Description
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 to
accelerate the transfer and
prevent 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.
The optional negative
temperature coefficient
(NTC) resistor monitors the
ambient temperature near
batteries. It ensures that
batteries work reliably and
safely.
Specifies whether the BCB
trips when the UPS stops
supplying power and the
output power is off.
