years at 85°F. We recommend replacement after 3 years of use. Replacement batteries can be
purchased from Para Systems, Inc. or from your local distributor or dealer.
1.
MINUTEMAN batteries must not be left in a discharged state with the unit power
switch “on” for longer than 72 hours. Further, the batteries must not be left in a
discharged state with the power switch “off” for longer than 30 days. Either
situation can cause permanent damage to the batteries and will void the battery
warranty.
2.
If the unit must be stored, the internal batteries must be fully charged prior to
storage. Store the unit in a cool, dry location, For extended storage, the unit must
be removed from storage periodically for battery charge. With a storage
temperature of 40°C (104°F), charge the unit 24 hours every 4 months. Cooler
storage temperatures increase the length of time between recharge cycles.
BATTERY/SYSTEM CHECKOUT
To verify proper system function and battery condition, the user is encouraged to repeat
Steps 6 and 7 of the INSTALLATION AND TEST PROCEDURE periodically. Normal
indications as specified should be observed. If the system goes immediately to the 2-
minute warning mode, the batteries should be replaced.
UPS MONITORING CONFIGURATIONS
MM500 units in this manual provide a UPS monitoring capability option which will allow
direct interface with many different computer hardware/software configurations. This
capability permits an unattended, orderly shutdown of the computer system when
commercial power is lost for a long period. Some configurations also provide for a timed
delay shutdown of the UPS after the computer has been shut down, thereby conserving
UPS battery capability.
Following is a partial list of systems with which the monitoring capability exists, along with
the Para Systems interface part number required for each. Contact Para Systems sales
department for a more complete, up-to-date list. In addition to those configurations listed
below, Para Systems also offers its own software package, “Network Manager”, which
functions with Novell O/S 2.11 and above and SCO Xenix O/S 2.2.3 and above. This
system offers many advantages over most existing UPS monitoring packages. Most all of
these monitoring interface systems can be used to control multiple file servers.
Finally, for systems that do not have UPS interface capability, user software can be
written to read UPS status and provide for system shutdown. Software specialists should
contact Para Systems, Inc. for more information.
