Placing the Enclosure(s)
This chapter covers site recommendations and provides a step-by-step
procedure for installing a Modula Distribution Matrix in a rack.
2.1 Site Recommendations
When placing the enclosure, site recommendations should be considered
to reduce potential hazards in regard to environment, chassis
accessibility, cooling and airflow, and power.
To make control panel operations easier, mount the enclosure with the
control panel attached in the rack at eye level–the optimum viewing
angle for the LCD screen is 15°. Install a multi-enclosure system with all
the enclosures linked so control information can travel between them.
General Hazard Precautions
The recommendations listed address potential hazards that are considered
common to most rack installations:
Elevated Operating Ambient Temperature
Consideration should be given to installing the equipment in an
environment compatible with the manufacturer’s maximum rated
ambient temperature. This precaution is advised 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 the maximum recommended ambient temperature of
104°F (40°C). To prevent airflow restriction, allow at least 3 inches
(7.6 cm) of clearance around the enclosure openings for proper airflow.
