       fentonups - Driver for Fenton Technologies (Megatec protocol) UPS equipment

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

       fentonups primarily supports Fenton Technologies models such as	the  PowerPal,	PowerPure
       and  PowerOn  lines.   Due  to the common heritage of UPS equipment, it generally supports
       other hardware that also uses the Megatec protocol.

       At the time of this writing, the PowerGuard PG-600 and PowerCom	SMK-800A  are  recognized
       and  supported.	 Other	Megatec  units should also work, but they will generate a warning
       since their battery information is not known.

       This driver does not support any extra settings in the ups.conf(5).

       The battery percentage is derived from the voltage data that the UPS  returns,  since  the
       UPS  doesn't return that value directly.  On some hardware, the charge will remain at 100%
       for a long time and then drops quickly shortly before the battery runs out.  You can  con-
       firm from the BATTVOLT readings that this is a problem with the UPS and not this driver.

       Similarly,  the float from the charger in some models forces the battery charge percentage
       back up to 100% immedately after the UPS goes back on-line, so you can't tell when  it  is
       really recharged.

       Dead/broken batteries can't be reported reliably.  If your UPS kills the load instantly or
       within seconds of starting the inverter, your batteries	probably  need	to  be	replaced.
       Recently,  a pair of 3.5 hour outages here (thanks CPS!) finally killed my batteries.  You
       may have to run a manual test from the front panel before the "replace battery"	LED  will
