AC Wye Power Shelf
The AC Wye power shelf arrives with a 5-wire Wye cord and an IEC 60309 plug rated 415 V/32 A, IP44,
3W+N+PE; it is 4 meters long. The power shelf has five corresponding terminations: three active (hot), one
neutral, and one ground. The ground lug and terminal block are located behind a removable cover on the rear
of the power shelf. The terminal block contains four terminations to attach the three active cable conductors
and one neutral cable conductor from the input power cord. The ground cable conductor from the input power
cord is attached to the ground lug.
The rear of the AC Wye power shelf with the rear cover removed is shown in this figure.
