2 Introduction
2.1. General Information
DC Power Plants from APC have unique features that make them easy to install, maintain, and
upgrade. The rectifier units are modular and truly “hot-pluggable” into the shelf assembly
without any separate ac wiring. The Magnum VS 50 has 1 shelf, holding up to five rectifiers for
a rated current of 50 A. The Magnum VS 100 has 2 shelves, holding up to ten rectifiers for a
rated current of 100 A. All system settings are made from a standard PC using a serial cable or
a 10/100 Base T connection. The controller provides monitoring and control functions for each
component of the system and stores alarm listings for system diagnosis and maintenance. For
ease of operation, a display with LCD readout and 5-button keypad can be inserted in rectifier
slot 5
Figure 2.1-1 Magnum VS 50 –48 Vdc Power Plant
The APC Magnum VS is a modular stand-alone -48 Vdc power plant. It is configurable in such
a manner that it will support most typical applications within the specified current ranges (10-100
A) without special application engineering or assistance. DC output distribution is included for
circuit breakers or GMT style fuses or in the 100-A versions, a combination of both. Available
circuit breakers are 30 A or 60 A. GMT fuses can be 1/4 to15 A. A low voltage disconnect
(LVD) is provided to disconnect the battery after deep discharge. A 50-ampere power system is
shown in Figure 2.1-1. A block diagram of a typical 100-ampere power system with fuses and
breakers is shown in Figure 2.2-1.

3 Installation
3.1. Unpacking Equipment
Remove equipment from packing material and inspect for shipping damage or missing items. It
is important to report damage or material shortages to the shipping carrier while a
representative is on site.
If concealed damage or material shortages are found at a later time, contact the shipper to
make arrangements for inspection and claim filing. Refer to Section 10 in the event it is
necessary to return equipment to APC.
CAUTION: Appropriate lifting techniques and safety equipment should be
used to remove equipment from packing.
PLEASE RECYCLE: The shipping materials can be recycled. Please save
them for later use or dispose accordingly.
3.2. Mechanical Installation
Room / Location
NOTE: The APC dc power plant is to be installed in a room, vault, or similar enclosure that is
accessible only to qualified persons in accordance with the regulatory authority having
jurisdiction.
Prior to installation, drawings, floor loading requirements, external alarm points, ac service
entrance, and grounding schemes should all be checked and confirmed. If batteries are to be
mounted in a room separate from the power plant, careful attention should be paid to battery
cable voltage drop effects. Environmental operating temperatures and ventilation/cooling
considerations should also be noted, not just for the power system but also for all other
equipment that may reside in the power room area.
Mounting
The Magnum VS provides brackets to mount on a standard EIA 19 or 23-inch rack. Install the
power system using hardware designed for the rack. To install a Magnum VS 50 on a 23-inch
rack use bracket kit number 0M-2829. To install a Magnum VS 100 on a 23-inch rack use
bracket kit number 0M-2830.
Magnum VS –48 Vdc User’s Manual Page 4
Ventilation
The rectifier modules for this system have fans that provide front-to-rear airflow for internal
cooling. The power system housing should be mounted such that there is free airflow to the
front and back of the unit. [Refer to Section 9.5 for environmental characteristics.] Free airflow
should be ensured so that the power system can provide full power without de-rating.
3.3. AC Power Connections
WARNING: Ensure that all of the external dc and ac circuit breakers are in the
OFF position prior to connecting service to the power plant. Confirm that all
voltages have been removed including any battery sources before proceeding.
AC Connections
The dc power system requires the supply of 85 – 264 Vac, 47 – 63 Hz single phase power. One
alternating current (ac) input on the power system backplane supplies power to the first rectifier
in each shelf. Two inputs supply power to the second and third pair of rectifiers and the fourth
and fifth pair in each shelf. This scheme allows a variety of wiring options. Provided the input
wiring is not overloaded, one, two or all three inputs on each shelf can be jumpered together.
The ambient temperature and number of wires in a conduit must be considered in accordance
with NEC and local requirements. The power system typically ships with the jumpers shown in
the backplane layout of the Magnum VS 50 shown in Figure 3.3-1. The Magnum VS 100
contains two identical backplanes. The input terminals are defined in Figure 3.3-3. If one ac
input cable is used it is typically connected to TRM10, 7 and 4.

