24-V Voltage Supply
Setup Without Electrical Isolation
The most easiest connection method is the establishment of an electrical
isolation between the internal logic and the peripheral supply.
In this case, a power supply unit is appropriate to supply the IndraControl
L40. It is not permitted to use an autotransformer to ensure compliance
with overvoltage category II.
