2.2.1 HIGH CURRENT 12 VDC POWER SOURCE REQUIREMENTS:
1. Source: Battery Bank, 12 VDC, Marine, Deep Cycle
2. Voltage Range: 11.3 – 16 VDC
3. Continuous Current: 55 A
4. Overcurrent Protection: 80 A (Customer-Supplied)
2.2.2 HIGH CURRENT 12 VDC POWER CONNECTION INSTRUCTIONS
1. CABLE 1 and CABLE 2, 2AWG conductors, connect to the high current DC input power are
supplied as length 0.35m. Approximately 0.1m is routed within the gyro frame.
2. Customer-supplied 2AWG cables must be spliced in series in accordance with the Crimping
Instructions in Drawing No. 90511, using Seakeeper-supplied butt connectors, to increase to
desired length. The maximum cable length is 9.0 m each.
a. The Crimping Instructions per Drawing No. 90511 are shown in the following figure.
3. Crimp CABLE 1 to B+ Conductor (red). Conductor should be continuous throughout entire
length; do not coil. The most direct route to the 12VDC Power source should be used.
a. Repeat Step 3 for CABLE 2 to B- Conductor (black).
b. Install approximately 2” (51 mm) of double wall (adhesive lined) heat shrink tubing over
entire butt connector and onto both sides of conductor insulation.
4. Connect plus conductor (B+, Red) through dedicated 80A overcurrent protection devic
e
(
customer-supplied) and a dedicated isolation switch (customer-supplied), then directly to
battery plus terminal or bus bar.
5. Connect minus conductor (B-, Black) directly to battery minus terminal or DC negative bus.
