SDB680 – INSTALLATION GUIDE

ENVIRONMENTAL CONDITIONS

O T
PERATING EMPERATURE
For the 50 W SDB680 Base Stations, the operating temperature range is: −30 °C to +60 °C (−22 °F to +140
°F) ambient temperature.
The storage temperature range is −40 °C to +80 °C (−40 °F to +176 °F).
Ambient temperature is defined as the temperature of the air at the intake to the cooling fans.
H
UMIDITY
The humidity should not exceed 95% relative humidity non-condensing through the specified operating
temperature range.
D D
UST AND IRT
The SDB680 Base Station has an Ingress Protection rating of IP30, i.e. it provides protection against access
to hazardous parts and the ingress of solid foreign objects >12.5 mm in size.
V
ENTILATION
The SDB680 Base Station uses forced air cooling to maintain internal temperatures and adequate cooling
airflow is critical to the performance of the base station. Whether wall mounted or rack mounted, always
ensure that there is adequate ventilation around the base station. The ambient temperature must be kept
within the specified range and it is strongly recommended that the cooling airflow is not restricted.
For the SDB680 Base Station, the essential cooling airflow (recommended <40 °C) enters through one side
of the unit and the hot exhaust air exits at the rear of the unit. For optimal thermal performance, heated air
that has passed through the base station must not be allowed to re-enter the air intakes of the unit.
2
At least 72 cm of ventilation MUST be provided for each base station at the inlet AND at the outlet.
In order to allow enough airflow through a rack mounted base station, it is recommended that:
A minimum distance of 5 cm clearance to any obstruction at the front of the unit.
•
A minimum distance of 10 cm clearance to any obstruction at the rear of the unit.
•
An open area of at least 50 cm
•
fans of each unit; e.g. ten 6 x 85 mm slots will allow the recommended airflow.
An open area of at least 50 cm
•
top of the rack.
A 2U gap at the top of the rack.
•
Note.
The ventilation openings must be unrestricted. If the openings are covered with a filter or grille, the
open area must be increased in order to provide the same airflow as unrestricted openings.
If the SDB680 Base Station is installed in a rack or cabinet with other equipment that has different
ventilation requirements, it is recommended that the SDB680 be positioned below this equipment.
If multiple bases are fitted in a rack, auxiliary extractor fans may be required to ensure that adequate cooling
is provided.
If any other configuration is employed, the performance of the system will depend on how closely you
comply with the airflow requirements described above.
