Description
Specifies whether the UPS works in single
mode or parallel mode.
Matches the system capacity.
Set this parameter according to load capacity
and redundancy requirements.
UPS working mode.
In ECO mode, when the difference between
the bypass voltage and the rated voltage is
greater than this value, the system determines
that the ECO voltage is abnormal and
transfers to normal mode.
 If the system is a dual-bus system that
consists of Huawei UPSs, set this
parameter to Standard BSC mode.

A dual-bus system consists of the master
and slave BSC systems. You can specify
the master and slave BSC systems (one
master and one slave) and change the
settings under the guidance of
maintenance engineers. Set the master and
slave BSC systems to master and slave
BSC modes respectively.

Ensure that the BSC signal cable between
the master and slave BSC systems is
