Power connection
NOTE
• All system wiring and power connections must be made to ABYC
standards.
• The negative terminals of all batteries must be connected together.
• Refer to ABYC E-11 – AC and DC Electrical Systems on Boats
5.1.1 Planning your 12V power connections
Figure
shows a sample power schematic. For each actuator in your system, you
10
will need the following items (not included with your installation kit):
• A 12V DC power source capable of supplying 40A peak current during
aggressive use.
• A 60A circuit breaker, designed for marine use.
NOTE: Typical source connections
• Direct to the batteries.
• To battery switches. (Never switch the negative wire.)
• To a bus bar or power distribution panel. Ensure the wire size from the
bus to the batteries is sufficient to handle the peak current of all
devices connected to the bus.
• Red wire that meets ABYC requirements, of the appropriate size for the
intervening wire length between the actuator harness and the battery (see
figure
and table 2).

• Crimp lugs sized for connecting the circuit breaker to the power source.
• Secondary circuit protection devices if required (see note).
NOTE: Circuit protection
• ABYC standards require a circuit protection device within 7" (180 mm)
of the power source on all wires carrying positive voltage.
• If the circuit breaker is more than 7" (180 mm) from the source, a
secondary device (circuit breaker or fuse) must be located within 7"
of the battery to protect the intervening wire.
• Secondary device must be rated based on intervening wire size,
and usually has a higher rating than the circuit breaker.
• Refer to ABYC E-11 – AC and DC Electrical Systems on Boats for
more details.
