Minuteman UPS XRT Series - Manual (Page 26)

WARNING EVENTS
Line Voltage Regulation
The UPS will warn you when the incoming utility power exceeds its
normal limits. On the LED front panel the Voltage Regulator LED will light,
indicating the incoming voltage is out of range. On the LCD front panel,
you will see a “Low Voltage In” or “High Voltage In” message. In either
case the audible alarm will not sound.
Output Voltage Switching
The Output of the UPS may be turned OFF or ON by any of three ways
other than the power switch. The XRT1000 and above output AC may be
manually turned on or off by selecting the Output On or Off command in
the SETUP menu. In all models the output may be turned on or off via the
RS-232 Serial port or by using the user supplied Output Power Off switch.
The XRT1000 and above units will notify you by the “OUT OFF Ext CNTL”
screen if the output was turned off from the RS-232 command, or “OUT
OFF Man CNTL” screen if the output was turned off from the Output Power
Off switch (see the SETUP menu section). The XRT600 does not have this
reporting feature, but if no power is being supplied from the UPS and the
AC Power LED is lit, then the probable reason is that the output has been
turned off.

The options available for the XRT series UPS’s are in three categories.
