Description
An alarm is generated when the ambient
temperature reaches or exceeds the
threshold specified by this parameter.
An alarm is generated when the ambient
temperature is lower than the threshold
specified by this parameter.
Indicates whether to enable emergency
power-off (EPO). EPO is performed only
when this parameter is enabled and the
EPO switch is triggered.
When EPO detection is changed from
Disable to Enable, check that the EPO
cable is connected correctly.
If this parameter is set to Enable, the
UPS detects the bus capacitor lifespan.
When customer loads are light, enable
parallel hibernation to alternate modules
in hibernation mode, which can prolong
their service life and improve the system
efficiency.
Indicates the rotation interval of
modules in hibernation mode. The
default value is 30, which means that
the hibernating module is rotated every
30 days.
Indicates whether ECO bypass is allowed
to supply power in D.G. mode. When the
D.G. is connected to the dry contact
signal GEN:
● If this parameter is set to Enable, the
system can enter ECO bypass mode
when the D.G. supplies power to the
bypass and the ECO function is
enabled.
● If this parameter is set to Disable, the
system is not allowed to enter ECO
mode when the D.G. supplies power
to the bypass.
