Overview
Introduction
This section is a basic system overview of the architecture of Galaxy
Power Systems. The overview provides information about the
connections and physical considerations of the systems that must be
understood before the installation process begins.
The GPS individual cabinets may be connected together in two basic
architectures, distributed or centralized, to form systems. These two
architectures contain the same basic modules, but are arranged in
different cabinet configurations.
Single cabinet systems are considered neither distributed nor
centralized.
Bonding Network GPS systems are suitable for installation as part of a Common Bonding
Network (CBN) or an Isolated Bonding Network (IBN).
In this manual Battery Return grounds labeled "System (CO) ground"
are "Isolated DC return (DC-I)".
Installation as part of a Common Bonding Network (CBN) or an
Isolated Bonding Network (IBN) is determined by the point external to
the GPS system connected to GPS "System (CO) ground".
Facility GPS systems are suitable for installation in Network
Telecommunication Facilities and locations where NEC applies.
