Note before connecting the device
Warning
The device may only be connected to 24 VDC power supply systems which meet
the requirements of a safe extra-low voltage with protective separation (SELV); a
protective conductor must also be connected. The conductors must be able to
withstand the short-circuit current of the 24 VDC power supply, so that a short cir-
cuit will not damage the cable. Only cables with a cross-section between a mini-
mum of 0.25 mm
connected.
Notice
The 24 VDC power supply must match the input specification of the device
Technical data (Chapter 13).
Caution
Ensure that the functional grounding is connected correctly.
It is essential to ensure the correct polarity with direct current.
Functional check
After switching on, the POWER LED must light up green.
