Connection
for 12000 W
See Figure 2.6, on page 44.
To connect the 12000 W 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 2.75 in. (70 mm) from the jacket of the AC wire. Strip
0.55 in. (14 mm) at the end of each wire.
3. Remove the square AC input cover plate from the AC input bracket on the rear
panel, and a round knock-out from either the rear or right side of the bracket.
4. Insert the AC input cable through the knock-out and through the removable nut
from the strain relief until there is enough cord to attach the AC wires to the
terminal block (the nut must be inside the AC input bracket). Tighten the cable
clamp screws and the strain relief nut inside the AC input bracket until the AC
input wire is firmly held between the nut and the cable clamp screws.
5. Insert the ground wire (green) 0.55 in. (14 mm) into the left-most terminal
location, and tighten securely.
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. (14mm) into the terminal, and tighten the screw securely.
7. Reinstall the AC input cover plate.
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.
