    1. UPS MODES OF OPERATION

        1. Standard: Power strategy set for High Efficiency: Utilizing commercial AC power, the critical load shall be continuously supplied regulated and protected AC power. The system shall power the load while regulating both voltage and frequency in compliance with the UPS output specifications (Section 2.2C). The system shall derive power from the commercial AC source if the input source is within the specifications for the UPS input. Upon loss of AC power or an event where the input AC source is not is tolerance the UPS shall supply DC power to the Inverter which will supply an output voltage in compliance with the output voltage specifications. System efficiency will be 97% or greater, over the range of 40% to 100% load. System efficiency will be 95% or better from 20 to 40% load. The UPS shall be able to distinguish between upstream (utility) faults and downstream (load) faults, and react appropriately to protect and support the critical load, without interruption. When High Efficiency is utilized, the UPS must attenuate ANSI C62.41-type line transients to within IEC and ITIC limits. During standard operation the AC source shall provide power for the loads in conjunction with charging the battery.

        2. Normal: Power strategy set for Normal: Utilizing commercial AC power, the critical load shall be continuously supplied regulated and protected AC power. The system shall power the load while regulating both voltage and frequency in compliance with the UPS output specifications (Section 2.2C). The system shall operate in double conversion mode of operation unless forced or commanded to battery mode, bypass mode, high efficiency more or system off. The system shall derive power from the commercial AC source and shall supply DC power to the Inverter in conjunction with charging the battery. All systems shall be capable of changing between normal and high efficiency modes from the front panel of the UPS system. There shall be no time restraints for normal mode operation.

        3. Battery: Upon failure of the commercial AC power, the critical load shall continue to be supplied AC power by the system, which shall obtain power from the batteries without any operator intervention. Continuous operation of the critical load shall never be jeopardized during the failure or restoration of the commercial AC source.

        4. Charger: Upon restoration of the commercial AC or back-up generation source, the charger shall recharge the batteries and simultaneously supply power to the input power converter (rectifier) which provides power to the Inverter. This shall be an automatic function and shall cause no interruption to the critical load.

        5. Static Bypass: Each UPS power module shall incorporate a continuous duty static bypass to provide transfer of critical load from the inverter output to the bypass source. This transfer, along with its retransfer, shall have no effect on the operation of the critical load. In the event of an emergency, this transfer shall be an automatic function.

        6. Maintenance Bypass: Each UPS module shall be equipped with an intelligent automated internal make-before-break maintenance bypass to isolate the UPS during routine maintenance and service of the UPS electronics or battery modules. The maintenance bypass shall be powered by a separate power supply, not part of the removable electronics module.
