3.3.15.1.2 Configuring the PIU Hardware Version
You need to manually configure the PIU hardware version that should be
currently in use. The system periodically checks whether the configured and
actual hardware versions are identical. If there is a difference in the configured
and actual versions, an alarm is raised.
The hw_version parameter indicates the current supply capability of the PIU: 58A
(high-power PIU) or 35A.
