Terminate all branches of the wiring system via a connected bus device (e.g., indoor station,
outdoor station, system device).
Do not install the system controller directly next to the bell transformer and other power
supplies (to avoid interference).
Do not install the wires of the system bus together with 100-240 V wires.
Do not use common cables for the connecting wires of the door openers and wires of the
system bus.
Avoid bridges between different cable types.
Use only two wires for the system bus in a four-core or multi-core cable.
When looping, never install the incoming and outgoing bus inside the same cable.
Never install the internal and external bus inside the same cable.
