AC Delta Power Shelf
The rear of the AC Delta power shelf with the rear cover removed is shown in
. For more information on AC Wye power shelf, see
section.
When removing AC wiring from the fixed configuration power shelf, be sure to remove the ground cable
conductor last.
Note
Steps
To disconnect the AC power cord from the fixed configuration AC power shelf, perform the following:
SUMMARY STEPS
1.
Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection
sockets on the front (PLIM) side of the chassis or a bare metal surface on the chassis.
2.
For AC Delta and AC Wye, disconnect the three active cable conductors by loosening the screw on the
left side of the terminal block for each cable conductor and removing the cable conductor.
3.
For AC Wye only, disconnect the neutral cable conductor by backing out the left side terminal block
screw and removing the cable conductor. White is usually neutral.
4.
Remove the M6 nut from the ground connection (green is typically the ground cable conductor) and
remove the ground cable conductor.
