For the SACU that houses one potential induced degradation (PID) module, connect the
three-phase AC power cable to the FU01 switch, and the functional earthing (FE) cable to
FE01 on the FE bar.
For the SACU that houses two PID modules, connect the three-phase AC power cable of
the first route to the FU01 switch, and the corresponding FE cable to FE01 on the FE bar.
Connect the three-phase AC power cable of the second route to the FU02 switch, and the
corresponding FE cable to FE02 on the FE bar.
Do not reversely connect the cables to FE01 and FE02.
This document describes how to connect three-phase AC power cables for the SACU that
houses two PID modules. For details about how to connect a three-phase AC power cable
for the SACU that houses one PID module, refer to the way of connecting the first route of
the three-phase AC power cable.
