Description
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.
Enable or disable the memory
check function. If this parameter
