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. Each unit is designed to be maintenance free and
to provide years of excellent service. Other features of the "AT" Series include:



Light weight and small footprint



Quiet operation



High non-linear current capability

(Crest Ratio = 3:1)



Computer grade sinewave output

LAN Communications Port

RECEIVING INSPECTION

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 the unit may later need to be returned to the factory or shipped to another location.

WARRANTY REGISTRATION

Locate your warranty registration card in the back of this manual and complete and return within
10 days of receipt of the unit(s) to register your warranty. Failure to register your warranty
renders it non-valid.

IMPORTANT SAFETY INSTRUCTIONS

Save these instructions

(



Units in this manual are intended for installation in a temperature-controlled, indoor area

free of conductive contaminants.



Read all instructions carefully before operating the UPS. All operating instructions should

be followed and all cautions must be adhered to.

CAUTION



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

unit chassis to prevent electrical shock. Plug the UPS unit into a 3-wire grounding type,
commercial receptacle with grounding conductor connected to earth ground at the
service equipment. Removal

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. Keep unauthorized personnel away from the
batteries.



When replacing UPS batteries, use sealed lead-calcium rechargeable batteries with the

same voltage and ampere-hour rating as those contained in the units. These batteries
have pressure operated safety vents.

CAUTION



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

2. Do not open or mutilate batteries. Released electrolyte is harmful to the skin and

3. Battery systems can present a risk of electrical shock and high short circuit current.

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

eyes, and may be toxic.

The current capability of each battery system is sufficient to burn large wire or tools
very rapidly, producing molten metal. The following precautions should be observed
when working on batteries:

a. Disconnect charging source prior to connecting or disconnecting battery

terminals.
b. Remove watches, rings or other metal objects.
c. Use tools with insulated handles.
d. Do not lay tools or any metal parts on top of batteries.
e. Wear protective gloves, eyewear, and boots.
f. Determine if the battery is inadvertently grounded. If inadvertently grounded,

remove source of ground. Contact with any part of a grounded battery can

result in an electrical shock. The likelihood of such shock will be reduced if

such grounds are removed during installation and maintenance.

SELECTION OF UPS LOCATION

Select a location that will provide good air circulation for the UPS. Do not cover the unit air vent
holes or restrict airflow in any way. The unit must have good air circulation at all times.



Avoid locations near heating devices.



Avoid locations near water or excessive humidity.



Avoid locations where the unit is exposed to direct sunlight.



Route unit power-cords so it cannot be walked on or damage.

* Input/Output specifications above for model AT1600 are applicable when a 20-ampere power
plug (NEMA 5-20P) is utilized (non-standard). For a NEMA 5-15P plug (standard), derate input to
120VAC/12 Amperes and derate output in "AC Normal" mode only to 120VAC/10.8 Amperes.
