For systems with art. UT2020/UT2010VC and power supply unit art. 1210/1210A, the maximum power
available for the outdoor entrance panel modules is 3.3 W.
Calculate the total power consumption of the modules in your system configuration using the Consumption
table.
If the total power consumption exceeds 3.3 W, connect a supplementary power supply unit (art. 1595) to
the V+ and V- contacts of the outdoor entrance panel, as shown in the figure below (see Connection with
separate power supply). In any case, the total absorption must be lower than 16.5 W.
