Safety Instructions for Rack Mount Installations
The instructions below (or similar) are intended for LIB-4xxx rackmount installation
environments:
1. Elevated Operating Ambient: if installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment may exceed room ambient. Install
the equipment in an environment compatible with the maximum ambient temperature (Tma)
specified.
2. Reduced Air Flow: install the equipment in a rack so that the amount of air flow required
for safe operation is not compromised.
3. Mechanical Loading: Mount the equipment in the rack so that a hazardous condition
does not occur due to uneven mechanical loading (weight distribution/rack balance).
4. Circuit Overloading: give consideration to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on overcurrent protection
and supply wiring. Consider all equipment nameplate ratings when addressing this
concern.
5. Reliable Earthing: maintain reliable earthing of rack-mounted equipment; pay particular
attention to supply connections other than direct connections to the branch circuit (e.g.,
use of power strips).
