The UPS shall be protected against sudden changes in output load and short circuits at the output terminals. The UPS shall have built-in protection against permanent damage to itself and the connected load for all predictable types of malfunctions. Fast-acting current limiting devices shall be used to protect against cascading failure of solid-state devices. Internal UPS malfunctions shall cause the module to trip off-line with minimum damage to the module and provide maximum information to maintenance personnel regarding the reason for tripping off line. The load shall be automatically transferred to the bypass line uninterrupted, should the connected critical load exceed the capacity of the available on-line modules. The status of protective devices shall be indicated on a graphic display screen on the front of the unit.

Ten times continuous load rating for three cycles without closing the bypass breaker.

              2. Output Voltage Transients. Voltage transients shall be limited to a maximum deviation from nominal system output volts of ±7% with recovery to within 1% of the nominal output voltage within 50 milliseconds for each of the following conditions. Limits shall apply to any UPS load within the UPS rating and frequency shall be maintained at 60 Hertz plus or minus 0.1 hertz. The system shall not transfer to bypass under these conditions (except item c below).

                1. 100% load step.

                2. Loss or return of AC input power, momentary sags, surges or spikes on the input to the UPS (all three phases or single phase).

            6. Sensors. Temperature sensors shall be provided to monitor UPS internal temperature. Upon detection of temperatures in excess of manufacturer's recommendations, the sensors shall cause audible and visual alarms to be sounded on the UPS control panel.
