To remove the cover from the Power Distribution Module (ELK-PD9), use a small object like a screw driver to press into the slots located on the end of the cover. Using Table 1 or Table 2 below, select an AC or DC Power Source that provides enough current to power the number of devices to be used. The Power Source voltage must also match the device's voltage requirements. Mount the Power Distribution Module near the Power Source that will be used to power the devices. Connect the Power Source to the Power Distribution Module via the two Input Power Screw Terminals or the 2. 1mm DC jack(J1) located to the right of the terminals. Connect a two conductor cable from the Power Distribution Module's Output terminals to the devices to be powered. If desired, the total current draw can be measured at the Master Power Switch using an Ammeter while the switch is off. Replace the plastic cover on the Power Distribution Module. Table 1: Sizing the Power Supply Table 2: Quick Power Supply Selection by Number of Devices Calculate the total combined power consumption of Select a column that closely approximates the power consumption of each device. Select a Power Supply which has a desired voltage, select the row that meets or exceeds the number of desired devices. Available Power capacity that meets or exceeds appropriate Power Supply Model # is shown at left. [. . . ] THE SIZE OF THE INPUT POWER SOURCE MUST BE LARGER THAN THE COMBINED TOTAL LOAD OF THE ATTACHED DEVICES. THE INPUT POWER SOURCE MUST ALSO MATCH THE DEVICE'S OPERATING VOLTAGE SPECIFICATIONS OPTIONAL: 12 VOLT DC PLUG-IN POWER SUPPLY NEG POS SW1 POWER DISTRIBUTION 9 OUTPUTS [. . . ]
