DOUBLER ENCLOSURE CAPACITIES WITH FULL SOLAR LOAD

The EDU-409 List 1 can be housed in a variety of outdoor enclosures manufactured by ADC and other vendors. The number of doublers used in any of the enclosures depends on the maximum outside ambient temperature. The doubler capacities for several of these standard enclosures is listed in Table 5 on page 13 and Table 6 on page 14. The capacities listed in Table 6 (for both indoor and outdoor enclosures) are based on a maximum outside temperature of +46.1 °C (+115 °F). Consult ADC for the latest deployment rules when using the enclosures at ambient temperatures above +46.1 °C.

These requirements comply with Bellcore standards, which require HDSL equipment place in outdoor cabinets to operate in a temperature, outside the housing, of -40 °F (-40 °C) with no solar load and +115 °F (+46.1 °C) with a maximum solar load and maximum power dissipation.

Full solar load is equal to maximum sunlight exposure as defined in Bellcore’s Technical Advisory TR-TSY-000057.
