DC Seawater Pump and Valve 24 VDC Power Output Connection Instructions

1. Connect Seawater Pump Output Cable to the Seakeeper 9 “SW Pump 24VDC Out” for DC power to the seawater pump.
   
   1. Install Y-Branch SW Pump Output & Valve cable (P/N 20742) to end of “SW Pump 24VDC Out” cable as shown in top image of Figure 34.
   2. Seawater Pump Output Cable is a 2 x 16 AWG cable, 16 ft (5m) length with a size 16 female Deutsch plug.
2. Pumps rated at 24 VDC, 10 A maximum, customer-supplied, must be configured with a Deutsch DT series, 2-pin (male) receptacle to mate with the connector shown in Figure 33.

3. Seawater Pump Output Cable must be routed and installed in the vessel from the Seakeeper 9 “SW Pump 24VDC Out” Deutsch connector (pins end) to the Y-Branch SW Pump Output & Valve Cable
   (P/N 20742) (socket end).
4. Connect Y-branch cable plug end (socket end) to the customer-supplied receptacle end (pins end) of seawater pump. The recommended wiring is shown in Figure 34.
5. Connect Y-branch cable DTM-2S of cable to DTM-2P connector of inline 1 A fuse cable (P/N 20794) and the electric valve.
6. Contact Seakeeper if desired to install customer-supplied relay on Seawater Pump Output Cable to power seawater pump and valve.
