PRODUCT DESCRIPTION
The consists of two elements: the and the Model
800 The Display Panel is mounted on a wall, or suitable surface remotely from the Distribution Panel
and convenient to the user The Model 800 Distribution Panel is a completely self-contained 120/240 volt power
distribution and energy management system intended to be used in recreational vehicles. It is housed in a sheet metal
enclosure with removable front panel providing circuit protection for all the 120 VAC loads in the RV and a system of energy
management to minimize the over-loading and tripping of circuit breakers. In addition, the Model 800 Distribution Panel
incorporates a sub-panel to accommodate inverter/converter connected loads.
The 50 Amp Smart EMS Model 800 automatically senses the available power to the vehicle and determines whether it is
connected to a 120 VAC - 30 Amp shore power source, 240 VAC - 50 Amp shore power source, or Generator source.
Depending upon available power, it controls the operation of 6 possible loads that may include: the front and rear air
conditioner fan and compressor using low voltage switching and other 120 Volt loads, such as the refrigerator, water heater,
washer/dryer, microwave oven, or other large appliances. These appliances may be any type load, but are typically
heavier loads, those whose use can be “postponed” until a time when current is available for their use. If the available power
source is 120 VAC - 30Amp shore power, it attempts to keep the total 120 volt current draw to less than 30 Amps.

The provides main circuit protection for 120/240 VAC single-phase incoming lines and
branch circuit protection for up to 12 circuits, including Energy Management of up to six selected branch circuits. A sub-
panel is available on the Model 800 for up to 6 sub-breakers for inverter connected loads. If 120 VAC - 30/20 Amp source is
available, the control helps to limit the total current draw of all the appliances in the RV at or below 30/20 Amps provided by
the main power feed.
Circuit protection for ALL the 120 VAC loads is offered by standard, reset-able circuit breakers, provided by the installer.
There are eight positions available for circuit breakers on the Main Distribution Panel. The breakers located in the two
center stab positions must be 50 Amp breakers to act as the main breakers for the entire system. These breakers back-
feed power into the circuit breaker bus to feed power to the branch breakers. The remaining six positions on the Main
Distribution Panel may be occupied by single or dual units. All the loads in the RV, including the inverter/converter, are fed
from the branch breakers. The 120 VAC output of the inverter is fed to a sub-panel containing three positions that may be
occupied by single or dual units
The utilizes Intellitec’s RV Multiplex/PMC (Programmable Multiplex Control)
System as the communications link between the l and the As an additional diagnostic
feature, the system includes two Communication Status LED’s on the Control Module. In normal operation, when the
is configured in the Stand-Alone Mode, or as the RV Multiplex system, the green “IPX OK” LED should be
lit and the red “IPX Fail” LED should not be lit.
Utilizing the RV Multiplex/PMC system, the Smart EMS System can:
1) Operate as a Stand-Alone system.
2) Operate as a RV Multiplex System Master in a RV Multiplex System, allowing other devices such as
Inverter/converters, input and output modules, and switch panels, to communicate with each other and the Smart
EMS System.
3) Operate as a PMC Transceiver with the addition of a PMC Central Processing Unit (CPU).
The main neutral line is routed through the magnetically coupled current sensor, which measures the current flowing
through the neutral line. This is the total amount being drawn by all the 120 volt appliances in the RV when the available
power service is 120 VAC. When this current exceeds the "shore" service rating of 30 Amps (20 Amps if the threshold has
been set lower or the generator service rating and 240 VAC service is not available, the will turn off
the controlled loads in an effort to bring the total current to the limit of the incoming service.
