The line-disconnect switch must be in the OFF position before you

until all installation steps are complete. In the United States, use a "lock
out/tag out" procedure until installation is complete. In other countries,
follow the appropriate national and local safety procedures. Refer to the
Safety and Compliance Manual (80669C) for more safety

The distance of the receptacle from the main box also can have an effect on size requirements for the main power cord. For information about the codes in your location and the requirements for your site, speak with a licensed electrician.
