ATTENTION
Hazard due to overvoltage
If the protective earth is not attached, there is a
danger of overvoltage at the device.
Always attach the protective earth!
The power supply is realized by means of a transformer. The primary side of the transformer, which is
connected to mains, is electrically insulated from the secondary side of the transformer, which provides
the internal power supply.
Functional EMC protection is provided only if the PE-pin of the power supply is connected to earth.
When mounting on mobile vehicles, a functional earth must be established for this purpose.
* The UL marking only applies to 24 VDC power supply.
