Power unit and battery pack configurations
The DirectFlow UPS can be configured in the following ways:
•
DirectFlow power unit without any battery packs
The power unit can work as a standalone line conditioner, or active filter, that mitigates harmonics and
power factor for the input AC line that supplies utility or generator power. To set the power unit active
current correction (ACC) options, see the "UPS menu options (on page
73
)."
A configuration without battery packs does not supply power for extended runtime.
•
