Safety measures for EMC - conform installation

• Cables with mains voltage must generally be installed separately from sensor and data bus cables. In
this case a minimum distance of 2 cm between the cables must be observed. Crossing of lines is
permitted.

• Controls with own mains connections require a separate installation of mains and sensor or data bus
cable. When using cable ducts, types with internal separators are recommended.
• When installing control or remote units close to other components with electro magnetic emission such
as solid state relays, motors, transformers, dimmers, micro wave ovens, TV-sets, loudspeakers,
computers, radio telephones etc. a minimum distance of 40 cm must be observed.

• Between remote units and standard units, a minimum distance of 40 cm has to be observed. Several
standard units in a data bus connection may be installed side by side.
• The mains connection of the heating plant (standard unit or boiler control panel) must be carried out as
an independent electric circuit. It is not permitted to install fluorescent tubes or other machines that could
produce interferences to the same electrical circuit.
