High Current 12 VDC Power Connection Instructions

1. High Current 2 AWG conductors connect the Seakeeper to the DC source are supplied as length 13ft (4 m). Approximately 3 ft (1 m) is routed inside the Seakeeper frame.
   
   1. If installing cables NOT provided by Seakeeper, ensure the folowing:
      
      • Cable lengths do not exceed 29.5 ft (9 m)
      • Cable gauge is 2 AWG or larger
      • Cables bound together but not coiled
      • When connecting aftermarket cables to the Seakeeper motor drive, observe the following:
        
        • Ensure terminal stacks include flat washers, split-lock washers, and hex head screws that came with the Seakeeper.
        • Torque battery terminal screws to 97 in-lbs (11 Nm).
        • Verify lock washers seated flat and lugs cannot rotate (See Figure 12A).

2. Conductor length may be increased, but changing from 2 AWG to larger wire size does not allow longer length than 30 ft (9 m) each. The length limit is required to limit the inductance from the high current conductors.
3. Use the shortest length and most direct route to the battery bank as possible.
4. Bind positive (B+, red) & negative (B-, black) conductors together throughout entire length and do not coil.
5. Connect positive conductor (B+, red) through dedicated over-current protection device (customer supplied) and a dedicated isolation switch (customer supplied) then directly to battery positive terminal.
6. Connect negative conductor (B-, black) directly to battery negative terminal.

7. If the 2 AWG high current 12 V power input conductors are shortened or lengthened, use heavy-duty eyelet (closed end) terminal such as Molex 19221-0235 and follow instructions on Seakeeper Drawing No. 90470 – Seakeeper 2 Cable Block Diagram, sheet 2.
8. The bare wire strands should extend fully into the barrel of the heavy-duty eyelet and be crimped in two places if possible then sealed with double-wall heat shrink tubing. Crimp heavy-duty terminals with Quick Cable 4245 Crimp Tool, Molex 19284-0034 Crimp Tool, or equivalent using manufacturer’s instructions.
