board (Figure 2-5).
5. Loosen and remove the two nuts securing the two hinge/grounding straps that
connect the front panel to the rear housing.
6. For the AC model: Cut the nylon wire tie securing the ferrite core on the AC
wires to the plastic adhesive pad.
7. Note how the two AC power wires are looped through the ferrite core and then
remove the ferrite core from the two wires.
8. Unscrew the nut that secures the green/yellow ground wire to the enclosure
and remove the wire and loop terminal from the threaded stud.
9. Loosen and remove the cable gland and AC power cable from the rear of the
enclosure.
