Installing the Power Extend Converter into a Distribution
Position
2.1
Important Safety Instructions
DANGER!
Adhere to the “Important Safety Instructions” starting on page v and those listed in the power system manual.
ALERT!
Only install the power extend converter into a -48 VDC distribution position. Non-repairable damage will occur if the
power extend converter is plugged into a +24 VDC distribution position.
NOTE!
The power extend converter can be inserted or removed with power applied (hot swappable) as long as the power
extend converter is inserted/removed with the enable/disable switch in the disabled position (see Figure 16 on page 24).
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.
2.2
Restrictions
Refer to the power extend converter instruction manual (UM565050) for wire sizing restrictions.
Refer to Table 7 and Table 8 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 and in specific distribution row positions. 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
to determine the necessity, quantity and 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 power system or
stand-alone distribution cabinet installed in an outside plant enclosure, leave the front door off the power system or stand-
alone distribution cabinet when complete with the installation.
