Select an area with sufficient ventilation for the mounting of the black box in order to prevent the module from
overheating. You may mount the black box in a horizontal or vertical position. If the black box is mounted in a
vertical position, do not mount the module with the harness exit points directly facing up to prevent water collecting
in these areas.

Please refer to the diagram below for the mounting screw hole positions. Always use the shortest length of screw
possible.

During installation, use the 4 rubber mounting stoppers (included in the package) for the bottom of the module. This
provides clearance from surface moisture and provides sufficient ventilation for the heat sink.
