INTRODUCTION
Owner Orientation
The illustrations are for typical circumstances and are
meant to familiarize you with the installation options
available with your power management system.
Local codes, appearance, and distances are the factors that
must be considered when negotiating with an installation
professional.As the distance from the existing electrical
service increases, compensation in wiring materials must be
allowed for.This is necessary to comply with local codes
and overcome electrical voltage drops.
The factors mentioned above will have a direct
effect on the overall price of your power
management system installation.
NOTE:Your installer must check local codes AND obtain
permits before installing the system.
• Read and follow the instructions given in this manual.
• Follow a regular schedule in caring for and using your
power management system, as specified in the manual.
Installer Responsibilities
• Read and observe the safety rules.
• Read and follow the instructions given in this manual.
• Check federal, state and local codes.
• Consult with owner to determine loads to be controlled
and their priorities.
NOTE:A worksheet for determining which loads are to
be transferred and their priorities is provided on page 12.
• May need to provide appropriate rated contactors based
on loads to be controlled.
Equipment Description
The power management system is designed to control
six priority loads and up to two air conditioner loads that
are being supplied by power from the home standby
system.This power management system goes into a
STANDBY mode and does not control any loads when
utility power is present.
The power management system consists of a relay board
with 6 relays to control loads rated up to 120 VAC,
20 Amps, 1 hp, and a control module that has 2 relays for
central air conditioner loads.The circuit boards are housed
in a NEMA 3R enclosure that is suitable for both indoor
and outdoor installations.
Two (2) current transformers monitor generator current at
the transfer switch to ensure that the loading of the
generator does not exceed 85 percent. Should load exceed
85 percent, the power management system will start to
shed loads to keep the generator from overloading.The
power management system will add load back once
sufficient current is available.
The controle module has a green LED for each relay to
indicate when the relays are supplying power to the loads
when on generator power.There is also a status LED that
flashes when the power management system is functioning
properly.

SYSTEM OPERATION
When the home standby system is providing power to the
transfer switch, the power management system is
constantly monitoring generator power to control loads.
The power management system monitors both incoming
generator lines and keeps the home standby system loaded
to a maximum of 85-86 percent of rated load.When the
current transformers on any line start to see current reach
85-86 percent of rated load, the power management
system will start shedding loads based on the lowest
priority and work its way to the highest priority.When
current has dropped below 85-86 percent of rated load,
the power management system will start to add loads
based on the highest priority first, followed by the second
highest until the generator reaches 85-86 percent load or
all priorities are back on line.The power management
system will operate this way until the transfer switch
transfers back to utility position.
The power management system waits 5 seconds between
adding or shedding each load to permit the system to
stabilize.When a relay is opened, the relay will stay opened
for a minimum of 5 minutes or until the load can be added
without putting the generator over 85-86 percent of rated
load. If a large load demand is seen, the power management
system will shed loads at a quicker rate of less than
1.5 seconds to prevent the generator from overloading.
Once the demand has stabilized and the loads can be added
again, the power management system will start with the
highest priority, wait 5 seconds and then add the next
priority.The unit will continue to do this until all loads are
added or 85-86 percent of rated load is reached.
When the generator is powering loads, the A/C relays are
open.When one or both of the relays sense 24VAC from
the thermostat(s), the controller will shed loads B1-D2, and
then will allow only one A/C relay to close.A1 has priority
over A2. A2 can close when the signal for A1 has expired.
When the A/C’s are being called to run, all loads are to be
shed before the A/C unit can be added. Should A/C 1 call
while A/C 2 is running,A/C 2 shall open, all relays would
open and then A/C 1 can close.When the A/C relays open,
they are to be locked out for a minimum of 5 minutes or
until they receive a call to start the A/C.
TESTING THE POWER
MANAGEMENT SYSTEM
With the generator in “Auto“ position, turn the service
disconnect feeding the transfer switch contactor to the
“Off” position.The generator will start and the transfer
switch will transfer to generator power.
Press the test button on the controle module of the power
management system.As the button is pressed, a relay will
energize. Each time the button is pressed, the previous relay
that was energized, will de-energize and the next relay will
energize.
Press the test button once and relay B2 will energize. Press
the test button again and B2 will de-energize and relay C1
will energize.This will proceed until all relays have been
tested or if the test button has not been pressed for a
period of 30 seconds, the test sequence will halt and the
system will go back to automatic control.
To go back to utility power, turn the service disconnect
feeding the transfer switch contactor to the “On” position.
