Capacitor
failure
detection
If Capacitor failure detection is set to Enable, the power module (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. The
default value is Enable.
Capacitor
failure
detection
upper limit
(A)
The value range of Capacitor failure detection upper limit is 10–13 A.
When the inverter capacitor current exceeds the current specified by this
parameter, the power module determines that the inverter capacitor is
faulty and shuts down the inverter. The default value is 13 A.

Capacitor
failure
detection
lower limit
(A)
The value range of Capacitor failure detection lower limit is 0–2.5 A.
When the inverter capacitor current is lower than the current specified by
this parameter, the power module determines that the inverter capacitor is
faulty and shuts down the inverter. If Capacitor failure detection lower
limit is set to 0 A, the power module does not perform inverter capacitor
fault detection. The default value is 2.5 A.
Input cur.
limiting
Enable or disable input current limiting for the UPS to protect the D.G.
Input cur.
limiting ratio
(%)
Limit the input current to protect the D.G. The value can be 50%–200%.
The default value is 200%.

zero
If this parameter is set to Enable, the output current and load ratio will be
displayed as 0 in the case of zero load. If this parameter is set to Disable,
the output current and load ratio will not be displayed as 0 in the case of
