3.2.2 Electrical connection for wall mounting
BBUS connection from the controller to other
BUS subscribers:
Use electrical cable according to local codes
and requirements.
Permissible cable lengths from the BUS-enabled
Heatronic 3 to the controller:
BTo prevent inductive interference: Route all LV
leads separately from cables carrying 220 to
240 V or 380 to 415 V (minimum separation
100 mm).
BIn case of external inductive interference,
shield the cables.
This ensures that the cables are shielded from
external interference (e.g. heavy current
cables, overhead wires, transformer stations,
radio and television set, amateur radio
stations, microwave ovens etc).
