(1.9 cm) of trim to the top, bottom, and sides of the panel backbox.
Panel electronics installation
To reduce possible damage to the panel’s electronics during backbox installation,
the electronics are packaged separately and must be installed in the panel
backbox. The electronics are shipped already mounted to a plastic backplane.
Note: Be sure that any possibility for construction damage and vandalism has
passed before installing the panel electronics.
