PRODUCT DESCRIPTION
The is a completely self-contained 120 volt Power Distribution and Energy Management
System, intended for use in recreational vehicles. It is housed in a sheet metal enclosure with removable front panel.
It provides 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.
The offers slots for four single or dual, standard 120 volt circuit breakers. One of these
breakers must be a 30 Amp unit that acts as a main input protection for the remainder of the branch breakers (up
to 7).
The offers control of up to four, 120 volt operated appliances to help keep the total 120 volt
current draw to less than 30 Amps. 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.

HOW IT WORKS
The provides main and branch circuit protection control of up to four selected appliances.
The control helps to limit the total current draw of all the appliances in the R , at or below 30 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 four positions available for circuit breakers. These may be single, or dual units. One of these
breakers must be a 30 Amp unit to act as the Main breaker for the entire system. The 120 volt power is brought into
the box from either a shore cord, or generator. The line side of this cable is fed through the magnetically coupled
current transformer and connected to a 30 Amp circuit breaker that acts as the Main breaker. This breaker back-
feeds power into the circuit breaker bus to feed power to the branch breakers. These can be either single, or dual
circuit types. All the loads in the RV are fed from the branch breakers.
The current entering the main circuit breaker is routed through the magnetically coupled current sensor. This sensor
The RVIA (Recreational Vehicle Industry Association), in conjunction with the NEC (National Electrical Code),
require that a vehicle with 30 Amp service be equipped with a maximum of five 15 or 20 Amp circuit breakers unless
an energy management system is used. As a result, using the allows the use of two additional
breakers, enabling the vehicle to be equipped with additional circuits. It is also required that the energy management
system must limit the average current entering the main circuit breaker over a three-hour period to 80% of the 20 or
30 Amp service rating. Therefore, if
exceeds 80% of 30Amps (24Amps) when 30Aservice is selected, or 80% of 20 Amps (16Amps) when 20A service is
selected, the will automatically change the service limit to 80% of the selected service.
Correspondingly, the will restore the service limit to the full 30 or 20 Amp value when the average
current drops below 80% of the service rating. When the lowered service limits are enabled as a result of average
current exceeding 80% of the service rating, the decimal point in the lower right-hand corner of the Load Meter on the
Display Module will be lit.
In addition, the has the capability of using the energy management feature when
the gen-set is the power source, preventing gen-set circuit breaker tripping and overload. The Control Module can
be configured by the installer to enable this feature using the configuration dip-switch (See Page 4).

CONTROLLED LOADS
EMS
the Load Meter indicates the amount of current actually being drawn
The system offers control of up to four 120 VAC powered loads. Loads that are to be controlled are connected to one of
the relay circuits of the . There are five total control relays in the EMS. ONLY 4 of these can be used in a given
application.
Two of these five circuits have single-pole double-throw, low voltage relays, with un-dedicated contacts available.
These are intended to control air conditioners, or other appliances equipped with low voltage controls, or thermostats.
The contacts of the relays are typically wired in series with the thermostats of air conditioners, so the EMS turns off only
the compressor. This leaves the fan on to re-circulate the air, masking the interruption of the compressor. These relay
circuits could also control other 120 volt appliances, if an additional control relay is added externally.
Three of these circuits are 15 Amp relays to interrupt the 120 volt power to the loads. These circuits are intended to
control 120 volt appliances such as water heater, washer/dryer, coffee maker, etc. For the 120 switched loads, power is
routed from the individual branch circuit breakers to one of these 120 volt relays. The controlled load is then fed from
that relay.
In operation, when the 120 VAC and 12 VDC are initially applied, the system will energize the relays at one second
intervals, closing the normally-open contacts on each of the five relays while monitoring the total current. If the total
should exceeds the service limit, the system will turn off the last load that was turned on. As it does this, it calculates the
amount of current that was removed, which is the value for that load. This value is placed in memory. The system has
"learned" the amount of current that particular appliance draws. This feature compensates for the differences in current
draw over a range of line voltage and ambient temperature, by re-learning the load each time it is turned off.
The system now waits until the total current is lower than the service limit, by the amount in memory, before it will turn
that load back on. This assures that there is sufficient current to operate the load.
The optional display panel, can be mounted remotely and connects to the main unit with a small gauge, three wire
cable.
Four Power Status LED's indicate power is applied to those loads. These LED's are on when the power is applied. A
two digit display, , by all the appliances in the
coach.
OPERATION
NOTE: two-minute minimum delay ,There is a period after a load is shed before the load can be turned back on
again to prevent air conditioners from turning on with a head of pressure. During this delay period, if there is enough
current available to energize the load, the LED status indicator for that load will flash. After the delay period expires, the
load will be energized and the indicator will turn on.

