Any clover or kettle lead will do. Cut the end off (not the one - that goes in the wall, but the kettle/clover connector). - Strip the protection away by a decent length, then strip the wires inside so that a decent amount of - copper is shown. Then wire up earth/live/neutral. This will vary according to what country you live in - and/or the colour codes that your cable uses inside. <b>Make sure to get this right, as a botched job - could result in extreme damage to you and your surroundings. Here's what mine looks like after wiring up - the power cable: <a href="images/x200/psu_power.jpg">images/x200/psu_power.jpg</a> - also, make sure - that the plug (for the wall) has the correct fuse. In my case I had a 240V wall socket, and the device - says that it accepts 1.5A at that voltage, so I used the smallest fuse available (3A). For 110-120V the device - says it needs 2.8A.</b> Also, if yours looks like in the image linked above, make sure to wrap electrical tape (lots) - around it for safety. (otherwise, don't touch the terminals while the PSU is plugged in). - </p> - <p> - Now take a red and black 20cm female-female jumper lead, and cut one of the ends off. Strip away the bare copper by about 1 or - 1.5cm so you get this: <a href="images/x200/stripped_jumper_lead.jpg">images/x200/stripped_jumper_lead.jpg</a>. - </p> - <p> - Black goes on -V, red goes on +V.

Then, - </p> - <p> - Then I twisted the exposed copper on the jumper leads (so that they don't fray), and wrapped each to one of the - screws each, around it near the head. I then screwed them in: - <a href="images/x200/psu_jumper_leads.jpg">images/x200/psu_jumper_leads.jpg</a>. - </p> - <p> - If you are using a different PSU, then the steps will change from those above. Anyway, once you are satisfied, - continue reading... - </p> - <h2>Setting up the BBB</h2> - <p> - Since it's a bare board (no case) and you are also touching inside your X200, you should be earthed/grounded. - <a href="images/x200/strap.jpg">images/x200/strap.jpg</a> shows how I earthed myself. This is to prevent you - from causing any ESD damage. The surface that you place components on should also be earthed/grounded. - (for this, I used a shielded ESD bag with a wire, copper exposed, attached from the bag to the exposed metal - part on a radiator, which was earthed - not professional, but it should work. see <a href="images/x200/mat.jpg">images/x200/mat.jpg</a>). - Most people ignore this advice and don't ground/earth themselves, at their own risk. You should also store the BBB - in a shielded anti-static bag when you are finished with it. - (the principles above apply to any computer components, since they are extremely sensitive te ESD). - </p> - <p> - These instructions may or may not work for you.
