shows the three-phase wye AC PDM connections.

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 MX2020

chassis is not sensitive to phase rotation sequence—either CW or CCW will

operate correctly.
