3.3 Mounting
The Model 2120XL is a rack mountable unit intended for indoor
use only. Space and materials required for mounting are:
 8-3/4-inches (22.2 cm) of 19-inch rack space.
 Service access space behind and in front of the analyzer.
 Four mounting screws suited to the rack.
All operator controls are mounted on the control panel, which is
hinged on the left edge and doubles as the door that provides access to
components inside the controller module. The door latch is spring
loaded and will swing open when the button in the center of the latch
(upper right corner) is pressed all the way in with a narrow gauge tool
(less than 0.18 inch wide). Allow clearance for the door to open in a
90-degree arc of radius 7.125 inches. See Figure 3-1.
