Overview, continued
System
Components
The power system accepts alternating current from the commercial
utility or a standby ac power source and rectifies it to produce dc power
for the using equipment. The system’s control and alarm functions
interact with the rectifiers and the office. In addition, the system
provides overcurrent protection and charge, discharge, and distribution
facilities. Battery reserve automatically provides a source of dc power if
the commercial or standby ac fails. Battery reserve can be engineered to
supply dc power for a specific period of time. In normal practice, battery
capacity is sized to provide 3 to 8 hours of reserve time.
AC Input connects the commercial and/or standby ac power sources to
the rectifiers within the system and provides overcurrent protection. In
some applications the ac service is wired directly to the rectifiers and
overcurrent protection is provided at the service panel.
Rectifiers convert an ac source voltage into the dc voltage level required
to charge and float the batteries and to power the using equipment.
Controller provides the local and remote control, monitoring, and
diagnostic functions required to administer the power system.
Batteries provide energy storage for an uninterrupted power feed to the
using equipment during loss of ac input or rectifier failure.
DC Distribution Panel provides overcurrent protection, connection
points for the using equipment, and bus bars used to interconnect the
rectifiers, batteries, and dc distribution.
Battery Connection Panel provides connection points for the battery
strings through battery disconnect fuses or contactors and current
monitoring shunts.

Architecture
ConfigurationsThe GPS 4812/24 is available in two configurations:
•The half height cabinet, shown in Figures 1-1 and 2-2, mounts on
top of a battery stand and can provide up to 800 amperes of dc
power.
•The full height (7-foot) cabinet, shown in Figures 1-2 and 2-3, can
provide up to 1,600 amperes of dc power.
Each cabinet contains ac distribution, dc distribution panels, a battery
connection panel, rectifiers, termination points for load circuits, and a
system controller.
IllustrationsFigure 2-4 shows how supplemental full-height cabinets may be added
to grow the system to 7,040 amperes. The rectifier output buses are
interconnected to permit the cabinet to share current and ensure
common voltage references for all system rectifiers.
Figures 2-5 and 2-6 show open-door views of the half height and full
height cabinets.

4Rectifiers
596 Series A and D
OverviewThe 596 Series A rectifier (55A) and 596D rectifier (110A) operate from
single-phase ac service with a phase-to-phase voltage within the range
of 176-264Vac.
The rectifiers are shipped separately from the cabinets for quick and
straightforward installation into rectifier shelves at the site.
Interconnections to ac input, dc output, and control signals occur
automatically during insertion. The rectifier is keyed to prevent
installation of the wrong rectifier. No settings or adjustments to
potentiometers are necessary. The installer must set the rectifier’s ID
using the ON/STBY switch to allow the controller to learn the rectifier’s
physical location.
The 596A and D rectifiers are UL Recognized for both the U. S. and
Canada, comply with UL1950 (Information Technology Equipment),
and meet EN60950 requirements.
Front Panel Display
Power Switch This three-position switch has two active states:
•It controls the on/standby state of the rectifier.
•It is used to set the rectifier ID.

5AC Input Panels
Overview
AC ServiceThe ac input panel provides the facility to terminate 3-phase ac service
to the GPS 4812/24 system or to distribute individual 1-phase ac
supplies to each of the system rectifier positions. Depending upon the
option ordered, the panel will connect 3-wire (three phases), 4-wire
(three phases + neutral), or individual 2-wire (single phase, either 2 hot
leads or 1 hot lead and neutral) input ac service.
Some systems provide circuit breakers to protect the conductors
providing ac service to the individual rectifiers. Other systems contain a
terminal strip and the conductors are protected by circuit breakers
located in the building’s ac service panel.
Note: All wire sizes were based on the US National Electric Code.
IllustrationsCircuit breaker panels are shown in Figures 5-1, and Figure 5-2 shows
FunctionBatteries are connected to the GPS 4812/24 cabinets on battery
connection panels located in the cabinet directly below or behind the ac
input panel. All panels include the battery shunts and an alarm card that
communicates with the controller to provide battery current and status
information. As options, the panels may include fuses or low voltage
battery disconnect/reconnect (LVBD/R) contactors. When equipped
with contactors, a contactor control card provides local/manual control
of the contactors.
Note: If no battery panel is needed (for full height supplemental cabinets
only), H569-436 G33F is selected as a placeholder in the order.
IllustrationsThe battery connection panels are shown in Figures 6-1 through 6-10.
Note: Battery connection panels are blue; dc distribution panels are
white.
FunctionA variety of dc distribution panels is available for the GPS 4812/24
system, including DIN standard fuse holders and circuit breakers and
U. S. standard fuse holders and circuit breakers. All panels are equipped
with an alarm card. When a fuse operates or a circuit breaker trips, a red
LED on the alarm card lights, the cabinet alarm lights, and the alarm is
transmitted to the controller. Most panels are also available with
contactors to provide low voltage load disconnect.

