2. Installation of Flex2R/2T
Note
This wiring method can be applied in most situations, however, it is only a point of reference. In order to ensure
proper protection, you must always take in to account the specific mechanical and electrical conditions of the
device you are working on.
2.2 Connecting the Flex2R/2T module
As a peripheral, Flex2R/2T must be connected to the control panel through the available ‘
+ D S -
’ terminals.
Terminals ‘SW1’ and ‘SW2’ can be used for connections with both AC and DC powered devices.
Attention!
Dangerous outputs
In normal operating conditions of a ‘SELV’ circuit, the voltage between any two of its conductors or between
any of them and Ground must not exceed 42.4V peak or 60V DC. When these values are exceeded, the vol-
tage is to be considered hazardous.
The installer can choose to use the ‘SW1’ and ‘SW2’ outputs to drive exclusively 2 hazardous voltage devi-
ces or 2 safe voltage devices (SELV). The mixed use of dangerous voltage and safe voltage on these ter-
minals is strictly prohibited.
If the outputs are used on mains (hazardous) voltage, in addition to the above requirements, it is necessary
to take the following compulsory measures:
l
to connect in series an appropriate protection fuse to the selected output
l
to use through phase only or through neutral only for all the terminals
The connections for home-automation functions, or for operating as a roller-shutter or light control module,
depend on the operating mode selected during the programming phase.

The 4 terminals are all independent and can be controlled via the control panel.
They can be wired for any of the functions available to them.
