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
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 --
CAUTION --
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.
-- UPS units use batteries for generation of AC voltages, so output receptacles
Do not remove the cover: there are no user-serviceable parts inside.
To prevent electrical shock, the 3-wire plug provides earth ground for the UPS

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 or battery pack.
These batteries have pressure-operated safety vents.

CAUTION --
and eyes and may be toxic.
CAUTION --
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:
1. Turn the UPS off and disconnect it from the wall outlet prior to connecting or
2. Remove watches, rings or other metal objects;
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. Released electrolyte is harmful to the skin
Although battery system voltages are only 24 or 48 volts, battery systems can

OPERATION
The UPS loads may be controlled by the UPS Power Switch if desired. For Model MM450, the
battery charger functions with the Power Switch on or off. For other models, the Power Switch
must be on for battery charge; consequently, these units may need to remain on overnight if
several power outages occurred during the day.
When a brownout, power interruption, power outage or over-voltage condition occurs, the alarm
will sound and the BATTERY IN USE light indicator will glow, indicating that commercial power is
lost or unacceptable and MINUTEMAN is now supplying power to your system. With a slower
intermittent audible alarm (approximately once every two seconds) and one or more green
BATTERY STATUS indicator lights on, the unit is in the normal Inverter mode (BATTERY
OPERATION). When the alarm sounds at more rapid intervals (approximately two per second)
and all green BATTERY STATUS lights extinguish, about two minutes of battery power remain. If
you have not already downloaded you system and turned it off, you must do so at this time. Then
the MINUTEMAN Power Switch should be turned off to prevent further battery discharge.
When commercial power returns, switch the MINUTEMAN power switch to the "On" position if it
was turned off previously. The green indicator light will come on after a short delay. Return your
system to operation, and the MINUTEMAN system will automatically recharge the internal
batteries during system operation.
Since most commercial power outages are of short duration, commercial power will probably be
restored before the two-minute warni ng

During normal AC operation, the MINUTEMAN Unit will quietly protect your system from power
surges, voltage spikes and noise interference. No alarms will sound and the green indicator light
will remain on during this operation.
SYSTEM BATTERIES
The internal batteries used in the MINUTEMAN UPS UNITS are sealed, maintenance-free, leadacid, with electrolyte totally absorbed in the plates and separator material. For maximum life,
battery temperature should be kept as cool as practical indoors, and at proper trickle charge
voltage.
Expected battery service is three to six years at 85ºF. For optimum performance, batteries
should be replaced after about three years. Replacement batteries can be purchased from Para
Systems, Inc. or from your local distributor or dealer. If the UPS is to be stored, allow the
batteries to fully charge for 24 hours; then store the unit in a cool, dry location. For extended
storage, recharge the batteries every four months. When the batteries are replaced, take the
used batteries to a recycle center for proper disposal and reclamation of the lead.
UPS MONITORING CONFIGURATIONS
All models provide an optional UPS monitoring capability (model suffix "K") which will allow direct
interface with many different computer operating systems. This capability permits an unattended,
orderly shut down of the computer system when commercial power is lost for a long period.
Some configurations also provide for a shut down of the UPS after the computer has been shut
down, thereby conserving UPS battery capability exists. Contact Para Systems sales department
for a more complete, up-to-date list.
Para Systems also offers its own software package "Network Manager," which functions with
Novell, UNIX-based, OS/2 and Macintosh operating systems. Network Manager offers many
advantages over existing UPS monitoring packages.
Finally, for systems which do not have UPS interface capabilities, user software can be written to
read UPS status and provide for system shut down. Software specialists should contact Para
Systems, Inc. for more information. The standard UPS DB9 PIN out is provided below for your
information.
