Preparatory steps

Terminate all branches of the wiring system with a connected bus device (e.g., indoor
■
station, outdoor station, system device).
Do not install the central control system directly next to bell transformers and of other
■
switched voltage supplies (avoidance of interference).
Do not install the cores of the system bus together with 100 - 240 V cores.
■
Do not use joint wires for the connecting cables of door openers and wires of the system
■
bus.
Avoid bridges between different wire types.
■
Use only two wires for the system bus in a four-core or multi-core cable.
■
During looping, never install the incoming and outgoing bus within a wire.
■
Never install the internal and external bus within a conduit.
