Rack Mounting
If rack mounted units are installed in a closed or multi-unit rack assembly,
they may require further evaluation by Certification Agencies. The
following items must be considered:
1. The ambient temperature within the rack may be greater than room
temperature. 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 40 ºC.
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.
3. Reliable earthing of rack-mounted equipment should be maintained.
4. Thumbscrews should be tightened with a tool after both initial
installation and subsequent access.
