High Current 12 VDC Power Connection Instructions<\/h3>\n\n\n\n
    \n
  1. Connect positive and negative High-Current 12 VDC cables, 2 AWG (33.6 mm2<\/sup>) conductors, to the 12 VDC power source.
    \n
      \n
    1. The positive and negative cables are supplied with a length of 1.8 m, and approximately 0.5 m is routed within the gyro frame (1.3 m outside frame).<\/li>\n<\/ol>\n<\/li>\n\n\n\n
    2. Splice customer-supplied 2 AWG conductors to the positive and negative 2 AWG cables per the Crimping Instructions of Figure 4, using Seakeeper<\/span><\/span>-supplied butt connectors, to increase conductors to the desired length. The maximum cable length is 29.53 ft (9.0 m) each<\/strong>. See also Figure 4 below for splicing.<\/li>\n\n\n\n
    3. Crimp the positive High-Current Cable to B+ Conductor (red). Conductor should be continuous throughout entire length; do not coil. The most direct route to the 12 VDC power source should be used.
      \n
        \n
      1. Repeat Step 3 for the negative High-Current Cable to B- Conductor (black).<\/li>\n\n\n\n
      2. Install approximately 2 in. (51 mm) of double wall (adhesive lined) heat shrink tubing over entire butt connector and onto both sides of conductor insulation.<\/li>\n<\/ol>\n<\/li>\n\n\n\n
      3. Connect positive conductor (B+, red) through dedicated 80 A overcurrent protection device (customer-supplied) and a dedicated isolation switch (customer-supplied), then directly to battery plus terminal or bus bar.<\/li>\n\n\n\n
      4. Connect negative conductor (B-, black) directly to battery minus terminal or DC negative bus.<\/li>\n<\/ol>\n\n\n

        1. Connect Seawater Pump Input Cable (P\/N: 30327) to Seakeeper<\/span><\/span> 1 \u201cSW Pump DC In\u201d as shown in Drawing No. 90511 \u2013 Seakeeper<\/span><\/span> 1 Cable Block Diagram<\/em>, with overcurrent protection corresponding to seawater pump selected.<\/li>\n\n\n\n
        2. Connect the 16 AWG (1.5 mm2<\/sup>) plus conductor (red) through dedicated overcurrent protection device (customer-supplied), maximum of 15 A, to dedicated battery isolation switch.
          \n
            \n
          1. The positive High-Current 12 VDC cable, 2 AWG B+ conductor (red), is capable of carrying the current for both the High Current and Seawater Pump from the 12 VDC power supply to the battery isolation switch. <\/li>\n<\/ol>\n<\/li>\n\n\n\n
          2. Connect the 16 AWG (1.5 mm2<\/sup>) minus conductor (black) directly to battery minus terminal or DC main negative bus.<\/li>\n<\/ol>\n\n\n

            1. Connect Seawater Pump Output Cable to the Seakeeper<\/span><\/span> 1 \u201cSW Pump 12 VDC Out\u201d for DC power output to the seawater pump. The cable is a 2 x 16 AWG cable (1.5 mm2<\/sup>), 16 ft (5 m) length, with a size 16 female Deutsch plug.<\/li>\n\n\n\n
            2. Pumps rated at 12 VDC, 15 A maximum, customer-supplied, must be configured with a Deutsch DT series, 2-pin receptacle to mate with the connector shown in figure 6.<\/li>\n<\/ol>\n\n\n
