The objective of this procedure is to install the power, earth ground, and
battery cabling for one or more Microcell or Picocell units at a site
equipped with customer–supplied Site I/O Interface.
This procedure covers only the grounding information for the cables that
attach to one or more MicroCell or PicoCell units. Grounding
considerations beyond the ground cables that attach to the MicroCell are
summarized in Appendix A. Refer to Appendix A and the site
documentation for other grounding considerations.
The power requirements for the unit are: 120–240 VAC or 20–30 VDC
power input.
The AC Installation Box is required for all outdoor installations which
use the customer–supplied Site I/O interface.
The power and battery configurations for the MicroCell and PicoCell
units are:
AC power only (no battery)
AC power with short duration battery
DC power
SC 300 BTS Hardware Installation, ATP and FRU Procedures
WARNING
Dangerous voltages, capable of causing death, are present
in this equipment. Use extreme caution when handling and
testing this equipment.
NOTE
If you are installing the unit outdoors and are not using the
Primary Surge Suppressor, then you must connect AC
power with the AC Installation Box. The AC Installation
Box is included with the non–surge option.
NOTE
Neither the "+" or "–" terminal of the DC Input is
connected to the BTS ground. If a negative supply input is
provided, the "+" terminal of the DC input must be
connected to the Master Ground Plate (MGP). By
connecting the "+" terminal of the DC input to the MGP, a
negative supply system is created.
