Seakeeper 3 Installation Manual (90378-6); S/N 3-223-3836 to 3-231-4222
6.0 Installation & Start Up Checklist
6.1 Installation & Start Up Introduction
Reference Documents:
The Installation and Start Up Checklists in this section provide an overview of the primary steps covered in the installation manual and should be referenced throughout the installation process. Upon completion of the
Seakeeper 3 installation, the installer should commission each Seakeeper unit with the Seakeeper Commissioning Form (90437). The Commissioning Checklist Work Instruction (SWI-105) provides a checklist of items to inspect and verify during the commissioning process and serves as a supplement to the Seakeeper Commissioning Form (90437).
All Seakeeper stabilizers should be commissioned to verify installation specifications and requirements have been implemented properly. The commissioning process should include completion of the Seakeeper
Commissioning Form (90437), all the items in the Installation Checklist, and verification of Seakeeper 3 operation without alarms or abnormal behavior.
6.2 Installation Checklist
6.2.1 Mechanical Checklist

6.2.2 Electrical Checklist
6.2.2.1 High Current 12 VDC Power Source, Cable 1 & 2
| CHECK | REQUIREMENT TO BE MET |
| Connect cable 1 and 2 to customer supplied 2 AWG B+ and B- conductors to allow for routing to 12 VDC power source. * Connect Cable 1, B+ conductor (red) through 100 A circuit breaker(customer-supplied) and a dedicated battery isolation switch (customer-supplied), directly to the battery positive terminal or bus bar. * Connect Cable 2, B- conductor (black), to battery negative terminal or DC negative bus bar. | |
| If the 2 AWG high-current 12V power input conductors are shortened or lengthened, use heavy-duty eyelet (closed end) terminals such as Molex19221-0235. |
6.2.2.2 Low Current 12 VDC Power Source, Cable 7
| CHECK | REQUIREMENT TO BE MET |
| Connect Cable 7 positive (red) directly to a customer-supplied 15 A circuit breaker, then to the dedicated battery isolation switch | |
| Connect Cable 7 negative (black) to the DC negative bus bar or battery negative terminal. | |
| Plug Cable 7 connector end into the DT-Series connector labelled Low-Current 12 VDC in connector on the Seakeeper wire harness. |
6.2.2.3 Seawater Pump Connection, Cable 8 & 5
| CHECK | REQUIREMENT TO BE MET |
| Connect Cable 8 positive (red) directly to a customer-supplied circuit breaker corresponding to the seawater pump overcurrent protection rating (max 15 A), then to the dedicated battery isolation switch. | |
| Connect Cable 8 negative (black) to the DC main negative bus bar or battery negative terminal. | |
| Connect Cable 5 receptacle end (pins) to Seakeeper SW Pump 12 VDC Out and the plug end (sockets) to customer-supplied 12 VDC seawater pump cable Deutsch connector termination. |
6.2.2.4 Ground Connection, Cable 6
| CHECK | REQUIREMENT TO BE MET |
| Install lugs on both ends of customer-supplied 4 AWG ground cable. | |
| Connect one end of Cable 6 to nearest vessel ground and other end to ground stud on Seakeeper frame. | |
| 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. |
6.2.3 Cooling Checklist
| CHECK | REQUIREMENT TO BE MET |
| Purchase seawater pump for Seakeeper 3 to provide 2 – 4 GPM (7.6 – 15.1LPM) with a max overcurrent protection rating of 15 A. Optional seawater pump can be purchased through Seakeeper, P/N 30331. | |
| Connect and route 3/4″ (19 mm) seawater inlet hose from seacock valve to the seawater strainer, seawater pump, and then to the Seakeeper 3 heat exchanger inlet. | |
| Connect and route 3/4″ (19 mm) seawater outlet hose from Seakeeper 3 heat exchanger outlet to the seawater overboard. | |
| Test seawater pump: * Verify 2 GPM (7.6 LPM) minimum and 4 GPM (15.1 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. |
6.3 Start-Up Checklist
Refer to Seakeeper 3 Operation Manual, Startup Section for detailed start-up instructions.
Prior to beginning the start-up sequence all previous Sections of the Installation Manual for Mechanical, Electrical, and Cooling installation must be complete. Before continuing, the Seakeeper 3 cover must be installed, and the operating clearances must be clear of personnel and equipment
| CHECK | REQUIREMENT TO BE MET |
| Remove lifting eyebolts and install sealing bolts and washers into lifting eyeholes and install cover. | |
| Energize battery isolation switch, high-current 110 A breaker, low-current 15 A breaker, and seawater pump breaker. | |
| Verify Seakeeper display is active and no alarms present. * If the Seakeeper 3 display does not activate, turn off all circuit breakers immediately and check all wiring connections. | |
| Check that battery voltage exceeds 12 VDC. A minimum battery voltage of11.2 VDC is required for the duration of Seakeeper spool-up. | |
| Override seawater pump “ON” (at 0 RPM hold down SERVICE button (wrench icon) for 5 seconds) and verify flow at seawater outlet. | |
| Press Seakeeper ON/OFF Button and follow instructions in Seakeeper 3 Operation Manual, Section 2 for complete start-up instructions. | |
| Verify no alarms are present. | |
| Power Seakeeper 3 down, the Seakeeper 3 flywheel will take 2+ hours to coast down to 0 RPM. |
