Power, Ground, and Battery Cabling for Sites Equipped with
Customer–Supplied Site I/O Interface
DRAFT
SC300 1X BTS Hardware Installation, ATP, and FRU Procedures
JAN 2002
4-10
Objective
The objective of this procedure is to install the power, earth ground, and
battery cabling for one or more Microcell units at a site equipped with
customer–supplied Site I/O Interface.
Dangerous voltages, capable of causing death, are present
in this equipment. Use extreme caution when handling and
testing this equipment.
WARNING
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
Other Grounding
Considerations
This procedure covers only the grounding information for the cables that
attach to one or more MicroCell 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.
Motorola recommends that you use an oxide inhibitor such
as Burndy PENETROX or Ilsco DE–OX on all the
external ground connections on the unit and on the site I/O
interface for all outdoor installations. This includes the
ground connections on the mounting bracket, the Site I/O,
and the lugs on the customer–supplied site I/O interface.
NOTE
Power Requirements and
Configurations
The power requirements for each unit is: 120–240 VAC (7.5 amps min.)
or 20–30 VDC (20 amps min.) power input.
The AC Installation Box is required for all outdoor installations which
use the customer–supplied Site I/O interface.
The customer–supplied site I/O interface must be able to pass the
4kV/6kV transient impulse test (Motorola 12M09154A49 Sec. 3.5.3.2.1:
Impulse Surge, Test Condition A).
