Description
Specifies whether the UPS works
in single mode or parallel mode.
Sets this parameter based on the
system capacity.
Sets this parameter based on load
capacity and redundancy
requirements.
Set the UPS working mode.
In ECO mode, when the
difference between the bypass
voltage and the rated voltage is
greater than the specified value,
the system determines that the
ECO voltage is abnormal and
transfers to mains inverter mode.
 If the system is a dual-bus
system that consists of
Huawei UPSs, set this
parameter to Standard BSC
mode.
 After setting BSC mode to
Standard BSC mode, on the
BSC Master/Slave System
screen, set the two UPS
systems in the dual-bus
system to BSC master
system and BSC slave system
(one master and one slave)
and change the settings under
the guidance of maintenance
engineers.
NOTE
Ensure that the BSC signal cable
between the BSC master and slave
systems is properly connected and
that BSC-related hardware is
properly installed.
Sets this parameter based on the
altitude of the place where the
rack is used.
Enable this parameter if a top
outlet fan is configured. You can
