DC Seawater Pump 12 VDC Power Input Connection Instructions
- 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).
- Connect the 16AWG plus 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.
- Connect the 16 AWG minus conductor (black) directly to battery minus terminal or DC main negative bus bar.
- Before connecting the SW Pump Power Input Cable to the Seakeeper 2, check for proper voltage and polarity with a DC multimeter using Figure 6 below.
- Connect SW Pump Power Input Cable to Seawater Pump 12 VDC In connector on the Seakeeper, DEUTSCH DT04-2P connector.

Seawater Pump 12 VDC Power Output Connection Instructions
- Locate the Seawater Pump Power Output Cable (P/N 20334) for “SW Pump 12VDC Out” connection on Seakeeper 2 wire harness (as shown in Drawing No. 90470).
- Pumps rated at 12 VDC, 15 amps maximum, customer-supplied, must be configured with a Deutsch DT series, 2-pin receptacle to mate with the connector as shown in Figure 7.
