Instrument Installation
Panel Location and Mounting
The diagram below shows the outside dimensions of the front bezel of the EMS-D120. Note that
the instrument and tray extend about 4.5” behind the panel, and the supplied harness extends
three inches more. Use the dimensions (in inches) found on the diagram to plan for the space
required by the instrument. Take the following considerations into account when selecting a
mounting location for the EMS-D120.
Avoid placing the instrument near heater vents or any source of extremely hot or cold air. Keep
in mind that the air surrounding the EMS-D120 during operation may be no warmer than 50
C.
To mount the EMS-D120, you must make a rectangular cutout in your panel. Ensure that the
dimensions of the cutout are: 6.780” wide and 4.750” tall. Place the D100-series mounting tray
behind the cutout. Secure it to your panel in whatever way you desire. Riveting it to the panel is
ideal, but drilling holes for mounting screws and nuts will work as well. You may cut off 2
horizontal or vertical tabs from the mounting tray to minimize the space taken up behind the
panel. Upon securing the mounting rack to the back of your panel, slide the EMS-D120 into it.
Use the included 7/64” Allen wrench to secure the mounting screw (at the bottom left of the
front bezel) into mounting rack. At your discretion, you can also screw a #6-32 screw into the
back of the mounting rack on the opposite side. This screw should penetrate into the instrument
no further than ¼”.
