Equipment Applications; Lorain Cip Power Systems; Lorain Cip Access Power Systems - Emerson Lorain CIP 4890 AP6C55CB User Manual

The system meets FCC Class B requirements for EMI, as well as NEBS
Level 3 requirements for telecom equipment, including seismic zone 4, when
mounted in equipment that does so (rack, cabinet, enclosure, etc.).
The controller used in the Lorain CIP Access power shelf is the AP7C56BA
System Manager CIP. It provides a variety of monitoring, alarm and control
features normally found on power systems' controllers, such as high and low
voltage alarms, battery on discharge alarm, fuse and circuit breaker alarms,
rectifier failure alarms, boost charge, low voltage disconnect (to activate the
optional BLVD or LLVD contactor, if provided), temperature compensation,
etc, as well as advanced features such as a graphical display, configurable
input/output ports, a charge control function, a built-in web server, etc. The
controller automatically sets the operational parameters of the rectifiers in the
system as these are inserted (plugged-in). Should the controller fail or be
removed from the system, the rectifiers' float voltage then reverts to the
factory set default value of –52.1 V.

Equipment applications

2.2.1.

Lorain CIP Power Systems

The AP6C55CA/CB Lorain CIP power systems are designed to supply a
filtered and regulated –48 V dc source to any imbedded telecommunication
equipment requiring up to 90 A of load capacity. Such equipment may
include indoor or outdoor wireless radio base stations or access concentrators
in cabinets, CEV's, huts, walk-ins, etc, as well as on customer premises.
In many applications, a consistent single point ground topology should be
maintained for all associated equipment. The Lorain CIP power system
complies with the requirements for single point grounding.
2.2.2.

Lorain CIP Access Power Systems

The AP5C55BF power shelf and the AP5C55EA/EB power shelves are
designed specifically to be used together with the AP6C57EA/EB Ring &
Distribution Module to supply a filtered and regulated –48 V dc source and a
continuous 20 Hz ringing supply source to imbedded subscriber loop carrier
telecommunication systems (such as SLC-96 or Series-5).
However, the AP6C57EA/EB Ring & Distribution Module can be used as a
stand-alone unit for applications as required by the end user. You may refer to
the installation manual IM6C57E and user manual UM6C57E that refers to
the Ring & Distribution Module for details.
