Site wiring
problem
Site Fault detection is
supported on LV & HV
models anytime there is
a Neutral connection
AND it is an LV model
or has been manually
enabled on the HV
model.
Alarm triggers when the
difference between
ground and neutral
voltage is >= 25Vrms.
Beeping
Check the site wiring.
Output
overload level
L2
Load greater than level
2 threshold and less
than level 3 threshold.
Alarm clears when the
load drops below 5% of
the set point.
Beeping
Contact Dell.
Output
overload level
L3
Load greater than level
3 threshold.
Alarm clears when the
load drops below 5% of
the set point.
Beeping
Contact Dell.
Battery DC
over voltage
Battery voltage levels
have exceeded the
maximum allowable
limits.
Beeping
Contact Dell.
Inverter AC
over voltage
UPS has detected
abnormally high
inverter output voltage
levels.
Beeping
Contact Dell.
Inverter AC
under voltage
UPS has detected
abnormally low inverter
output voltage levels
Beeping
Contact Dell.
