MX2000 Three-Phase Delta AC Power Distribution Module Description
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
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
C1 (bottom to
top). The second terminal block on the right is labeled
C2 (bottom to top). The PDMs are located at the rear of the chassis
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.
