.SH "SUPPORTED HARDWARE"
.sp
This driver should support the PhoenixContact QUINT\-UPS industrial DC UPS, model 2320461 and all compatible models\&. More information about this UPS can be found here: https://www\&.phoenixcontact\&.com/online/portal/us?uri=pxc\-oc\-itemdetail:pid=2320461
.sp
phoenixcontact_modbus uses the libmodbus project, for Modbus implementation\&.
.SH "HOW TO CONFIGURE THE UPS"
.sp
Note: this UPS and its manual refers to Low\-Batt as "Shutdown Event"\&.
.sp
You need the "IFS\-RS232\-DATACABLE" to communicate with the UPS in Linux as the IFS\-USB cable doesn\(cqt seem to be supported\&. FYI communication parameters are: 115200,E,8,1\&.
.sp
You also need the UPS\-CONF Windows software (free; download from their site), to configure the UPS signals and timers\&.

When remaining battery time is less than 5 minutes (PC\-Shutdown setting), it will raise the "Shutdown" event (seen as LOW\-BATT in NUT)

When the input power is restored, the UPS will restore output power after 60 seconds (PC\-RESTART delay setting)\&.

PC\-Shutdown: How long before output cutoff the UPS will raise the "shutdown event" signal\&. Max value for this is 5 minutes\&. So PC should be able to shutdown within 5 minutes\&.

.RE
.SH "EXTRA ARGUMENTS"
.sp
This driver doesn\(cqt support any optional settings\&.
.SH "INSTALLATION"
.sp
This driver is not built by default\&. You can build it by installing libmodbus and running configure \-\-with\-modbus=yes\&.
.sp
You also need to give proper permissions on the local serial device file (/dev/ttyS0 for example) to allow the NUT user to access it\&.
.SH "INSTANT COMMANDS"
.sp
This driver doesn\(cqt support any instant commands\&.
