INTRODUCTION

The MINUTEMAN 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 equipment, against all
commercial power anomalies.  Output waveform is a Synchronized Sinewave.  Both lamp and
audible alarms indicate UPS and commercial power status at all times.  Other features include:

  External battery pack options for extended battery runtime.

 Quiet 

operation

  Excellent non-linear current capability

  LAN communications port (optional)

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 to ship it to another location.

WARRANTY REGISTRATION

Complete the warranty registration card provided 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.

  These UPS units are intended for use in a temperature-controlled, indoor area free of

conductive contaminants.

  CAUTION -- UPS units use batteries for generation of AC voltages, so output receptacles

may be electrically hot even when UPS is not connected to commercial power.  All repairs
should be performed by trained service personnel, since an electrical shock hazard exists.

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

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

chassis. Plug the UPS into a 3-wire grounding type commercial receptacle with 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.
