MX2000 Three-Phase Delta AC Power Distribution Module Description
Each three-phase delta AC power distribution module (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 serves six power supply modules (PSMs) and the second terminal block serves three PSMs. The terminal block on the left is labeled A1, B1, and C1 (bottom to top). The second terminal block on the right is labeled A2, B2, and C2 (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 delta AC PDM.
The three-phase delta AC PDM terminal blocks will be flipped depending on which slot the PDM gets plugged into.
Figure 2 shows the three-phase delta AC PDM connections.
The three-phase delta 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 clockwise or counter-clockwise will operate correctly.
