Interfaces
Input and output interfaces are laid at the back of the rectifier. For the interface layout of
the rectifier, see
. For a description of the pin definitions, refer to
The interfaces complete the electrical and signal connections between the rectifier and the
ZXDU68 B201 power system.

A rectifier communicates with other devices
through the interfaces. For example, a rectifier
transmits data to the CSU, and the CSU issues
commands to a rectifier.
