Power Specification
The switch supports power supplied from a DC terminal block, DC Power Jack or Poe PD Input. The power supplied
used must be able to supply the connected PDs with adequate power. The external power source used must fulfill the
specified electrical ratings in this user guide and on the switch’s type label, and comply with the safety requirements
of UL/IEC 62368-1.

Protection
Reverse power protection
Only connect the switch to an external power supply providing the voltage type (AC or DC)
and the input power (max. current) specified on the Kontron Product Label and meeting the
requirements of the Limited Power Source (LPS) and Power Source (PS2) of UL/IEC 62368-1 .
Before connecting to power connect the ground cable to the ground connector and ensure
that the installation sites ground meets the grounding requirements specified in your local,
national and international region.
The DC power supply must be connected to a well-fused power source.
Input power should be within the range of 48 VDC to 56 VDC for PoE compliance and
42.5 VDC to 57 VDC for PoE+/PoE++ compliance.
To protect the switch and any connected peripherals, a sufficient dimensioning of the power
cable wires must be selected – according to the maximum electrical specifications on the
product label – as stipulated by EN62368-1.
When attaching power wires to the DC terminal block’s power contacts consider:
•
DC terminal block pitch, 3.81 mm
•
Wire size range: Solid wire: 16~28 AWG and Stranded wire: 16~28 AWG
•
Wire length 3 m (9.84 ft.) maximum
•
Wire strip length 7 mm (0.28 in)
