Alternators; Battery Charger; Ac Electrical System; Shore Power - Maxum 3700 SCR Supplemental Owner's Manual

Alternators

When the engines are running, the alternators installed on your yacht maintain proper charge levels in the engine and
accessory batteries.

Battery Charger

• Your yacht is equipped with a battery charger, located inside
the engine room.
• The battery charger's circuit breaker is located on the AC panel and
must be turned on for charging to occur.
• The battery charger will charge the yacht's batteries whenever the
boat is plugged into 120 volt shore power or whenever the optional
generator is operated.
• We recommend that you thoroughly read and understand the battery
charger manual (provided in your yacht's owner's packet) before
using the charger.
The battery charging systems (alternators and battery charger) installed are designed to
charge conventional lead-acid batteries. Before installing gel-cell or other new technology
batteries, consult with the battery manufacturer about charging systems requirements.

AC Electrical System

• Your yacht uses 120v AC/60Hz or optional 240v AC/60Hz systems.
• Τ he AC system can be energized by shore power or optional generator power.
• The power source is selected using the master circuit breakers. After activating AC power, individual breakers
must be activated to supply power to the accessories you wish to use.
• This system is designed so that ship's power and shore power sources cannot supply power simultaneously.
• DO NOT energize the AC water heater electrical circuit until the heater is completely filled
with water. Even momentary operation in a dry tank will damage the heating elements.
Warranty replacements will not be made on elements or tank damaged in this manner. The
tank is full if water flows from the tap when the hot water is turned on in the galley.
• When using shore power or (optional) generator power, the simultaneous operation of
several AC accessories can result in an overloaded circuit. It may be necessary to turn off
one accessory while operating another.

Shore Power

• Your yacht is equipped with dual dock-
side inlets which are rated 120v/30
amps or optional 240v/50 amps.
• Dockside inlets are located inside the
starboard transom storage tub.
• Since some dockside receptacles may
be rated less than 30 amps, you may
need to purchase lower amp adapters.
Whenever a lower amp adapter is used,
however, there will be a corresponding
drop in supplied power from the dock-
side system.
