Can I vertically mount my AP77XX Automatic Transfer Switch (ATS)?

Customers wish to vertically mount an AP77XX ATS

Product Line
AP77XX series Automatic Transfer Switches (all generations)

The AP77XX series ATS was designed to be installed horizontally. The effects of gravity on the internal components along with other concerns could prevent the product from operating as specified in other orientations; therefore mounting the ATS upside-down or vertically is unsupported. All units ship with brackets to allow the unit to be mounted horizontally.
