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

Reversing polarity on the DC power input to the Seakeeper can result in damaging the electronics in the control system.

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.

When energizing DC power the first time, if Display does not power up immediately then disconnect and inspect connector polarity.

3.2.5 DC Seawater Pump 12 VDC Power Input Connection Instructions

Connecting the DC Seawater pump in any other manner than recommended by Seakeeper may cause internal failure.

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.

3.3 Electrical Equipment Ground Connections

Seakeeper to Vessel Ground Connection Instructions

1. Connect the Seakeeper foundation ground to vessel ground as shown in Figure 7.
2. Install Cable 6 (4 AWG or 22.0 mm², Customer supplied) from the M6 brass ground stud on the Seakeeper rear brace to a suitable vessel ground.
   • EN/IEC 90204-1 Clauses 6.3.3 and 8.2.3
   • ABYC E-11 July 2018 Clauses 11.5.2 and 11.16.1.

NOTE: USE ONLY THIS LOCATION FOR GROUNDING THE SEAKEEPER TO THE VESSEL GROUND.

3. Ground connection should be made with vessel bonding system, if available. However, the ground is not
referring specifically to a bonding system but for outboard boats generally refers to the outboard engine
negative terminal. Per ABYC E-11 (2018), Clause 11.5.2.7.4: If the negative side of the DC system is to be
connected to the ground, the connection shall be made only from the engine negative terminal, or its bus, to
the DC grounding bus. This connection shall be used only as a means of maintaining the negative side of the
circuit at ground potential and is not to carry current under normal operating conditions.

4. A proper ground connection is critically important for corrosion protection and helps to ensure the
ignition protection of the unit by ensuring it does not carry any stray current.

3.4 Electrical Equipment Mounting

Precautions: Each item of electrical equipment has specific mounting instructions. These instructions
should be followed to ensure proper function of the Seakeeper.

Do NOT move Seakeeper mounted components from their
locations or incorrect Seakeeper operation will result.
