Specifies whether the
Inverter async.
alarm is displayed when the inverter does not
track the bypass input. The normal power supply is not affected regardless of whether the
parameter is
Enable
or
Disable
.
Bus overvoltage recovery
Specifies whether to automatically clear the alarm and restart the power module when
the rectifier or inverter shuts down due to a bus overvoltage alarm. If
Bus overvoltage
recovery
is set to
Enable
, the bus overvoltage alarm is automatically cleared, and the
rectifier and inverter automatically start when the bus voltage recovers (less than 420 V)
within
Bus overvolt. recovery time
. When
Bus overvoltage recovery
is set to
Disable
,
the bus overvoltage alarm cannot be automatically cleared, and the rectifier and inverter
cannot automatically start. The default value is
Enable
.
Bus overvolt. recovery time
If
Bus overvoltage recovery
is set to
Enable
, the bus overvoltage alarm is automatically
cleared, and the rectifier and inverter automatically start when the bus voltage recovers
(less than 420 V) within
Bus overvolt. recovery time
. The default value is
5s
.
Capacitor failure detection
By default, it is set to
Disable
.
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 display with no load output
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 zero load.
Current equal. detection
Monitors the current differences between racks or modules. If this parameter is set to
Enable
, the
Mod. Cur. Eql. Data
can be viewed on the running information screen. This
parameter is set to
Disable
by default.
Bus Capa. Life
If
Bus Capa. Life
is set to
Enable
, the UPS detects the bus capacitor lifespan.
Altitude (m)
Set this parameter based on the altitude of the place where the rack is used. The default
value is less than or equal to 1000.
ModbusTCP Encryption
If Modbus TCP is used for communication, communication links implement encryption
based on the selected encryption mode or do not implement encryption.
Air filter maintenance period (d)
Set this parameter to the rack dustproof maintenance period. When it is set to 0, there is
no reminder.
BCB trips if UPS stops power supply
This parameter is set to
Enable
by default.
Input Parameter Settings
Set input parameters, as shown in
