Item Description Default Value Value Range
Undercurrent
threshold (%)
Branch and mains
undercurrent threshold.
When the mains or branch
current is higher than the
rated mains or branch
current multiplied by the
value of Undercurrent
threshold (%) and lower
than the rated current
multiplied by the value of
Overcurrent threshold (%),
the system generates an
alarm.
60.0 30.0–80.0
Three-phase
load
imbalance
(%)
Mains three-phase current
imbalance alarm threshold.
When the dierence between
the highest and lowest mains
three-phase currents is
higher than the alarm
threshold, the system
generates an alarm.
25.0 5.0–50.0
Mains current
exceeding
lower
threshold
If this parameter is set to
Enable, the system generates
an alarm when the mains
current is below the lower
current threshold. If this
parameter is set to Disable,
the system does not generate
the alarm under any
condition.
Enable Disable,
Enable
Mains current
exceeding
higher
threshold
If this parameter is set to
Enable, the system generates
an alarm when the mains
current exceeds the higher
current threshold. If this
parameter is set to Disable,
the system does not generate
the alarm under any
condition.
Enable Disable,
Enable
Mains three-
phase current
imbalance
If this parameter is set to
Enable, the system generates
an alarm when the mains
three-phase current is
imbalanced. If this parameter
is set to Disable, the system
does not generate the alarm
under any condition.
Enable Disable,
