The UPS displays a High
Input Current warning
message.
With a low input voltage, the
UPS compensates and
produces higher current to
maintain the power demand.
Access your UPS activity logs and look for any
consistent low voltage reading trends, which may
indicate a possible site issue. Reduce the load to
resolve any high current production stress to the
UPS.
For more information, refer to the NEXSYS UPS
Manager Software User Manual (100-00077) or
the NEXSYS UPS RackLink Network Card User
Manual (100-00074) at
