Distribution in the connections
· The Scena system is installed mainly using two very different types of connections.
- Communications cable: includes power and data. It must be a flexible, multicore FTP cat5 cable.
- Power cable: fundamental for the regulator as it supplies voltage for its operation.
As can be seen in the picture, the power part is
formed be means of:
- Powering of the 230V F and N regulator
(depending on the module).
- Module output to load, depending on the module
- Push-button auxiliary input.
As can be seen in the picture, the communications part is connected by means of:
- The power part of 12V (12V, GND), supplied from
the central console or from power source
Ref. 8999901-039.
- The data part (A, B) through which the communi-
cation data will be sent.
The grid must be connected to a point of the installation (-) and maintain continuity by bridging on the
other devices.
