Figure 164: Disconnecting the Power Cord from a Three-Phase Delta AC Power Distribution Module
To remove wires from the terminal block that serves three PSMs:
a. Remove the wire labeled L3 from the input terminal labeled C2.
b. Remove the wire labeled L2 from the input terminal labeled B2.
c. Remove the wire labeled L1 from the input terminal labeled A2.
d. Remove the grounding wire from the grounding point labeled GND.
NOTE: The three-phase delta AC PDM terminal blocks will be flipped depending on which
slot the PDM gets plugged into.
NOTE: The color of each AC power wire might vary. The MX2000 chassis is not sensitive
to phase rotation sequence—either clockwise or counterclockwise will operate correctly.
