5. Unscrew the external cable clamp that secures the power cable in position at the rear
of power plug.
6. Loosen the two retaining screws on the front of the plug module; pull and separate
the two housing halves away from each other to expose the terminal screws.
7. Remove the brown wire from the pin marked “L/+” by loosening the slotted screw that
secures the wire to the plug pin.
8. Remove the blue wire from the pin marked “BLUE” by loosening the slotted screw
that secures the wire to the plug pin.
9. Remove the green/yellow wire, “Ground”, from the threaded screw by loosening the
slotted screw that secures the wire to the plug pin.
10. Loosen, but do not remove, the two internal cable clamp screws that secure the
power cable.
11. Pull the cable assembly leads out from the L/+, BLUE, and Ground terminal access
holes and remove them from the plug module.
Installing the 7K25 AC Power Plug
Note: Use specified AC power plugs only.
1. Remove the new 7K25 plug assembly from its packaging, and loosen the two
assembly screws, located on the front of the plug.
2. Remove the plug module from the housing.
3. Loosen, but do not remove, the two internal cable clamp screws that secure the cable
clamp to the housing.
4. Loosen and remove the rear external cable clamp (with the black compression
washer and flat washer).
5. Route the AC power cable wires and a portion of cable through the external clamp,
flat washer, compression washer, and connection housing rear opening.
6. Strip the ends of the power cable wires in accordance with the manufacturer’s
instruction sheet shipped with the plug.
7. Verify the color-coded wire use before connecting the wires to the plug module
terminals. Ensure that the correct color-coded wire is being connected to the Line
(“L/+”), Neutral (“BLUE”), and Ground terminals on the plug module.
8. Connect the stripped wire ends to the terminals of the plug module as follows:
– Attach the green/yellow wire to the threaded screw (Ground) and tighten the
slotted screw to secure the wire; torque the screw to 18 pounds/inch.
– Attach the brown wire to the pin marked L/+ (Line) and tighten the slotted screw to
secure the wire to the pin; torque the screw to 18 pounds/inch.
– Attach the blue wire to the pin marked BLUE (Neutral) and tighten the slotted
screw to secure the wire to the pin; torque the screw to 18 pounds/inch.
9. Tighten the two internal cable clamp screws to secure the cable to the plug assembly;
torque the cable clamp screws to 10 pounds/inch. Perform the following electrical
tests:
– Use an Ohmmeter to make continuity checks of wiring to verify that the correct
phasing and grounding connections have been made.
