Description
If this parameter is set to Enable,
the output current and output
load ratio are displayed as < 3%
in the case of no load. If this
parameter is set to Disable, the
output current and output load
ratio are not displayed as 0 in the
case of no load.
If this parameter is set to Enable,
the current at no load will be
calibrated once automatically.
This function can be used only
when the UPS carries no load.
Set this parameter based on the
output interruption time
acceptable to loads.
Cross currents occur during the
transfer between bypass mode
and inverter mode, which
impacts the system. This
parameter specifies the number
of transfers between bypass
mode and inverter mode within 1
hour, which ensures system
security.
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 maintenance page.
Specifies whether an Inverter
asynchronous alarm can be
displayed on the LCD when the
inverter cannot track the bypass
frequency change. Normal power
supply is not affected no matter
whether this parameter is set to
Enable or Disable.
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
