Mount each module panel to the front frame.
• Mount the panels from behind the front frame.
• Insert the holders into the slots on both sides.
(With the GT-4F, mount the module panels so that they catch on the tabs in
order from top to bottom.)

et.

While using the mounting gauge to make adjustments, tighten the screws.
(A mounting gauge is included with the GF-2B, GF-3B, and GT-4B built-in
back box.)
