Connecting the Three-Phase AC Power Cable
- For the SACU that houses one PID module, connect the three-phase AC power cable to the FU01 switch, and the FE wire 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 wire 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 wire to FE02 on the FE bar.
- This section describes how to connect three-phase AC power cables for the SACU with two PID modules. For details about the single PID module situation, refer to the way of connecting the first route of three-phase AC power cable.
- Prepare a cable.Figure 5-16 Length for cable stripping
- Crimp an OT terminal.
- Connect the L1, L2, and L3 wires to the three-phase input switch, and the FE wire to the FE bar.
- 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.
- Connect the FE wire for the PID module to the ground bar in the transformer station.
- Ensure that the L1, L2, and L3 wires are connected in correct phase sequence.
- Do not mix up the wire to the FE01 port with the wire to the FE02 port.
- Bind the cable.Figure 5-17 Connecting a cable
