Item Description Default Value Value Range
System
overvoltage
threshold (%)
When the mains voltage is
higher than the rated voltage
multiplied by the overvoltage
threshold, the system
generates an alarm.
120.0 105.0–125.0
System
undervoltage
threshold (%)
When the mains voltage is
lower than the rated voltage
multiplied by the
undervoltage threshold, the
system generates an alarm.
85.0 75.0–95.0
Overload
threshold (%)
Branch and mains current
overload alarm threshold.
When the branch current is
lower than the rated current
multiplied by the value of Br.
cur. shock protect (%) and
higher than the rated branch
current multiplied by the
value of Overload threshold
(%), the system generates a
branch overload alarm.
When the mains current is
higher than the rated mains
current multiplied by the
value of Overload threshold
(%), the system generates a
mains overload alarm.
100.0 100.0–120.0
Overcurrent
threshold (%)
Branch and mains
overcurrent threshold. When
the mains or branch current
is higher than the rated
mains or branch current
multiplied by the value of
Overcurrent threshold (%)
and lower than the rated
current multiplied by the
value of Overload threshold
(%), the system generates
an alarm.
80.0 80.0–100.0
