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.
