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 obser ve 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,
20Amps, 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.
