Your UPS unit is shipped standard with SentryII monitoring software. This software may be
used for monitoring the UPS and power when loaded into your computer and connected via
the supplied software communication cable. This software is a detailed tool to help you
manage your power needs.
This software will also support a simpler style of controlled shutdown for the consumer that
is not interested in detail, but is still interested in a controlled unattended shutdown. The
simple software function requires the purchase and installation of a separate cable that is
not provided with the unit. Please contact your local vendor or Minuteman Technical support
department at 800-238-7272 or 972-446-7363 should you need to purchase this software
cable.
