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
The power supply unit and additional devices are 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 "
* ".
