Consumption Of 120-Volt Ac Power; 12-Volt Dc System; Converter; Auxiliary Battery (Dealer Installed Option) - Jayco COVE 2002 Owner's Manual

Consumption of 120-volt AC Power

As owners desire and purchase more appliances as we have in our home, we must remember a park
trailer has only 30-amps of incoming power available. Conserving and choosing which appliance
has priority in consumption needs to be part of planning. Items such as toasters, skillets, coffee pots,
etc. all need to be included in the consumption of power

12-Volt DC System

The 12-volt DC system is composed of numerous items such as converter, battery, fuses, wire, and
bulbs, both interior and exterior lighting. Explanation on these items will follow in this section.
#
CAUTION: For the breakaway switch to be operational, an auxiliary battery needs to be
installed. Consult with your dealer to purchase the battery and have it installed.
#
CAUTION: Your park trailer has many 12-volt DC loads. When combined, they total more
power consumption than is available with the 12-volt DC converter. Periodic overloads can
be handled with the additional auxiliary battery for short periods of time. It is suggested to
conserve your 12-volt DC system at most times. Prolonged overload may shorten the
performance life of converter.

Converter

A converter utilizes 120-volt AC power and transforms this energy into 12-volt DC power, which is
used inside of your park trailer. 12-volt DC energy supplies power to all interior lights and various
appliances. The floor plan, and size of the park trailer dictates the model and output size of the
converter required.
Inside of the converter is an electronic device which automatically switches between 120-volt AC
incoming power and battery power. An auxiliary battery as correctly installed will be charged when
the park trailer is connected up to 120-volt AC power. The converter will supply power through the
fuse panel located near by, possibly in the same compartment.

Auxiliary Battery (Dealer Installed Option)

All Jayco park trailers are designed and built to accept a battery. A deep cycle marine type is
recommended as you need longer energy rather than cold cranking power. A battery is required to
operate the breakaway switch and is also available as a source of energy when traveling.
All battery packages require an "in-line" fuse and holder attached to the battery for protection.
Maintenance on a battery is required for longer life. First, all terminals need to be kept clean and free
of corrosion. Second, a battery that is used daily or has the converter in operation will consume
water. Keep the battery filled as the cells cannot hold a charge when the water is low. A deep cycle
battery is NOT maintenance free.
