Precis DSP Instruction Manual
Installation & Setup
Site Recommendations
When placing the enclosure, follow the recommendations and precautions in this section to reduce
potential installation and operation hazards. For complete specifications, see the tables on page 9.
Choose a clean, dust free, (preferably) air-conditioned location.
Avoid areas with direct sunlight, heat sources, or high levels of EMI
(Electromagnetic Interference).
Chassis Accessibility
Make sure the front and rear panels of the enclosure are accessible, so that you can monitor the LED
indicator. Leaving adequate clearance at the rear will also allow for easier cabling and service.
Power
The source’s electrical outlet should be installed near the router, easily accessible, and properly
grounded. Power should come from a building branch circuit. We recommend using a dedicated line for
the system’s power. Use a minimum breaker current rating of 15 A for 110 V or 30 A for 230 V.
To avoid an overload, note the power consumption rating of all the equipment connected to the circuit
breaker before applying power.
General Hazard Precautions
These recommendations address potential hazards that are common to all installations:
Elevated Operating Temperature
The maximum rated ambient temperature for Precis DSP enclosures is 95° F (35° C).
All equipment should be installed in an environment compatible with the manufacturer’s maximum
rated ambient temperature. 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
95° F (35° C) and follow the clearance recommendation below for adequate airflow.
Airflow Restriction
Precis DSP enclosures are designed to adequately dissipate the heat they produce under normal
operating conditions; however, this design is defeated when high-heat producing equipment is placed
directly above or below an enclosure.
Caution:
To prevent overheating, the system requires one empty rack unit above and below the
enclosure. Avoid placing high-heat producing equipment directly above or below the enclosure.
If such equipment must be installed above or below the Precis, more space (or a rack fan) may be
necessary. Verify that the openings on the sides of the enclosure are not blocked and do not have
restricted air flow.
Mechanical (Rack) Loading
When installing equipment in a rack, distribute the weight to avoid uneven mechanical loading.
