INTRODUCTION

The MINUTEMAN ALLIANCE Series Uninterruptible Power Supply (UPS) has been designed to be
maintenance-free, and to provide years of excellent service. It will provide superior power
protection for personal computers, telephone systems and other critical electronic equipment
against all commercial power anomalies. Output waveform is a synchronized, simulated sinewave.
Both LED and audible alarms indicate UPS and commercial power status at all times. Other
features include:



Light weight and small footprint.



Quiet operation.



Excellent non-linear current capability.



LAN communications port (except A300).



Automatic UPS test at turn-on.



Site wiring fault indication (120 VAC models).



Low voltage boost to facilitate low commercial voltage operation without battery
utilization (except A300/A425).



Transfer voltage adjustment switches (except A300/A425).

RECEIVING INSPECTION

SAVE THE PACKING MATERIALS!

Remove and inspect the unit for shipping damage. If damage is found, immediately notify the
carrier and your dealer. If no damage is found, save both the shipping container and the packing
foam in case of a later need to return the unit to the factory, or ship it to another location.

WARRANTY REGISTRATION

Complete the warranty registration card provided in the back of this manual and mail it within ten
days of receipt to register your warranty.

Failure to register your warranty renders it non-valid.

IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS



Read this manual carefully before operating the UPS. All instructions should be followed
during installation and maintenance of the UPS and batteries.

1



These UPS units are intended for use in a temperature-controlled, indoor area free of
conductive contaminants. Select a location, which will provide good air circulation for the
UPS at all, times. Avoid locations near heating devices, water or excessive humidity, or
where unit is exposed to direct sunlight. Route power cords so they cannot be walked on
or damaged.



CAUTION

may be electrically hot even when the UPS is not connected to commercial power. Trained
service personnel should perform all repairs, since an electrical shock hazard exists.



CAUTION

-- The UPS uses batteries for generating AC voltages, so output receptacles

-- Do not remove the cover -- there are no user-serviceable parts inside.



CAUTION

chassis. Plug the UPS into a 3-wire grounding type, commercial receptacle with the
grounding conductor connected to earth ground at the service equipment. Removal of the
ground pin from the plug or use of a 3-wire-to-2-wire adapter will defeat this safety feature
and may result in a shock hazard. Additionally, if the plug is removed to simulate a power
failure (not recommended), do not touch the plug conductors or the chassis while the plug
is removed. On 120-volt models, improperly connected power will indicate a Site Wiring
Fault.



CAUTION

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. Keep unauthorized personnel away from the
batteries.



When replacing UPS batteries, use the same number of sealed lead-calcium rechargeable
batteries with the same voltage and ampere-hour ratings as those in the UPS. These
batteries have pressure operated safety vents.

CAUTION

CAUTION

and eyes and may be toxic.

-- To prevent electrical shock, the 3-wire plug provides earth ground for the UPS

-- Do not allow water or any foreign object to enter the UPS. In case this occurs,

-- Do not dispose of batteries in a fire. They may explode.

-- Do not open or mutilate batteries. Release electrolyte is harmful to the skin



CAUTION

battery system can still present a risk. The current capability of a battery is sufficient to
burn wire or tools very rapidly, producing molten metal. Observe these precautions when
working on batteries:

-- Although battery system voltages are only 12 VDC, 24 VDC and 36 VDC, the

1. Turn the UPS off and disconnect it form the wall outlet prior to connecting or
disconnecting battery terminals;

2. Remove watches, rings or other metal objects;

3. Use tools with insulated handles;

4. Wear protective gloves and eyewear;

5. Do not lay tools or other metal parts on top of batteries.
