Connecting as power supply:
The LCN-NH24 can also be used as a simple power supply,
as query voltage for a sensor module (LCN-BU4L) .
The power supply offers an electrical isolation from the
query voltage to the mains power.
The power supply is connected primary side on the R2
(phase) and to the N terminal. On the secondary side, the
blue terminal (see illustr. on the right) is connected to the
M terminal of the LCN-BU4L. The orange terminal then
branches off to the single push-buttons/switches.