The “Service Select” button allows the service type to be set to either 30Amps
or 20Amps, to match the incoming service. If the pictured adaptor is used on the
incoming service, press the “Service Select” button to select the 20Amp mode.
When power is first applied, the system will always be in the 30Amp mode.
The 30/20Amp indicator LED will be ON when the system is in the 30 Amp mode.
Momentarily pressing this button will switch the system to the 20Amp mode.
Momentarily pressing this button again, will switch the system back to the
30Amp mode.
This panel can also be used to display the value of current stored in memory for each of the four loads. To
display the values of current stored in memory for each of the four loads, push and hold the “Service Select”
button for a minimum of 2 seconds and release it. The last selected load LED will illuminate and the stored
value will appear on the Load Meter. Pushing “Service Select” again, will cycle to the next load. If the unit is in
the three-hour averaging mode, indicated by a lit decimal point at the lower right corner of the Load Meter, the
display will cycle to display average current when no load LED’s are lit. If a period of 5 seconds elapses
between button presses, the Load Meter will return to normal operation and display total current draw.
The first step when installing an EMS, is to determine which loads will be controlled and in what order they will be
shed. A typical scheme would be to control the two air conditioners, the water heater, and the washer/dryer. With
these loads, the first load to be shed should be the water heater, as its loss of operation would be the least noticed. It
would switch to operate on gas if needed. The next would be the bedroom air. The third would be the washer dryer
and finally the main air. Choosing this sequence would provide the least inconvenience to the occupants.
INSTALLATION
The EMS Control Module has an eight position dip-switch (S1) on the board to configure the features active in the
system. The switches in positions 1 thru 3 determine the order of shedding of the loads (See next page). Placing the
switch in position 4 in the “OFF” position enables the energy management feature when the gen set is running and
the setting of the switch in position 5 determines the service rating when the gen set is running. If the switch in
position 5 is in the “ON” position the service limit is 20Amps (2.5kW), if it is “OFF” the service limit is 30 Amps (3.6kW).
Additional switches in positions 6 thru 8 are reserved for future control configurations.

The dip-switches position 1 thru 5 are all preset to “ON” at the factory. Changing the setting of S1-1, S1-2, or S1-3 will
alter the order of shedding to suit the particular need of the installation. The tables below will assist in determining
the proper settings for S1-1 thru S1-3.
Next, looking across the other eight columns, find the one that matches the "Load Type" column you just filled in.
Using the number at the top of the column, look in the table below to determine the settings of the three switches, S1-
1, S1-2, and S1-3. An "ON" means the switch should be closed, and an "OFF" means the switch should be open.
The first step is to fill in the blanks with the names of the loads you want the system to shed, in the order they are to be
shed, with the first to be shed at the top. Then, fill in the second, "Load Type", column with an "A" or a "D", an "A" for a
120 VAC controlled load such as a washer/dryer, or a "D" for DC controlled load, such as a thermostat wire. You can
select a maximum of 3AC\1 DC relays, or 2 AC\2 DC relays.
At the bottom of each column is the Relay Shed Order. This determines which relays will be used for each load. The
one at the top of the column is first to be shed. The one below it will turn off next and so forth. The loads be
wired in this order for the system to operate as desired.
Finally, the number and size of the circuit breakers should be selected to meet the needs of the installation. The
breakers can be either single, or dual types. One of these breakers MUST be a 30 Amp unit to act as the Main
breaker. The breakers must be obtained and then installed in the box.

PLACEMENT
The EMS should be installed in a convenient location where it can get air
circulation to keep it from over heating. There should be a minimum of 7" of
depth behind the mounting surface to provide enough room for the box and
wiring.
Ahole should be cut in the mounting panel as shown.
This opening must be cut carefully to be sure the mounting screws will have
enough wood to hold and that there is enough clearance around the box for
the front cover screws.
The wiring to the box should be routed through the holes in the back and
secured using approved cable connectors. The wires should be copper
conductors with the appropriate size and insulation to meet N.E.C.
The 10 gauge main cable should be brought through the large hole in the lower center of the box. The remaining
wires should be routed through the remaining holes in the back of the box.
The wires should be stripped and the ground wire of each cable connected to the GROUND bar, terminal strip. The
white or neutral wires should all be connected to the NEUTRAL bar terminal strip. Each terminal screw should be
tightened per the torque table on the front cover of the EMS.
If removed during installation, the white jumper wire should be re-installed between the NEUTRAL bar and J6,
terminal 5 of the EMS module. (See box drawing, page 6.)
The Black or "hot" lead should be routed through the hole in the current sensor and then to the screw terminal on the
30Amp Main breaker.
The black or "hot" leads of all the uncontrolled loads should be connected to their associated breakers.
To connect the 120 volt controlled loads, jumper wires should be connected from the respective circuit breakers to
the associated screw terminals on the EMS control module. The black wires to the controlled loads should be
connected to the proper screw terminals on the EMS module. Be sure these wires are under the screw terminals and
they are tightened to 14 +/-2 in.-lbs.

