System capacity (kVA)
Rated system capacity, equals to capacity of each power module multiplied by the
number of requisite power modules. The Module quantity mismatch alarm will be
generated if the setting is incorrect.
Power module capacity (kVA)
Rated power module capacity.
Requisite modules
Matches the rated system capacity.
Redundant modules
Set in accordance with load capacity and redundant requirements.
Working mode
The value can be Normal mode (default), Converter mode, Self-load mode, or ECO.
BSC mode
− The value can be Non-BSC mode (default) or BSC mode. The latter is set when the
system is a dual-bus system.
A dual-bus system consists of one master and one slave BSC system. You can
−
specify them during initial startup 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
properly connected and that BSC-related hardware is properly installed.
Parallel hibernation
When customer loads are light, set parallel hibernation to alternate modules in
hibernation, which can prolong their service life as well as improving the system
efficiency.
Module cycle hiber. period (d)
1 to 100 days can be set. 30 days is set by default.
Ambient temp. alarm thres. (° C)
An alarm is generated when the ambient temperature reaches the preset value.
Top outlet fan
If a top outlet fan is configured, check the fan running status after enabling this
parameter.
EOD restart
The UPS system transfers to battery mode when mains becomes abnormal. When
batteries reach the EOD threshold and the bypass is disabled, if EOD restart is enabled,
the UPS will restart as soon as the mains resumes.
If EOD restart is disabled, clear the alarm manually or enable the function to restart the
UPS.
EOD restart delay (min)
If EOD restart is set to Enable, the UPS starts working after EOD restart delay when
the mains recovers from an EOD power failure. The value range is 1–1440 min, and the
default value is 10 min.
Inverter async. alarm
Specifies whether the Inverter async. alarm is displayed when the inverter does not
track the bypass input. The normal power supply is not affected no matter whether you
set the parameter to Enable or Disable.
