3.2 Electrical Equipment Power Connections

AC Input Power Source Requirements

1. Either of two AC input voltages are acceptable:
   
   1. 110 – 120 VAC (nominal) (+/- 10%), 1 Phase, 50/60 Hz, 30 A
   2. 208 – 230 VAC (nominal) (+/- 10%), 1 Phase, 50/60 Hz, 20 A
2. A separate circuit breaker should be used for each Seakeeper Drive Box in multiple Seakeeper installations.

Seakeeper DC Control Power Connection Instructions

1. 12 VDC, 15 A, 2 x 12 AWG (3 x 4 mm² CSA) customer supplied.
   
   1. Install Seakeeper provided DC Power Input Cable, P/N 20248 (shown in Drawing No.90396):
      
      1. Route DC Power Input Cable to DC Power Distribution Panel.
      2. Terminate positive (B+, Red) conductor through dedicated over-current protection device (customer supplied) and a dedicated Seakeeper isolation switch (customer supplied) then directly to battery plus terminal.
      3. Terminate negative (B-, Black) conductor directly to battery negative terminal or negative bus.
   2. Before connecting DC Power Input Cable to Seakeeper, check for proper voltage and polarity with a DC multimeter using Figure 33.
   3. Connect DC Power Input Cable to 12 VDC input receptacle on Seakeeper.

DC Seawater Pump 12 VDC Power Input Connection Instructions

1. Install DC SW Pump Input Power Cable (P/N: 30327) to Seakeeper 6 “SW Pump DC In” (shown in Drawing No. 90396) with overcurrent protection corresponding to seawater pump selected.
2. Connect the 16 AWG positive conductor (red) through dedicated overcurrent protection device (customer-supplied), maximum of 15 A, to dedicated battery isolation switch.
   
   • 24 VDC, 10 A max can be used for Seawater Pump power.
3. Connect the 16 AWG negative conductor (black) directly to battery negative terminal or DC main negative bus bar.
4. Before connecting DC SW Pump Input Power Cable to Seakeeper, check for proper voltage and polarity with a DC multimeter using Figure 34.

5. Connect DC SW Pump Power Input Cable to Seawater Pump 12 VDC In connector on the Seakeeper, DEUTSCH DT04-2P connector.

DC Seawater Pump 12 VDC Power Output Connection Instructions

1. Connect DC SW Pump Power Output Cable (P/N 20334) to the Seakeeper 6 wire harness connector “SW Pump 12VDC Out” for DC power output to the seawater pump.
   
   1. Seawater Pump Output Power Cable is a 2 x 16AWG cable, 16 ft (5 m) length, with a size 16 female Deutsch plug.
2. Pumps rated at 12 VDC, 15 A maximum (24 VDC, 10 A), customer-supplied, must be configured with a Deutsch DT series, 2-pin receptacle to mate with the connector shown in Figure 35.

3. The DC SW Pump Power Output Cable must be routed and installed in the vessel from the Seakeeper 6 “SW Pump 12VDC 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). The recommended wiring is shown in Figure 36.
5. Connect Y-branch cable DTM-2S connector to DTM-2P connector of fused cable (P/N 20794) and the electric valve.
6. Contact Seakeeper if desired to install customer-supplied relay on DC SW Pump Power Output Cable to power Seawater Pump and valve.
