NOTE: The MX2020 systems configured for DC input power must use only
DC PDMs and DC PSMs. Systems configured for three-phase wye AC input
power must use only three-phase wye AC PDMs and AC PSMs. Systems
configured for three-phase delta AC input power must use only three-phase
delta AC PDMs and AC PSMs. AC and DC PSMs or PDMs must not be mixed
within a single system.
