Continuous Current | 75 A |
Overcurrent Protection | 100 A (Customer Supplied) |
High Current 12 VDC Power Connection Instructions
- 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.
- 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.
- Use the shortest length and most direct route to the battery bank as possible.
- Bind plus (B+, red) & minus (B-, black) conductors together throughout entire length and do not coil.
- Connect plus conductor (B+, red) through dedicated over-current protection device (customer supplied) and a dedicated isolation switch (customer supplied) then directly to battery plus terminal.
- Connect minus conductor (B-, black) directly to battery minus terminal.

- 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.
- 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.
