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.
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.
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.
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.
