AC Section
The AC section (ACS) is positioned at the input side of the power supply unit (PSU), to
protect the system from electromagnetic interference (EMI).
There are two types of ACS, ACS for M8000 and ACS for M9000. Both single-phase AC
and three-phase AC types are available for both types. ACS consists of a terminal strip for
power input, a main line switch, and so on. Among the ACS, ACS_D is a unit for supplying
the internal current to the three-phase power feed cabinet, which doesn't have a main line
switch and the external connection.
