       This driver supports the following optional settings in the ups.conf(5) file:

       testtime=num
           Change battery test time from the 2 minute default.

       offdelay=num
           Change shutdown delay time from 0 second default.

       This driver supports the following Instant Commands. (See upscmd(8))

   AllUPSunitsshutdown.return
           Turn off the load possibly after a delay and return when power is back.

       shutdown.stop
           Stop a shutdown in progress.

       shutdown.reboot
           Shut down the load briefly while rebooting the UPS.

       test.failure.start
           Starts a 15 second long simulation of an input power failure.

       test.battery.start.quick
           Start a "quick" battery test. The default time is 2 minutes. This time can be set in the ups.conf
           file. See testime above.

       test.battery.stop
           Stops a battery test that is in progress.

   AllONUPSunitsreset.input.minmax
           Reset the minimum and maximum input line voltage values seen since the last reset or power on.

   NewerONUPSunitstest.panel.start
           Start testing the UPS panel.

       test.battery.start.deep
           Start a "deep" battery test. This test runs the UPS until the low battery point and then returns to
           the AC line.

       reset.input.minmax
           Reset the minimum and maximum input line voltage values seen since the last reset or power on.

       beeper.enable
           Enable UPS beeper/buzzer.

       beeper.disable
           Disable UPS beeper/buzzer.

       beeper.mute
           Mutes the UPS beeper/buzzer for the current alarm condition(s).

Network UPS Tools 2.8.3                            07/08/2025                                           ONEAC(8)

       This driver supports various Oneac UPS families:

       •   EG (late 80s, early 90s, plug-in serial interface card)

       •   ON (early and mid-90s, plug-in serial interface card)

       •   OZ (mid-90s on, DB-25 std., interface slot)

       •   OB (early 2000’s on, big cabinet, DB-25 std., interface slot)

       If your UPS is equipped with the Basic Interface card, use the genericups(8) driver.

oneac -h

       oneac -a UPS_NAME [OPTIONS]

           Note

           This man page only documents the hardware-specific features of the oneac driver. For information
           about the core driver, see nutupsdrv(8).

       See upsrw(8) to see what variables are writable for the UPS.

           Note

           If your UPS supports writing battery.runtime.low, the new set value is to be entered in minutes (up
           to 99) but the reported value is reported in seconds (set value*60).

           Note

           If your UPS supports input.transfer.low and input.transfer.high, those values are used to create an
           allowable output range. The UPS will do what it can to keep the output voltage value within the
           defined range (for example: tap change or switch to inverter).
