OARD INSTALLATION
The XPWR104HR power supply module is very easy to connect to your industrial or
automotive control system. Direct interface to PC/104 systems as well as EBX size
boards is achieved. This chapter tells you step-by-step how to install your XPWR104HR
into your system.
Board installation
Keep your board in its antistatic bag until you are ready to install it to your system!
When removing it from the bag, hold the board at the edges and do not touch the
components or connectors. Please handle the board in an antistatic environment
and use a grounded workbench for testing and handling of your hardware. Before
installing the board in your computer, check the power cabling. Failure to do so
may cause the power supply unit to malfunction or even cause permanent
damage.
General installation guidelines:
•
Touch the grounded metal housing of your computer to discharge any antistatic buildup and then remove the board
from its antistatic bag.
•
Hold the board by the edges and install it in an enclosure or place it on the table on an antistatic surface.
•
Install your board in your system, and wire the power supply correctly.
•
Failure to do so may cause the power supply unit to malfunction or even cause permanent damage to the device.
•
Make sure to use 16 AWG wire.
•
Twist power and ground wires to minimize input inductance
•
Keep input wires less than one foot in length
•
If you must use longer wires, you may want to attach a large value, high ESR capacitor to the input (i.e. 220uF 50V
electrolytic)
•
Check all wiring connections once and then once more again.
•
Check the input power to the board is in the range of 8 to 32V DC (36V maximum)
•
Do not hot plug the input or loads. This causes inductive spikes that can damage the board
•
Apply power to your XPWR104HR, and make sure the diagnostic LED’s indicate correct operation.