AC Surge Protection: It is important that ac surges reaching rectifiers do not exceed the capacity of the
rectifier internal surge protection. Protection must be provided external to the GPS system, if necessary, to
limit surge energy reaching the rectifiers. Site surge protection must be coordinated with rectifier internal
surge protection and must clamp at a lower voltage than the rectifier internal protection. The internal
protection voltage and current characteristics of the rectifiers are as follows:

11Maintenance and Replacement
Requirements
SystemWith the exception of the batteries, periodic maintenance specific to the
power system is not required. The ac service for the building must be
maintained with ANSI specified limits. The temperature and humidity
within the power room must be maintained within the limits specified in
Section 10 of this product manual.
Refer to Table 11-A for system replacement parts.
BatteriesThe batteries must be maintained as directed by the battery
manufacturer’s requirements.
RectifiersWith the exception of a fan failure, rectifiers are repaired by
replacement. Refer to “Installing or Replacing a Rectifier” in this
section.

Requirements, continued
Rectifier Fan
Assembly
The expected life of the rectifier fans at 25°C (77°F) is approximately
eight years. The fans in the rectifiers may be replaced in the field.
Two approaches can be taken to fan maintenance.
•The first approach is to replace the fan on a routine basis every
seven to eight years; this ensures that the fan does not fail in the
field under normal operating conditions. This approach is
appropriate when there are no remote alarm facilities at the site.
•The second approach, assuming one has remote alarm capability, is
to wait until the fan fails. The rectifier will safely shut down and
issue both a fail alarm and a thermal alarm. The fan can then be
replaced. Since it is likely that all the rectifiers in that installation
are of roughly the same age, all rectifier fans at that site should be
replaced at that time.
The approach used depends on the location and manning of the site as
well as the monitoring of alarms used at the site. Refer to “Replacing a
Rectifier Fan Assembly” in this section.

12Troubleshooting Preparations
Preliminary
IntroductionThis section provides information needed in preparation for locating and
interpreting visual indicators to help identify problems.
When replacing a part does not correct the problem or visual indicators
do not identify a defective part, notify Lineage Power Technical
Support.
SafetyReview all safety instructions and warnings in the Safety section of the
GPS Installation Guide before troubleshooting the GPS 4812/24.
Warnings
•Hazardous ac and dc voltages and/or energy are present. Caution
should be exercised. Tools must be insulated to help prevent
accidental contact with live surfaces.
•Coordinate all troubleshooting activities with other personnel
that may be working on the system.
Too lsThe following tools are necessary in order to troubleshoot the GPS
4812/24:
•3/16-inch (5mm) Allen-head wrench
•Insulated hand tools
•Calibrated digital voltmeter (DVM)
(0.05% accuracy on dc scale)
PurposeThe troubleshooting procedure described below is used when a trouble
condition has been identified and a technician has been dispatched to the
system location as a first and fundamental step in diagnosing and
correcting the problem.
For all trouble conditions, proceed as follows:
Cabinet Alarm1. Locate the system Galaxy controller. The controller is typically
located in the cabinet identified as BAY ONE. Because a trouble
condition exists, the red alarm on the top of the cabinet will be
illuminated. See Figure 12-1.
System Status2. Determine the system status. For most problems, one or more alarm
and status LEDs will be illuminated. Depending on the controller
type, the following will be displayed:
–system voltage (all)
–system current (Millennium)
–system mode (Millennium)
–system number of alarm/warnings (Millennium)
If the screen is blank, but alarm and status LEDs are illuminated,
call technical support.
If the entire panel is blank, check the controller fuse (F3 basic
power for the Millennium; F2 on the BLJ board for the Vector).
See Figures 12-3 and 12-5. Verify that the controller is getting
power. If not, replace fuse. If the display is still blank, call
technical support.
Alarms Menu3. To view the Alarms Menu:
•Millennium controller:
If the default screen appears normal, press the MENU button.
The main menu appears with “Alarms” blinking. Press ENTER
to obtain the Alarms menu. Additional data appears that will
help to identify the problem.
•Vector controller:
Press the View Active Alarms button and use the displayed
message code to help identify the problem.
