3.2 Electrical Equipment Power Connections

3.2.1 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.

3.2.2 Drive Box AC Power Input Connection Instructions

1. Cable: 3 x 10 AWG (3 x 6mm² CSA), 10 ft (3 m) length, Seakeeper supplied pre-installed.
   
   1. Locate Cable 2 for AC power input to the Drive Box at the outward of two cable glands.
      
      

3.2.3 Low Current 12 V Power Input

1. One 12 VDC, 15 A (Customer supplied) for Seakeeper Control Power, AND
2. One 12 VDC, 15 A OR 24 VDC, 10 A (Customer supplied) for DC Seawater Pump.
3. A dedicated breaker should be used for Seakeeper control and Seawater Pump power for each Seakeeper unit.

3.2.4 Seakeeper DC 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 as Cable 1 (as shown in Drawing No.90396).
      
      1. Route Cable 1 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 Cable 1 to Seakeeper, check for proper voltage and polarity with a DC multimeter using Figure 3 below.
   3. Connect Cable 1 to 12 VDC input receptacle on Seakeeper.

3.2.5 DC Seawater Pump 12 VDC Power Input Connection Instructions

1. Install Cable 8 (P/N: 30327) to Seakeeper 6 “SW Pump DC In” (as shown in Drawing No. 90396) with overcurrent protection corresponding to seawater pump selected.
2. Connect the 16 AWG plus 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 minus conductor (black) directly to battery minus terminal or DC main negative bus bar.
4. Before connecting Cable 8 to Seakeeper, check for proper voltage and polarity with a DC multimeter using Figure 4 below.

5. Connect Cable 8 to Seawater Pump 12 VDC In connector on the Seakeeper, DEUTSCH DT04-2P connector.

3.2.6 DC Seawater Pump 12 VDC Power Output Connection Instructions

1. Connect Cable 5 (P/N 20334) to the Seakeeper 6 “SW Pump 12VDC Out” for DC power output to the seawater pump.
   
   1. Cable 5 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 5.

3. Cable 5 must be routed and installed in the vessel from the Seakeeper 6 “SW Pump 12VDC Out” Deutsch connector (pins end) to the DC seawater pump cable Deutsch connector (socket end).
4. Connect Cable 5 plug end (socket end) to the customer-supplied receptacle end (pins end). The recommended wiring is shown in Figure 6.
5. Contact Seakeeper if desired to install customer-supplied relay on Cable 5 to power Seawater Pump.
