lists the deployment rules for the HRE-454 List 5 and List 6 enclosures for HLU-431 and HLU-432
applications. These rules are shown as a function of the type of doubler that is used in HLU-431 circuits. The
HDU-409 mini-doubler requires less power and thus reduces the heat dissipated by the HLU-431 when the
doublers (listed in column four) are used.
