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.
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.
To connect the switch to an external DC power supply and turn on, perform the following:
1.
Connect a ground wire to the ground stub
2.
Insert the positive and negative wires of the first external DC power supply to the PWR1+/–, contacts on the DC
terminal block and tighten the wire-clamp screw to prevent the wires from loosening.
3.
Connect the second external power supply to the PWR2+/- contacts.
4.
Turning on the power supply automatically activates the switch.
When connecting the power follow the indicated polarity PWR1+/- and PWR2+/-.
When attaching power wires to the DC terminal block’s power contacts consider:
•
DC terminal block pitch, 5.08 mm
•
Wire size range: Solid wire: 12~24 AWG and Stranded wire: 12~24 AWG
•
Wire length 3 m (9.84 ft.) maximum
•
Wire strip length 7 mm (0.28 in)
With multiple power sources connected to the switch, the switch utilizes the power supply
with the higher voltage or the most stable power supply.
