detection
(power unit) performs inverter
capacitor fault detection based on
the settings of
Capacitor failure
detection upper limit
and
Capacitor failure detection
lower limit
. If the power module
determines that the inverter
capacitor is faulty, it shuts down
the inverter to prevent the fault
from expanding.

cur. eql. detect
Enable or disable the light load
bypass current imbalance alarm.
If this parameter is set to
Enable
,
the load is light (less than 30%
load), and the load rate of a
certain rack is less than 10%, the
system will generate a bypass
current imbalance alarm and
cannot enter the ECO mode. If
this parameter is set to
Disable
,
the preceding detection is not
performed. Whether the bypass
current is imbalanced does not
affect the ECO bypass mode.

Battery Settings
Battery parameter settings impact battery maintenance, battery lifespan, and UPS discharge
time. When you set battery parameters, note the following:
Retain default settings for
Chg. cur. limiting coef.
and
Cell float voltage
. Only
professional maintenance personnel are allowed to change the settings.
When you set parameters, ensure the following:
