WARNING! The power extend converter and front mounting bracket becomes very hot during power
extend converter operation at heavy load. Wear heat resistant gloves or allow the power extend
converter to cool down before removing.
Restrictions
Refer to the power extend converter instruction manual (UM565050) for wire sizing restrictions.
Refer to Table 4 for spacing and power restrictions. This table shows how many converters can be placed side
by side before skipping a single space at certain average power levels. These power levels pertain to the
average output power (busy hour average power) drawn by the load including any power loss in the cable. The
peak power available from each unit remains at 1000 watts regardless of spacing or location. Use the calculator
tool that can be obtained at

spacing requirement of the Power Extend Converter based on the RRU type (or peak load), use application
(host power system), trunk and jumper cable size and length, minimum source voltage and minimum RRU
operating voltage.
NOTE!
When installing a power extend converter mounting bracket kit covered by these instructions
onto a stand-alone distribution cabinet installed in an outside plant enclosure, leave the front door off
the stand-alone distribution cabinet when complete with the installation.
