- Ensure adequate space between all vents and other objects (a minimum of 2" or 5 cm) to promote airflow and cooling and to keep the circuits from overheating.
- Avoid locations where ambient air reaches temperatures greater than 40° C.
- Avoid installing the connect module in a confined space.
- Avoid rack mounting the device.
- Avoid installing the connect module close to other devices that generate heat.
