The article numbers of RITTO products are made up of three components. For example, 1 7630 70

1 7630 xx Device: TwinBus indoor telephone

7 x Colour: white

x 0 Device index

This document only specifies information on the respective device. Please refer to the manual for the colours

available and the current device versions.

General Information

1.1 Cable networks

Existing lines can be used as bus lines. We recommend the following, commercially available telecommunication

lines:

Telecommunication line J-Y (St) Y

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

Telecommunication grounding cable, longitudinally and transversally waterproof

For more information, please refer to the planning manual.

1.1.1 Cable layout

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

device.

All the line screening sheaths 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.

The stranded video line Va/Vb can generally be laid in the cable with the screened a/b lines.

In order to fulfil the general safety requirements for telecommunication systems complying to VDE 0800 and prevent

disturbances on the lines, ensure that the mains voltage and SELV (TwinBus line) are laid separately. A clearance of

10 cm must be maintained for the installation. In the case of a common line cabling, a separating webbing must be

inserted in the installation channels.

The bus lines must be terminated with terminal resistors.

Please follow the installation instructions for the indoor video stations 1 7855, 1 7857 or the handsfree video intercom

units 1 7835 and 1 7845.

1.1.2 Maximum line lengths

The loop resistance of each TwinBus line must not exceed max. 20 Ohm. This results in the following maximum line lengths:

Line lengths for 75 ΩCOAX lines

Caution!

Malfunctions due to strong magnetic fields

No other devices with strong magnetic field (contactors, transformers, etc.) may be installed in the

direct vicinity of the power supply unit and additional devices. Malfunctions could be caused by

induced voltage peaks.

General Information

1.1.3 Considerations when renovating

If commercially available doorbells are used, they must not have a contact transition resistance in excess of 10 Ohm.

1.1.4 Connection to the mains

Please note that a 230 V/AC power supply is required for the power supply units and mains transformers which are

not explicitly depicted in the block diagrams.

1.1.5 Electrostatic charging

1.2 The system bus

Thepowersupplyunitandadditionaldevicesare connected via the system bus. The system bus connector, enclosed

with each additional device, is used for this purpose.

1.3 Bus connector in the Portier modular door station

The door station modules are connected to the bus connectors one under the other.

Note:

In the case of existing YR cables, all the free wires on the TwinBus power supply unit must be laid

as screening to Terminal b.

Caution!

Equipment damage through overvoltage or short circuiting

Equipment damage can occur through overvoltage or short circuiting. Connection must be made to

a 230 V~±10% mains power outlet. The power must be fed via an intrinsic line safety switch with

max.10 A.

Caution!

Risk of equipment damage through static electricity (ESD)

Static electricity could destroy equipment if direct contact is made with the printed circuit boards.

Discharge electrostatic charges before touching the equipment.

1. TwinBus power supply unit 1 7573

2. System bus connector

3. TwinBus additional device

The additional devices receive their power supply via the

system bus.

If the devices are installed on several mounting rails, the

bus connector 1 6907 is used instead of the system bus

connector.

Connection is made from the right-hand system bus

connection of the device to the left-hand system bus

connection of the following device.

The wire of the bus connector in the door station marked

red must be attached to the pin labelled "red" on the

board. As a result, the door station modules are

numbered identically. The wire marked red is identified in

the respective circuit diagram by a "*".
