Figure 139: Connecting Power to a Three-Phase Wye AC Power Distribution

Module

NOTE: The three-phase wye 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 MX2020 chassis
is not sensitive to phase rotation sequence—either CW or CCW will operate
correctly.
To insert wires into the terminal block that serves three PSMs:
a. Insert the grounding wire into the grounding point labeled
b. Insert the wire into the input terminal labeled
c. Insert the wire into the input terminal labeled
d. Insert the wire into the input terminal labeled
e. Insert the wire into the input terminal labeled
NOTE: The terminal connections have either slotted screws or hex screws.
Use a 1/4-in. slotted screwdriver for the slotted screws. Use a 5/32-in.
(4-mm) Allen wrench for the 5/16-in. hex screws.
Verify that the power cord wire connections are correct.
