Installation Recommendations
When placing the enclosure, follow the recommendations and precautions in this
section to reduce potential installation and operation hazards. The Precis
LT
ships with
four rubber feet and two rack ears. Depending on the installation, you may either
surface mount the enclosure or mount it in a rack.
Environmental Recommendations
q
Choose a clean, dust free (preferably air-conditioned) location
q
Avoid areas with direct sunlight, heat sources, or high levels of EMI
(Electro-Magnetic Interference)
General Hazard Precautions
These recommendations address potential hazards that are common to all
installations:
Elevated Operating Temperature
The maximum rated ambient temperature is 110° F (43° C).
All equipment should be installed in an environment compatible with the
manufacturer’s maximum rated ambient temperature. This is important because in a
closed or multi-unit rack assembly, the operating ambient temperature of the rack
environment may be greater than the ambient room temperature.
Caution: To protect the equipment from overheating, do not operate in an area that
exceeds 110° F (43° C) and follow the clearance recommendation in the “Airflow
Restriction” paragraph below.
Airflow Restriction
To prevent airflow restriction, we recommend 3 inches (7.6 cm) of clearance around
the enclosure openings. At a minimum, leave at least one empty rack unit above and
below the enclosure. Avoid placing high heat-producing equipment directly above or
below the enclosure. Precis
LT
enclosures are designed to adequately dissipate the
