AC Input Wire The manufacturer recommends the AC input wire specified in Table2.2 and
Table2.3. This must be permanently connected to an approved AC distribution box
with suitably rated over-current protection. If you require a special cord, contact the
manufacturer.

AC Wire Input
Connection
for 6000 W
See Figure 2.5, on page 42.
To connect the 6000W AC input wires:
1. Ensure that the AC input cord is de-energized, and that the power switch on the
front of the power supply is OFF.
2. Strip approximately 4 in. (10 cm) from the jacket of the AC wire. Strip 0.55 in.
(14 mm) at the end of each wire.
3. Undo the 2 screws for the AC wiring strain relief/cover on the rear panel.
Remove the cover.
4. Undo the strain relief screws. Insert the AC input cable through the strain relief
until the outer cable jacket is flush with the inside of the strain relief. Tighten the
strain relief cable clamp screws.
5. Insert the ground wire (green) 0.55 in. (14 mm) into the left-most terminal
location, and tighten securely. (The safety ground wire may alternatively be
connected to the chassis ground stud next to the terminal block, using a suitably
sized ring terminal).
