Printed Circuit Board
Replacement

The replacement of printed circuit boards should be handled in a careful manner.

There are no direct screw/terminal connections on any of the Low Voltage circuit
boards. All wire/terminal connections are made with plugs that plug into the
circuit boards. This means that changing boards only requires the removal of the
plugs, minimizing the chance of mistakes when reconnecting all of the wiring.
