low voltage from mains voltage.

2.2 Device-specific regulations

Note permissible line lengths and topologies when planning and installing

controllers and field devices featuring KNX bus connection. Make sure the bus

supply complies with the KNX standard.

Do not open the device.

The device is maintenance free. Only the manufacturer can repair the device.

2.3 Notes on EMC optimization

When setting up cable ducts, separate strongly interfering cables from susceptible

entities.

•

Interfering cables: Motor cables especially from motors supplied by inverters,

energy-supplying cables.

•

Susceptible entities: Control cables, low voltage cables, interface cables, LAN

cables, digital and analog signal cables.

•

Both types of cables may be in the same cable duct, but in separate

compartments.

•

If no three-sided, closed duct with separating wall is available, the interfering

cables must be separated by at least 150 mm from the others or placed in

separate ducts.

•

Crossings of strongly interfering cables with possibly susceptible entities must

be at a right angle.

•

In exceptional cases, signal and interfering power cables may be run in parallel,

resulting in a high interference risk.

We recommend to generally use unscreened cables. Comply with the

manufacturer's installation recommendations for selecting unscreened cables. In

general,

unshielded twisted pair cables

have sufficient EMC properties for

technical building applications (including data applications) and do not require

consideration of coupling to surrounding earth.

Please comply
