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. Kontron assumes no responsibility for any damage resulting from
failure to comply with these requirements.
Only connect the switch to an external power supply providing the voltage type (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, first connect the ground cable to the ground stud 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.
When connecting the power follow the indicated polarity P1+/- and P2+/-.
To protect the switch and any connected devices, 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, 5.08 mm (0.2 inch)
•
Wire strip length 7 mm (0.28 inch)
•
Wire size range: Solid wire: 12~24 AWG and Stranded wire: 12~24 AWG
•
Wire length 3 m (9.84 ft.) maximum
With multiple power sources connected to the switch, the switch utilizes the power supply
with the higher voltage or the most stable power supply.
To connect the switch to an external DC power supply and start up, perform the following:
1.
Turn off the external DC power supplies via a disconnecting device (fuse/circuit breaker), to ensure that no
power flows during the connection procedure.
2.
Connect the ground stud to an appropriate earth connection.
3.
Insert the positive and negative wires of the first external DC power supply to the P1+/–, contacts on the DC
terminal block and tighten the wire-clamp screws to prevent the wires from loosening.
4.
Insert the positive and negative wires of the second external power supply to the P2+/- contacts on the DC
terminal block and tighten the wire-clamp screws to prevent the wires from loosening.
5.
Insert the DC terminal block into the switch’s power connector.
6.
Turning-on the external DC power supplies automatically activates the switch.
