Note: Before installing the upper power distribution board, make sure that the lower power distribution board and enclosure air baffles have been installed into the enclosure (see Install the lower power distribution board and Install the enclosure air baffles).

  1. Install the upper power distribution board into the enclosure.
    1. Hold the two blue knobs to rotate the front of the upper power distribution board downward.
    2. Lower the upper power distribution board at an angle into the enclosure.
    3. Align the two openings in the middle of the upper power distribution board with the two power bus bars on the lower power distribution board. Then, slide the board into place while rotating the rear of the board downward to a horizontal position.
