Abstract:
A method for installing mail-handling towers of various heights at a mail-handling site, said method comprising the steps of:prior to physical installation of any one of said towers at its intended tower location within said site, selecting a location at which an interface box can be installed, including the step of determining a support location which is within a particular radius from a particular location near the upper end of the particular one of said towers, having a particular height, to be installed at said tower location within said site;procuring an interface box including at least two power terminals associated with a NEMA configuration female connector having a particular pin configuration, and also including at least two power terminals which are not in a NEMA configuration connector, and further having electrical interconnections between at least two of said NEMA pins and corresponding ones of said non-NEMA terminals;no later than the time of physical installation of said particular one of said towers at said tower location within said site, physically installing said interface box at said support location;no later than the time of physical installation of said particular one of said towers at said tower location within said site, making conventional electrical connections between a source of electrical power and said non-NEMA power terminals of said interface box;no later than concurrently with completion of said physical installation of said particular one of said towers at said tower location within said site, testing the power available at said pins of said NEMA configuration female connector to verify conformance with a standard;installing at said tower location one of said towers having said particular height, and also having a flexible power cord terminated at a NEMA configuration male connector and having a pin configuration mating with that of said NEMA configuration female connector, which power cord is affixed to said particular location near the upper end of said one of said towers, said power cord having a free end capable of being extended from said particular location near said upper end of said one of said towers by an amount which is greater than said radius; andmaking a connection between said NEMA configuration male and female connectors.
