5.7 Connecting the Three-Phase AC Power Cable
For the SACU that supports the access of one MBUS route, connect the three-phase AC
power cable to the FU01 switch.
For the SACU that supports the access of two MBUS routes, connect the three-phase AC
power cable of the first route to the FU01 switch. Connect the three-phase AC power
cable of the second route to the FU02 switch.
This section describes how to connect the three-phase AC power cable for the SACU that
supports the access of two MBUS routes. For details about the single MBUS route
situation, refer to the way of connecting the first route of three-phase AC power cable.
Step 1
Prepare a cable.

Step 2
Connect the L1, L2, and L3 wires to the three-phase input switch.
Connect the L1-1, L2-1, and L3-1 wires from the FU01 switch respectively to ports A, B,
and C on the transformer station busbar 1 over a three-phase power switch.
Connect the L1-2, L2-2, and L3-2 wires from the FU02 switch respectively to ports A, B,
and C on the transformer station busbar 2 over a three-phase power switch.
Ensure that the L1, L2, and L3 wires are connected in correct phase sequence.
Step 3
Bind the cable.
