Introduction The APC SymmetraTM Power Array is a scalable, redundant power protection system for multiple servers and business critical applications. This is an introduction to the SymmetraTM Power Array.
Thank You! Theory of Operation Thank you for investing in the SymmetraTM Power Array. Please read this User's Manual thoroughly prior to installing the system. It provides important information about installing and using the SymmetraTM safely and effectively. The SymmetraTM Power Array is comprised of three functional components: A power processing system, a battery source, and a control/user interface system. Output power is routed through a transformer prior to delivery to the load equipment.
Power Processing System Control/User Interface The power processing system delivers conditioned AC output power with a low distortion sinewave. Under normal operating conditions, power is received from the AC utility power source, conditioned by the power processing system, and delivered to the load equipment.
Modes of Operation On-Line Operating Mode The Power Array functions in one of four modes of operation, depending on user commands, the status of the AC utility voltage, and the condition of the SymmetraTM itself. The four modes are Load-Disconnect, On-Line, On-Battery, and Bypass. The PowerView interface reports the operating mode. The on-line operating mode is the “normal” operating mode.
On-Battery Operating Mode Bypass Operating Mode When in the on-battery mode, the Power Array draws DC power from the battery source, converts it to conditioned AC power that is then delivered to the load equipment. SymmetraTM typically enters this mode in the event of a utility power failure. It will also operate in the on-battery mode during a user initiated battery self test.
Definitions Important Information The following definitions are used in this manual and will be helpful in understanding SymmetraTM. Please read this User's Manual thoroughly, before proceeding with the installation of the SymmetraTM Power Array system. It provides important information about installing and using the SymmetraTM safely and effectively. Pay close attention to text that is accompanied by a danger, or caution symbol.
