• Installation and maintenance must be performed only by qualified personnel.
• Disconnect the power supply before any maintenance operation and before accessing
the internal parts of the unit.
• Check the consumption of the loads driven by the outputs.
• Keep power cables separate from secondary circuits with safety extra low voltage (SELV).
• Warning: it may be necessary to supply the outputs with supporting
resistors to be able to lock the minimum value to 0V. Values to choose
according to the dimmer used.
TECHNICAL NOTES
CONNECTIONS
BUS
Use four-core signal cable (2x0.75 + 2x0.22) to connect the module to the RS485 serial port of the master
device (Wüdomo programmable thermostat). This cable must comply with CPR regulations while the minimum
recommended class is CcA-S3, Do, A3. To identify the current class of cables for different places of use, please
refer to the classification given in the CPR regulation. In the event of voltage drops along the 12V line
of the
BUS it is necessary to insert an additional power supply unit.
INPUTS/OUTPUTS
To connect inputs, it is sufficient to use a cable with a cross section of 0.5 mm
2
, while for the outputs a cable
suitable for the load must be used.
In the event of sections longer than 5m or in environments disturbed by electromagnetic fields, use a shielded
cable to connect the inputs. In this case, connect the shield to the GND terminal on the module side.
Do not exceed distances of 25 m between the dry control contact and the module input.
