CarNetix PSU-PC19 V2.0 Installation Manual2.3 Connecting the WiringAfter you have set the jumpers for the options and performance of the PSU-PC19 you can connectthe input and output wiring. The steps outline below should be followed to insure proper operationof the PSU-PC19 and Xenarc SC8.Step 1 – Connect the input power and ignition to the PSU-PC19.Use heavy gauge wire directly connected to the battery (via 15A fuse and distribution block).4-8 GA wire is recommended if the SC8 runs a 2-3GHz processor. 8-10 GA wire isrecommended for lower speed processors. Using wire that is too small will cause the SC8 tonot survive engine cranking. Connect the battery wire to BOTH red input wires on J1 (pins 3& 6).Step 2 – Connect Ground to the PSU-PC19.We recommend that you either run another wire directly to the battery, or connect directly tothe car chassis for grounding the PSU-PC19. If you run a wire to the battery, make sure it isthat same size as your +12V battery wire used in step 1. If you run a ground wire to the car’schassis, make sure to find a secure ground that is not corroded or painted and use the samesize wire as your +12V battery wire used in step 1.Step 3 – Install optional Valet Switch.A simple SPST switch installed in series with the ignition wire will allow you to manuallydisable the PSU-PC19 so that it does not come on when the ignition is turned on. This isoptional and for convenience only- 15 - |
