AC Wire Input Connection
See Figure 2.2, on page 18.
To connect the 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 6.25 in. (160 mm) 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
1
. (The safety ground wire may alternatively be
connected to the chassis ground stud next to the terminal block, using a suitably
sized ring terminal).
6. Route the AC wires to the input terminal block by connecting the red, black, and
white wires to the remaining 3 cable clamp connectors. There is no set order for
connecting the wires. Any of the 3-phase wires can be connected to any of the 3
line input connectors. To connect each wire, loosen the terminal screw, insert the
stripped wire 0.55 in. (14 mm) into the terminal, and tighten the screw securely
1
.
7. Reinstall the AC input strain relief/cover, routing wires inside the cover to
prevent pinching.
8. Connect the free end of the cable to the AC source, checking that the voltage is
within the approved input range for the supply.
9. Energize the AC input.
It is now safe to turn the power supply on.
1. Torque maximum 2 Nm/16 lb. in.
