Information:

Support Load InformationIf the UPS status is not "Online" or "Discharge", the load will not be protected during a utility outage. If the UPS Status is AVR or "Bypass", the load will be powered but not protected from a utility outage.If the UPS status is "Shutdown", the load will not have power for a certain amount of time regardless of the utility source.Note: The UPS will remain online as long as there are enough functioning flywheels to support the load. Therefore, any notice or alarm from a flywheel cabinet may not result in a UPS state change.
