Shut off machine power by unplugging the unit.
Open the two front door latches, loosen the two captive
screws in the corners of the housing opposite the
hinges, then open the NEMA box. Place an object
underneath the door once open to help support it
during this procedure.
Remove the orange ethernet cable on the left by
disconnecting both ends, then removing it. Set aside for
re-use. Remove the power cable connector on the right
by loosening the captive screw on each end of the green
connector, then unplugging the connector. Disconnect
the ground wire by loosening the ground wire retaining
screw, then carefully removing the ground wire. Refer to
Figures 1.A & 1.B.
Remove and retain the four mounting screws from the
four corners of the protective front cover, then slowly lift
the front cover, carefully flip it over, then set it down,
upside down, to rest on the inside of the enclosure door.
Be careful as there are still many wires connected
between the enclosure and the front cover and there
isn’t a lot of slack. Note that the two upper front cover
mounting screws are located in plain sight in the top
corners of the front cover, while the two lower front cover
corner mounting screws are located down in the front
“well” of the unit. Use a long-handled screwdriver to
remove them.
