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" Power Supply at all times.
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. Servicing of batteries should be performed or supervised by personnel knowledgeable of batteries and the required precautions.
Route unit power-cords so it cannot be walked on or damage. ELECTRICAL SPECIFICATIONS Electrical Specifications Battery Rated Output Time Max Heat Freq.

All Models: Operating Temperature 0ºC to 40ºC (32ºF to 104ºF) Storage Temperature -15ºC to 40ºC (5ºF to 104ºF) Relative Humidity 95% maximum at 25ºC Non-Condensing Audible Noise 40 dB ANSI Scale A, at 3' UNIT DESCRIPTION AT SYCHRONIZED SINEWAVE MODELS 1. Power Switch. 2. Alarm Silencer/Test momentary rocker switch. 3. AC Normal LED (Green): On when commercial voltage is present and in range (AC Normal Mode), off otherwise. 4.
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. Off as long as commercial voltage is present and in range, and frequency is stable. 6. Battery Status LED (Yellow/Red): Yellow at low battery warning. Red at low battery cutoff for one (1) second. Off otherwise. 7.
Turn on the UPS power switch ("1" position) and verify that the "AC Normal" LED (Green) illuminates after a short delay. This is the AC Normal Mode. Leave the UPS in this position for approximately 30 seconds minimum. Depress the UPS "Test/Alarm Silencer" rocker switch toward the "Test" position and hold for 10 to 15 seconds. Verify that the audible alarm sounds after a five (5) second delay (twice every two (2) seconds), the "AC Fault" LED turns yellow and the "AC Normal" LED extinguishes.
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" toward the "Alarm Silencer" position. The alarm will automatically reset upon return to the "AC Normal" mode, providing an audible indication of the next power problem.
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.
UPS DB9 PIN OUT PIN 2 -- SIMULATED CLOSURE to pin 8 at Utility Failure PIN 3 -- SIMULATED CLOSURE to Pin 8 at Low Battery Warning PIN 4 -- UPS INVERTER SHUTDOWN: When a high (+5VDC minimum) is provided for 10 msec. PIN 5 -- SIGNAL GROUND PIN 8 -- COMMON RETURN FOR PINS 2 AND 3 SERVICE If any problems are observed with your MINUTEMAN AT Series UPS, contact your supplier or Para Systems, Inc. Customer Service Department.
to identify a bad slow blow fuse visually. If the fuse is blown, replace it with a fuse of the same type and ratings. Reset breaker if tripped. Unit drops or reboots computer but continues to run in Inverter Mode. Unit is slightly overloaded. Disconnect some of the load and try again. Unit goes immediately to low battery warning. Batteries are bad or require a charge. Unit goes off when commercial power is interrupted -- no Inverter Mode function.
