High Current 12 VDC Power Source: Cable 1 & 2

Butt splice Cable 1 and Cable 2 to customer-supplied 2 AWG B+ and B- conductors to allow for routing to 12 VDC power source.
- Butt splice instructions can be found in Drawing No. 90511 – Seakeeper 1 Cable Block Diagram.

Heat shrink
Connect spliced Cable 1, B+ conductor (red), through 80 A circuit breaker (customer-supplied) and a dedicated battery isolation switch (customer-supplied), directly to the battery plus terminal or bus bar.
Connect spliced Cable 2, B- conductor (black), to battery minus terminal or DC main negative bus bar.

Seawater Pump Connection: Cable 5 & 7

Connect Cable 7 positive (red) directly to a customer-supplied circuit breaker corresponding to the seawater pump current overprotection rating (max 15 A), then to the dedicated battery isolation switch.
Connect Cable 7 negative (black) to the DC main negative bus bar or battery minus terminal.
Connect Cable 5 receptacle end (pins) to Seakeeper 1 SW Pump 12 VDC Out and the plug end (sockets) to customer-supplied 12 VDC seawater pump cable Deutsch connector termination.

Ground Connection: Cable 6

Butt splice Cable 6 to customer-supplied ground wire, 4 AWG, with sufficient length to reach the vessel ground.
Vessel grounding bus to comply with:
- EM/IEC 60204-1 Clauses 6.3.3 and 8.2.3.
- ABYC E-11 July 2018 Clauses 11.5.2 and 11.16.1.

Seakeeper Display Connection

Ensure one of the following display options is installed, refer to TB 90573 – Seakeeper 1 Display Options for a detailed description:
- Option 1: Compatible Multifunction Display (MFD), refer to Seakeeper MFD Compatibility Technical Bulletins.
- Option 2: Seakeeper 5” Touch Display, P/N 90600.
Option1: Connect Seakeeper Compatible MFD
- Purchase custom Seakeeper MFD integration cable based on the compatible MFD onboard.
- Connect Cable 10 to ethernet connection of Seakeeper ConnectBox.
- Connect 4 pin end of MFD integration cable to male end of Cable 10 and Ethernet M12 end of MFD network port or vessel network hub.
Option 2: Seakeeper 5” Touch Display, P/N 90600
- Purchase Seakeeper 5” Touch Display (P/N 90600).
- Install Seakeeper 5” Touch Display on or near the helm station.
- Connect Cable 3 (included with P/N 90600) from Seakeeper 1 wire harness and route to Seakeeper 5” Touch Display.

NMEA 2000 Network Connection

Purchase seawater pump for Seakeeper 1 to provide 2 – 4 GPM (7.6 – 15.2 LPM) with a max overcurrent protection rating of 15 A.
- Optional seawater pump can be purchased through Seakeeper, P/N 30331.

Connect and route seawater inlet hoses from seacock valve to the seawater strainer, seawater pump, then Seakeeper 1 heat exchanger.
Connect and route seawater outlet hoses from Seakeeper 1 heat exchanger to the seawater overboard.
Test seawater pump.
- Verify 2 GPM (7.6 LPM) minimum and 4 GPM (15.2 LPM) maximum seawater flow through heat exchanger under all operating conditions of the vessel.
Verify coolant level in heat exchanger coolant reservoir, fill if needed.