The low voltage controlled load relay connections are typically made to the thermostat wires of the air conditioners.
The Normally Open contacts are wired in "series" with the thermostat. This means that the thermostat wire is cut and
the two ends are wired to the Common and the Normally Open contacts of the relay/s. In this way, the EMS can
interrupt the operation of the compressor, just as the thermostat does. The low voltage wires are brought into the box
through the large hole in the lower right-hand corner of the back of the box.
1) If only the compressors of the front and rearA/C's are to be controlled, connections are typically made to the low
voltage compressor control wires of the air conditioners. The normally closed contacts are wired in "series" with
the compressor control lead. This means that the compressor control wire is cut and the two ends are wired to the
Common and the Normally Closed contacts of Relay 5 or 6. In this way, the EMS can interrupt the operation of the
compressor, just as the thermostat does.
2) If both the compressors and fans of the front and rear A/C's are to be controlled, connections are typically made to
the low voltage thermostat control wires of the air conditioners. The Normally Closed contacts are wired in
"series" with each thermostat control lead. This means that the thermostat control wire is cut and the two ends are
wired to the Common and the Normally Closed contacts of Relay 5, or 6. In this way, the EMS can interrupt the
operation of the compressor and fans, just as the thermostat does.
3) If the compressor and fan for one of the A/C systems are to be controlled individually, connections are typically
made to the individual low voltage thermostat control wires for the fan and compressor of the air conditioner. The
Relay 6 connections are typically made to the low voltage compressor control wires of the air conditioner to
control the compressor. The normally closed contacts are wired in "series" with the compressor control lead.
This means that the low voltage compressor control wire is cut and the two ends are wired to the Common and the
Normally Closed contacts on Relay 6. The Relay 5 connections are typically made to the low voltage thermostat

Finally, on the Control Module, there is a small 2 pin plug labeled J1 which is only used for the High Pot Test on
the system. When the two pins are shorted together, the EMS will operate without the presence of 120 VAC.
Now the should be moved into the mounting hole, being careful not pinch any of the wires. It should be screwed
in place using four # 8, round head screws into the 4 holes in the side flanges. The front cover should be secured into
place with the 6 screws provided in the holes in the top and bottom flanges.
The Display Panel is equipped with a six inch long pigtail with a 3-pin
Mate-N-Lock female connector. An extension harness up to 100 feet
long can be attached between the Display Panel and the EMS Control
Module, with a 3-pin male Mate-N-Lock plug at the Display Panel end
and a 4-pin male Mate-N-Lock plug at the Control Module end.
The wiring of the plug at the Control Module end determines the system
configuration as follows:
1)
Pins 1 thru 3 on the 3-pin plug connect to the corresponding pins on the 4-pin plug.
2)
Pins 1 thru 3 on the 3-pin plug connect to corresponding wires in the RV Multiplex system and the corresponding
pins on the 4-pin plug. The consumes Modules A, B, and C signals for communications,
therefore, no other devices in the system may be assigned as these Modules.

low voltage side of the Control Module printed circuit board. The consumes Modules A, B,
and C signals for communications, therefore, no other devices in the system may be assigned as these Modules.
The Display Panel should be plugged onto the mating three-pin Mate-N-Lock connector in the harness, insuring that
it is fully seated and locked. The panel should then be installed in the hole and screwed in place using two # 6, flat
head screws through the holes in the panel. A white function label should be lettered to correspond to the order of

PERFORMANCE TEST
CIRCUIT BREAKERS
The system is now ready for testing.
At the installers preference, to assure there are no potential shorts, a Hi-Pot test can be performed on the installation.
To do this, +12 volts must be applied to the system. A jumper wire must be installed to tie the two pins of the "Hi-Pot
Test" plug, J1, to turn the system on without the presence of 120 volt power. This plug is located on the right side of
the EMS Control module The relays on the module should be heard clicking as they pull in.
(If the system is equipped with a Display Panel, the LED's should light and the numeric display should read "0".) The
Hi-Pot test should now be conducted in accordance with standard procedures for the tester being used. Assuming
the system passes, the covers should be taken off and the jumper removed from J1. If not, the problem must be
corrected before proceeding further.
All the 120 volt loads should be turned off or disconnected. Both 120 volt AC and 12 volt DC power should now be
applied to the system. When this is done, the relays should be heard pulling in, one at a time, at one-second
intervals.. If the system is equipped with a Display Panel, the numeric display should read "0" and the four LED's
should be come in order. If the system is not equipped with a display panel, a clamp-on type ammeter should be
used to measure the current being supplied by the 30Amp shore power cord.
Connect or turn on one of the controlled AC loads. It should operate and the numeric display or the clamp-on
ammeter should show the amount of current that load is drawn. Turn that appliance off and repeat this with each of
the others.
To test the load shedding, turn on all the controlled appliances. The total current drawn should exceed 30 Amps. (If
not, add additional loads to the non-controlled receptacles.) When the total amount of current exceeds 30 Amps,
the loads should begin to turn off to bring the total below 30Amps.
There are 4 positions for the circuit breakers in the box. The circuit breakers can be single, or dual types.
One must be a 30Amp to be used as the Main Breaker.
The following breakers are suitable for MAIN and BRANCH breakers:
