ECO voltage
range
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.

BSC mode

Set this parameter to
Standard BSC for a dual-bus
system.

After setting this parameter to
Standard BSC, you need to
set the two UPS systems in
the dual-bus system to BSC
master system and BSC
slave system respectively in
the BSC master/slave system
setting. (The two UPS
systems cannot be BSC
master systems or BSC slave
systems at the same time. If
you need to change the
settings in the future, perform
operations 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.
Non-BSC
Non-BSC,
