Seakeeper 18 Installation Manual (90672-3); S/N 18-254-2135 to Current

3.2 Electrical Equipment Power Connections

230 VAC Power Source Requirements

  1. 230 VAC (nominal), 1 Phase, 50/60 Hz, 30 A
  2. For installations of more than one Seakeeper, a separate circuit breaker must be used for each Seakeeper Motor Drive Box.

Drive Box AC Power Input Connection Instructions

  1. AC Power Input Cable: 3 x 10 AWG (3 x 6 mm2 CSA), 10 ft9 (3 m) length, Seakeeper supplied pre-installed.
    1. Locate AC power input cable on the Drive Box at the outboard cable gland.

Figure 29 – AC Power Input Cable wire
connections at AC Power Distribution Panel

2. Connect 230 VAC wires in AC Power Input Cable to a 30 A, double-pole Circuit Breaker at an AC
power distribution panel according to Figure 29 above.

24 VDC Power Source Requirements

  1. One 24 VDC, 10 A (Customer supplied) for Seakeeper Control Power, AND
  2. One 24 VDC, 10 A (20 A max)(Customer supplied) for DC Seawater Pump.
  3. A separate breaker should be used for each 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. 24 VDC, 10 A, 2 x 12 AWG (3 x 4.0 mm2 CSA) customer supplied.
    1. Install Seakeeper provided DC Power Input Cable, P/N 20248 (as shown in Drawing No. 90679).
      1. Route 24 VDC Power Cable to DC Power Distribution Panel.
      2. Terminate positive (B+, Red ) conductor to +24 VDC.
      3. Terminate negative (B-, Black) conductor directly to battery negative terminal.
    2. Before connecting cable to Seakeeper, check for proper voltage and polarity with a DC multimeter using Figure 30 below.
    3. Connect 24 VDC Input Cable to 24 VDC input receptacle on Seakeeper.

DC Seawater Pump 24 VDC Power Input Connection Instructions

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

  1. Install Seawater Pump Input Cable (P/N 20454) to Seakeeper 18 “SW Pump DC In” (as shown in Drawing No. 90679) with overcurrent protection corresponding to seawater pump selected.
  2. Connect the 14 AWG positive conductor (Red) through dedicated overcurrent protection device (customer supplied), maximum of 20 A, to dedicated battery isolation switch.
  3. Connect the 14 AWG negative conductor (Black) directly to battery negative terminal or DC main negative bus bar.
  4. Before connecting Seawater Pump Input Cable to Seakeeper, check for proper voltage and polarity with a DC multimeter using Figure 31 below.
Figure 31 – 24 VDC Seawater Pump Power Input
  1. Connect Seawater Pump Input Cable to Seawater Pump 24 VDC In connector on the Seakeeper, DEUTSCH DT04-2P connector.

DC Seawater Pump 24 VDC Power Output Connection Instructions

  1. Connect Seawater Pump Output Cable (P/N 20455) to the Seakeeper 18 wire harness connector labelled Seawater Pump Out.
    1. Seawater Pump Output Cable is a 2 x 14 AWG cable, 16 ft (5 m) length with a female Deutsch plug.
    2. Install Y-Branch SW Pump Output & Valve cable (P/N 20658) to end of “SW Pump 24VDC Out” cable as shown in top image of Figure 3324.
  2. Pumps rated at 24 VDC, 10 A maximum, customer-supplied, must be configured with a Deutsch DT series, 2-pin receptacle to mate with the connector shown in Figure 32.
Figure 32 – Seawater Pump Deutsch Connector
  1. The Seawater Pump Output Cable must be routed and installed in the vessel to the Y-Branch SW Pump Output & Valve Cable (P/N 20658) (socket end).
  2. Connect Y-branch cable plug end (socket end) to the customer-supplied receptacle end of the DC seawater pump cable. The recommended wiring is shown in Figure 33.
  3. Attach DTM-2S (socket end) into the male Deutsch DTM-2P connector of the 1 A inline fuse cable (P/N 20794). Connect the female connector of the inline fuse cable into the connector of the electric ball valve.
  4. Contact Seakeeper if desired to install customer-supplied relay on Seawater Pump Output Cable to power seawater pump and valve.
