General Information

Cable networks

Existing lines can be used as bus lines. We recommend the following, commercially avail-

able lines:

• CAT 1 (for audio)

•CAT 3

• Telecommunication line J-Y (St) Y

• Telecommunication line J-2Y (z) Y with strain-relief

• Telecommunication grounding cable, longitudinally and transversally waterproof

Cable layout

It is recommended to lay the bus line from subscriber to subscriber and to connect it to the

connection terminal on the device.

All the line screening sheaths and free wires must be connected across the joints and laid

to Terminal b on the TwinBus power supply unit. Please use appropriate locally provided

terminals for this.
