1. The ambient within the rack may be greater than room ambient.
Installation should be such that the amount of air flow required for
safe operation is not compromised. The maximum temperature for the
equipment in this environment is 45°C. Consideration should be given to
the maximum rated ambient.
2. Installation should be such that a hazardous stability condition is not
achieved due to uneven loading.
