TECHNICAl INFORMATION
• Cables carrying mains voltage must be routed sepa-
rately from sensor or data bus cables. A minimum di-
stance of 2 cm between the cables must be observed.
Cable crossovers are permitted.

• In the case of controller modules with their own mains
supply, it is imperative that cables carrying mains vol-
tage are routed separately from sensor or data bus
cables. If cable ducts are used, these must be provided
with separator strips.
• When mounting controller modules or room control mo-
dules, maintain a minimum clearance of 40 cm from
other electrical devices with electromagnetic emissi-
ons, such as power contactors, motors, transformers,
dimmers, microwave ovens and TV sets, loudspeakers,
computers, mobile phones, etc.

• Avoid unnecessary cable lengths, including in spare cables
• Coils of relays, contactors and other inductors in the pa-
nel, and possibly in the vicinity, must be connected. The
connection can be made with RC elements, for example.
• Measures must be taken in the building and on electri-
cal equipment to protect the units against overvoltage
caused by lightning strikes.
• The mains connection for the heating system must be
designed as an independent electrical circuit. Neither
fl uorescent lamps nor any other equipment which might
cause interference may be connected, nor may it be
possible to connect such equipment.

• Equipotential bonding must be established between the
individual control components, control panels and the
heating system.
• Shielded cables must be used for the data lines.
Recommended versions:
J-Y(ST)Y 2 x 2 x 0.6 mm
• Shields of data lines, analogue signal cables and power
cables must be connected to earth over a large area
with a highly conductive connection. The cable shields
must be connected to a shield bar directly after the ent-
ry of the cable into the panel.
• Multiple earthing of a cable is not permitted (ripple pickup).
