IMPORTANT NOTE: MAKE SURE TO READ, UNDERSTAND, AND FOLLOW

ALL ELECTRICAL COMPONENT OWNER’S MANUALS PROVIDED IN THE

OWNER’S PACKET BEFORE OPERATING THE MOTORHOME. Observe all

operating instructions and warnings as well as all recommended maintenance

schedules and procedures.

How The System Works

When you’re plugged into shoreline power or start your generator, 120-volt

current is fed to an Automatic Switch Over Box. Power from the box runs to the

120-volt circuit breakers on the Energy Management System. The module and

box are explained more in depth later in this chapter and are located under the

roadside rear lounge.

Circuit 4 can also be powered by the inverter part of the inverter/charger. See

circuit 4 function in the next section for information on which receptacles can

work on the inverter.

ENERGY MANAGEMENT SYSTEM (EMS)

A complete, detailed EMS manual is included with your owner’s packet.

Warning: The ENERGY MANAGEMENT SYSTEM is a

centralized power switching, fusing, and distribution center. Power from

the 120-volt power source is fed into the box. The potential of lethal

electrical shock is present in this box. Inadvertent shorts at this box

could result in damage and/or injury. All servicing of this box should be

done by a qualiﬁed Service Technician.

PRODUCT DESCRIPTION

The ENERGY MANAGEMENT SYSTEM is a completely self-contained 110

volt power distribution and energy management system intended to be used
