Starting Up
Before connecting the switch to power and starting up, read and observe the instructions within this user guide
including Chapter 2/: General Safety Instructions.
The switch support three power supply options: DC terminal block, DC power Jack and PoE input with PD. When
multiple power sources are connected to the switch, the switch utilizes the power supply with the higher voltage or
the most stable power supply.
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.
Ensure easy access to the power cable. If the operating environment restricts power cable
access, guarantee disconnection using a separate cut-off fixture.
6.1.
Connecting to DC Terminal Block
To connect to an external 24 VDC to 48 VDC DC power supply and turn on and perform the following:
1.
Connect a ground wire to the ground connector.
2.
Insert the positive and negative wires of the external DC power supply to the DC-IN+/-contacts on the DC
terminal block and tighten the wire-clamp screw to prevent the wires from loosening.
3.
Turning on the external DC power supply automatically activates the switch.
When connecting the power follow the polarity indicated for DC-IN +/-.
The external DC power supply must be connected to a well-fused power supply.
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)
6.2.
Connecting to DC Power Jack
To connect the switch to an AC/DC power adapter with jack and turn on, perform the following:
1.
Connect a ground wire to the ground connector.
2.
Insert the AC/DC power adapter’s jack firmly into the DC-IN DC power Jack connector.
3.
Connecting the AD/DC power adapter to the mains power socket automatically activates the switch.
Do not use an extension cable to connect the switch.
