INTRODUCTION Congratulations on your purchase of a MINUTEMAN "AT" Series Synchronized Sinewave Uninterruptible Power Supply (UPS). Each unit is designed to provide superior, total power protection for personal computers, telephone systems and any other sensitive or critical electronic equipment against all commercial power anomalies. These models provide light and audible alarm indications, so the user will know the status of both commercial power and the MINUTEMAN "AT"...
the plug is removed to simulate a power failure (not recommended), do not touch the plug conductors or the chassis while the lug is removed. CAUTION -- Do not allow water or any foreign object to enter the UPS. In case this occurs, immediately turn the unit power switch off and unplug the MINUTEMAN from the commercial receptacle.
Route unit power-cords so it cannot be walked on or damage. ELECTRICAL SPECIFICATIONS Electrical Specifications Battery Time Max Heat Output System (Min) Dissipation Rated Output Freq. Input Back Up Model Watts VAC/A VAC/A Full Load Half Load BTU/HR AT650 120/6.0 120/5.4 GS650 220/3.3...

5. AC Fault LED (Yellow/Red): Yellow when commercial input voltage is lost or too low or input frequency shifts drastically and unit switches to inverter mode. Red when commercial input voltage is too high and unit switches to inverter mode Both stay on until fault is cleared.
AC fuse blows (AT650, AT800 or AT2300) or input breaker trips (AT1200 or AT 1600), the MINUTEMAN UPS will switch to the normal inverter mode - "AC Normal" LED will extinguish, audible alarm will sound after a five (5) second delay and the LED(s) indicating the problem will illuminate.
frequency shift will cause the "AC Fault" light to turn yellow and a blown fuse or tripped circuit breaker will cause the fuse/breaker light to illuminate (RED). The audible alarm can be silenced in both the "Normal Inverter" and the "Low Battery Warning" modes by depressing the "Test/Alarm Silencer Switch"...
BATTERY /SYSTEM CHECKOUT To verify proper system function and battery condition, the user is encouraged to engage the test switch periodically. Normal indications as specified should be observed. If the system goes immediately to the low battery-warning mode the batteries should be replaced. UPS MONITORING CONFIGURATIONS All of these models provide an UPS monitoring capability which will allow direct interface with many different computer hardware/software configurations.
