52 September 23, 1998 HLU-231 List 7E
The thermal loading limitations imposed when using the HLU-231 List 7E in Controlled Environmental Vaults
(CEV) or other enclosures are determined by applying the HLU-231 List 7E power parameters to the manufacturer
requirements for each specific housing.
The power consumption listed in Table 12 is the total power that the HLU-231 List 7E consumes or draws from
its -48 VDC shelf power source. This parameter is needed when the HLU-231 List 7E is located remote to its
serving CO. It determines the battery capacity required to maintain an 8-hour stand-by battery reserve for
emergency situations. It thus limits the maximum number of plugs per remote enclosure. Use this data to perform
this analysis on a case by case basis.
