In some applications, it is necessary for the Controller to be mounted in a non-
standard orientation. To accommodate such installations and ensure that the
display will appear at the correct angle for viewing, the PCB Assembly can be
rotated inside the Controller.
Figure 10: Non-standard Orientation
Note: Ensure orientation allows for connections and excess wire within Controller
Housing.
WARNING: See Appendix D, "Electrostatic Sensitive Device (ESD)", on
page 13 for handling instructions of electronic components.
