Low Current 12 VDC Power Connection Instructions
Reversing polarity on the DC power input to the Seakeeper can result in damaging the electronics in the control system.
- Install Seakeeper-provided Low Current DC Power Input Cable, (P/N 20248) to battery bank.
- Connect control power positive conductor (B+, red) through dedicated over-current protection device (customer supplied) and a dedicated Seakeeper isolation switch (customer supplied). A 2AWG, B+ conductor (red), is capable of carrying the current for both the High Current, Low Current, and Seawater Pump from the 12VDC power supply to the dedicated battery isolation switch.
- Connect negative conductor (B-, black) directly to battery minus terminal or negative DC bus bar.
- Before connecting Low Current Power Cable to Seakeeper, check for proper voltage and polarity with a DC multimeter using Figure 14 below.
When energizing DC power the first time, if display does not power up immediately then disconnect and inspect connector polarity.
- Connect low-current control power cable to Low Current 12 VDC power input connector on the Seakeeper, Deutsch DTP04-2P connector.
