MX2000 Three-Phase Wye AC Power Distribution Module Description

 

Each three-phase wye AC PDM weighs approximately 12 lb (5.44 kg). A metal wiring compartment contains two AC terminal blocks and ground labeled GND. One AC terminal block consists of three input terminals that serve six PSMs and the second terminal block serves three PSMs. The terminal block on the far left is labeled A1, B1, C1, and N1 (bottom to top). The second terminal block is labeled A2, B2, C2, and N2 (bottom to top). The PDMs are located at the rear of the chassis in slots PDM0/Input0 through PDM1/Input1, (bottom to top). LEDs provide the status of the PDM. Figure 1 shows the three-phase wye AC PDM.

Note

The three-phase wye AC PDM terminal blocks will be flipped depending on which slot the PDM gets plugged into.

Caution

The three-phase wye AC PDM must be installed and secured in the chassis before connecting the power input cables. If the PDM must be removed, both input power cables must be uninstalled and removed from the PDM before the PDM can be removed from the chassis. The MX Series chassis is not sensitive to phase rotation sequence—either CW or CCW will operate correctly.
