DC Seawater Pump 12 VDC Power Input Connection Instructions

  1. Located the Seawater Pump Power Input Cable (P/N 30327) for Seakeeper 2 “SW Pump DC In” connection on Seakeeper 2 wire harness (as shown in Drawing No. 90470).
  2. Connect the 16 AWG positive conductor (red) through dedicated overcurrent protection device (customer-supplied), maximum of 15A, to dedicated battery isolation switch.
    • The High Current, 2AWG B+ conductor (red), is capable of carrying the current for both the High Current, Low Current, and Seawater Pump from the 12VDC power supply to the dedicated battery isolation switch.
  3. Connect the 16 AWG negative conductor (black) directly to battery negative terminal or DC main negative bus bar.
  4. Before connecting the SW Pump Power Input Cable to the Seakeeper 2, check for proper voltage and polarity with a DC multimeter using Figure 15 below.
  5. Connect SW Pump Power Input Cable to Seawater Pump 12 VDC In connector on the Seakeeper, DEUTSCH DT04-2P connector.
