EPO
detection
Species whether to enable
EPO. EPO is performed only
when this parameter is set to
Enable and the EPO switch is
triggered.
When EPO detection is
changed from Disable to
Enable, check that the EPO
cable is connected correctly.

Paral. sys.
hibernate
When customer loads are
light, enable parallel
hibernation to alternate
modules in hibernation
mode, which can prolong
their service life and improve
system
eciency.

Intra-rack

module
startup
delay(s)
The two parameters enable
the UPS to control the
interval that each rack (or
module) transfers from
battery mode to normal
mode, which reduces the
impact on the generator or
power grid. In the case of
battery undervoltage, the
system automatically
shortens the delay for
transferring to normal mode
to 1/8 of the normal delay,
accelerating the transfer and
preventing battery
overdischarge. The start
delay of a module in a rack
varies depending on the rack
number and module number.
#1 module in rack 1 does not
have a start delay.
Depends on
the default
number of
power
modules. The
default value
is 2.0, 1.0, and
0.5 for 1–5, 6–
10, and 10–20
power
modules
respectively.

Batt. temp.
sensor
[B_TEMP]
(only for
lead-acid
batteries)
The optional negative
temperature coecient
(NTC) resistor monitors the
ambient temperature near
batteries. It ensures that
batteries work reliably and
safely.
