has triggered. If the SOH reaches 0%, the UPS will allow pass-through power but will no longer provide
backup power.

Clicking the “EVENTS” button will access the Event Log.
5.4.8.1.
EVENT LOG
The event log records internal UPS events. UPS conditions are checked on power up and any
required log entries are added to the log. Additional entries are added as the conditions
(events) occur. A time-stamp reflecting the UPS up-time are pre-pended to each log entry. If an
error code is available, it will also be pre-pended to the log entry.
The “End of Service Life” warning is captured in the event log. This is a pre-warning to notify the
user that the UPS is approaching its End of Life. When this event is triggered, the user should
order a replacement UPS. After receiving the replacement UPS, it is recommended to schedule
a maintenance time to replace the UPS producing this warning before the SOH field has reached
0%. Failure to replace the UPS before SOH reaches 0% will result in loss of UPS backup power.
The “End of Life” event is captured in the event log. This message notifies the user that the UPS
is no longer able to support backup power. When this event has triggered, the user should
replace this UPS as soon as possible as the system is operating without backup power.
The “Cell Over-Voltage, Cell(s) #cc Voltage(s) v.v” failure is captured in the event log. The entry
indicates the cell(s) that have an over-voltage and the value of voltage that appeared on the
cell(s). This is typically a hardware fault condition. The UPS will continue to provide pass-
through power, but the UPS backup power will be permanently disabled. Contact Panduit
Customer support for the next steps to be taken.
The “Cell Over-Temperature, tt°C” failure is captured in the event log. The excess temperature
experienced by this UPS has damaged the ELDC capacitors in the UPS. This is a notification to
the user that the UPS is no longer able to support backup power. When this event has triggered,
the user should replace the UPS as soon as possible as the system is currently operating without
backup power.
The “UPS Temperature Above Safe Limits, tt°C” warning is captured in the event log. The unsafe
temperature experienced by the UPS is close to damaging the ELDC capacitors in the UPS. The
user should reduce the ambient temperature around the UPS to avoid over-temperature
failure.
The “UPS Temperature Return to Safe Limits, tt°C” event is captured in the event log. The
unsafe temperature experienced by the UPS has fallen into the safe range for the UPS.
The event log also records events pertaining to the automatic cell-balancing. The event log
records when the automatic cell-balancing routine is activated or de-activated, when an under
or overvoltage condition is detected, or when bleed resistors are turned on or off (bleed
resistor are used to balance the cells). No action is required because of cell balancing. Cell
balancing is a common event that happens throughout the life of the UPS to maintain
consistency across the cells and prolong the life of the UPS.
