• Connect metallic housings or enclosures of installed electrical appliances to the
protective conductor system in the craft (green or green with a yellow stripe
conductor).
• Use double insulated or grounded (earthed) electrical appliances.
• If the reverse polarity indicator is activated, do not use the electrical system. Correct
the polarity fault before activating the electrical system on the craft.
WARNING: Do not work on an energized AC system.
WARNING: To minimize shock and fire hazards:
• turn off craft’s shore-power connection switch before connecting or disconnecting
shore-power cable;
• connect shore-power cable to craft’s inlet before connecting to shore-power
source;
• disconnect shore-power cable at shore-power source first;
• if reverse polarity indicator is activated, disconnect cable immediately;
• close shore-power inlet cover tightly when not in use;
• do not alter shore-power cable connectors, use only compatible connectors.
DC Electrical System 4-4
Please refer to the Electrical One Line diagram (EL–04-04), the Electrical Power Flow
diagrams (EL-04-14), and the 12Volt Supply Distribution diagram (EL-04-03) for detailed
description of the DC electrical system.
The 12-volt DC system is controlled by circuit breakers on the main electrical panel. The two
engine start batteries are located in their respective engine compartments with local
switches under the steps in each hull. The generator set has a dedicated start battery
located in the forward starboard locker. The ship’s service batteries are four 6-volt deep-
cycle batteries connected in series/parallel, located in the forward mast base locker with a
switch under the navigation table in the saloon.
WARNING - NEVER:
• work on the electrical installation while the system is energized;
• modify the craft’s electrical system or relevant drawings: installation,
alterations and maintenance should be performed by a competent marine
electrical technician;
• alter or modify the rated current amperage or overcurrent protective devices;
• install or replace electrical appliances or devices with components exceeding
the rated current amperage of the circuit;
• leave the craft unattended with electrical system energized, except automatic
bilge-pump, fire protection and alarm circuits.
WARNING: Safety precautions should be observed when working around batteries
because of the presence of acid and hydrogen
Voltage and current meters are provided, with a selector switch, which can be used to
monitor the condition of the batteries, especially when troubleshooting. Generally, a fully
charged battery will indicate approximately 12.8 volts with no loads connected. While
charging, the voltage will be in the range of 13.8 to 14.2 volts.
