Description
These 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 to
accelerate the transfer and
prevent battery
overdischarge. Intra-rack
power module start delay
(s) can be set to a value
ranging from 0.5 to 120.
Inter-rack power module
start delay (s) can be set to
a value ranging from 2 to
120. The preset value of
Inter-rack power module
start delay (s) is 5.0. 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.
If the maintenance bypass
unit is configured, set this
parameter to Enable.
N/A
Indicates whether the BCB
trips when the system stops
supplying power and the
output power is off.
