21. Connect the new filament board and wires to the source interface board. Make sure to
bend the wires so that there is no strain on the filament and so that the wires do not come
into any contact with metal surfaces, including the front door or magnet yoke when the
door is closed.
CAUTION Although the wires are insulated with glass braid, they may short through the
insulation if they touch a metal surface. Use caution when closing the door to ensure the
magnets to not come in contact with the source block or top of the filament. This might
cause them to be disengaged from the holder.
ATTENTION Bien que les fils soient isolés à l'aide de fibre de verre, ils peuvent
court-circuiter à travers l'isolation s'ils entrent en contact avec une surface métallique. Soyez
prudent lorsque vous fermez la porte, afin de vous assurer que les aimants n'entrent pas en
contact avec le bloc source ou le dessus du filament. Cela peut les désengager du support.
