6.1.1 Application Considerations
•
Do not select a mounting location on or near areas of high temperature components such as exhaust
systems and turbochargers.
•
The max ambient operating temperature of the controller is 185
°
F [85
°
C].
•
If the AFR is not mounted to a bulkhead ensure the mounting bracket is designed to withstand vibration
using vibration isolators, dampers, standoffs or multi-point mounting as needed.
•
The AFR has been tested to 7G’s @ 20 – 2000 Hz but excessive vibration can cause damage to
harnessing due to chafing and other factors.
•
Select a bracket material and geometry that supports the AFR securely without flexing due to
vibration.
•
Allow a minimum of 3 in. [76.2mm] in front of the controller to for harness connection and serviceability.
•
When selecting a mounting location ensure the AFR status indication LEDs are clearly visible for
diagnostic and troubleshooting purposes.
•
Mount the AFR so that the connectors are not facing upward in order to avoid possible water intrusion.
•
Select a flat surface or bracket for mounting the AFR to avoid flexing the controller packaging during
installation.
•
Mount the AFR in a location clear from walkways and steps so that the controller will not be damaged
during routine maintenance and operation.
•
Choose mounting hardware using the dimensions shown (i.e. Diameter < 0.202 in. [5.1mm]).
6.1.2 Installation Instructions
1. Clean the mounting area from any debris prior to mounting the AFR.
2. Mount the AFR to the selected location using a bracket or a direct to bulkhead mounting scheme using
the dimensions and application information provided.
•
If stand-offs or vibration isolators are required, make sure these are in place prior to proceeding.
3. Insert the mounting hardware selected into the four holes on the AFR.
•
Pre-drill and tap the locations as required prior to installation.
4. Using standard values, torque the selected mounting hardware down to a maximum of 3-6 lb. in. [0.34-
0.68 N•m] without applying excessive force to avoid damaging the mounting tabs or flexing the controller.
•
Ensure that each of the mounting bolts / screws is torqued evenly and gradually.
