8.2 Closing the Sunny Boy
1. Check wire routing to ensure that no wires can interfere with proper sealing of the lid and that
no pressure will be exerted on the connections when the lid is replaced.
2. Locate the six screws and lock washers you removed to take the lid off the Sunny Boy. Make
sure you have all six screws and lock washers, as all of this hardware is necessary to ensure
proper grounding and a weather-tight seal.
3. Check the seal on the inside of the lid to ensure it is undamaged and in correct position.
4. Carefully position the lid on the front of the Sunny Boy. Align the six holes in the lid correctly
with the six threaded holes in the case.
5. Hold the lid in place. Insert the six screws with lock washers through the holes in the lid into the
threaded holes of the enclosure. The toothing of the washers must face toward the lid.
6. Turn the screws finger-tight. Do not use power tools to tighten the screws.
DANGER
Electric shock due to touching the ungrounded lid.
Death or serious injury possible.
• When tightening the lid, ensure the proper grounding of the lid.
• The toothed washers ground the lid.
7. Tighten the screws clockwise with a torque of
53 in‑lbs. (6 Nm) torque. Refer to the order shown to
the right.
