Info

Power is run to a printed circuit card mounted on the right wall of the enclosurewith screws and nuts. The charger is wired in parallel with the battery so that itcan provide charging power to the battery as well as power the unit when it isplugged in. The battery the takes over once wall power is disconnected. InFigure 2.3.20, the white wires are running from the charger whilst the red andyellow immediately to their right run from the battery.Figure 2.3.20: Power Distribution Circuit CardThe other wires visible run to the various other components. A 5 volt limiterprovides 5 volts to those components which require less power.Next to the charger and mounted to the enclosures right wall is the fan. The fanis strategically placed to provide the most airflow over the charger, which is byfar the hottest component. The driver, another hot component, is placed nextto the air intake to facilitate its cooling.The battery is a 12 volt lead-acid battery. It is secured into the front left corner ofthe enclosure by brackets, which are mounted to the enclosure themselves. Thebattery itself is not secured to facilitate easy removal and replacement.91
