Configuring the Freedom SW using the SCP
Equalization Procedure
To start equalizing the batteries, do one of the following:
• Apply AC voltage and ensure that the inverter/charger transfers
AC and starts charging.
• On the Xanbus Setup menu, highlight Equalize and select
Enable.
The unit will proceed and execute a complete bulk and
absorption charge before transitioning to equalize.
IMPORTANT: The inverter/charger will not perform
equalization if AC is not present, the charger is disabled, or the
selected battery type does not support equalization. If any of
these cases happen, a warning is issued
If the Freedom SW will not perform the equalization, see“Detected
Warning Types and Behavior” on page 73.
EXPLOSION HAZARD
Equalize charge flooded or vented batteries only. Hydrogen and oxygen
gases are produced when batteries are equalize charged. Provide adequate
ventilation and remove all sources of ignition to prevent explosion.
Failure to follow these instructions can result in death or serious
injury.
IMPORTANT:
In a system where more than one device is capable of
equalizing batteries (such as stacked Freedom SWs), there is no system-wide
equalization command for all devices. To equalize with two devices, each
would have to be enabled individually. Alternatively, equalization can be
performed using only one device. During the equalization process, one
device applies the equalization charge while the other devices continue to
operate in synchronized charge mode, typically in float (three-stage
charging) or no-float (two-stage charging).