Battery Temperature Probe Installation
The temperature probe is used to monitor the battery string temperature. To get the most
representative temperature measurement, the probe should be placed in contact with a battery
cell that is centrally located. The probe should be placed directly in contact with the cell (not the
frame surrounding the cell). Generally, the cell cover can be used; be careful not to allow the
probe body to touch the terminals. Plug the connector end of the temperature probe into J410
of the backplane card. Route the cable as required positioning the probe on the selected
battery cell. Remove the adhesive protection strip from the probe body and press the adhesive
side of the probe on the battery cell cover. Refer to Figure 3.4-3 for details.

3.5. Counter Electro-Motive Force (CEMF) Cell Connections
WARNING: Hazardous energy levels are present on the CEMF connection
area of the plant. Accidental shorting of conductors can cause arcing and
In some applications, a CEMF cell is used to lower the dc voltage delivered to the loads. The
CEMF cell is mounted externally to the Magnum VS. The CEMF connections are located at the
rear of the unit as shown in Figure 3.5-1. Two bus-plates, installed at the factory, bypass the
CEMF connection. If a CEMF cell will be used, remove the bus plate connecting the two CEMF
connection points and install two connection buses before installing the CEMF. The CEMF
connection buses each provide a pair of #10-32 studs on 5/8” centers for connecting two-hole

Cable Size Considerations
The dc load cable(s) should be sized to limit the voltage drop from the dc power plant to the
loads per system design requirements. The cable(s) must also carry the full load current during
battery operation. During battery operation the voltage will be lower and for constant power
loads, the current will typically be higher. If assistance is required to determine the necessary
cables for the application, contact your sales representative or APC.
Circuit Breaker Protected Load Connections (30 or 60 A)
The circuit breaker lug landing connection provides a pair of #10-32 studs on 5/8” centers for
mounting two-hole lugs. A ring size of 6 mm may also be used. A right angle bus bar with two

Front Panel DB9 Connection
The front panel DB-9 connector is used to hook up a standard RS-232 cable (such as APC part
number 0129-XX. A 0129-6 is included with this manual. ). This will allow local access through
a Terminal Emulation program such as HyperTerminal™ or Procomm.™
RJ45 Ethernet Connector
The management card has an RJ-45 connector to support a TCP/IP protocol over a 10/100
BaseT Ethernet Local Area Network (LAN).
Major, Minor and Relay 1 Output Connections
There are three output relays available that provide outputs via Form “C” contacts. The output
relays are named Minor, Major and Out Relay 1. Various system alarm conditions can be
assigned to any of these three output relays. Most alarm conditions are shipped programmed to
Minor or Major Relay. Wago connectors are located on the backplane card mounted in the left
rear of the unit. Refer to the board layout in Figure 3.9-1 for Output Relay connections. The
Wago connectors accept wires 26 AWG to 20 AWG (0.129mm2 to 0.518 mm2). To connect the
relay output, remove ¼ in (6mm) of insulation from the end of the wire. Push down the white tab
on the Wago connector, insert the stripped wire and release the tab to make the connection.
The relay contacts should only be used to switch resistive loads of 0.5 A or less at 60 V or less.
Magnum VS –48 Vdc User’s Manual Page 12
Figure 3.9-3 shows the alarm output connection designations. Whenever possible use the
common and normally closed contacts. If the alarm wiring gets pulled loose, or the controller is
removed, you will get an alarm. The Major relay is energized (C-NO contacts closed) during
normal (non-alarm) operating conditions; the other relays energize when an alarm condition
occurs. If your Major relay wiring uses the C-NO contacts, then a major relay output will be
seen whenever the controller is removed from the shelf.

Magnum VS –48 Vdc User’s Manual Page 19
5 Technical Description
The Power System is designed to supply safe –54 Vdc primary power through the use of up to
10 rectifier modules. The controller will monitor all functions and provides battery management
including controlled battery recharge with temperature compensation and low voltage
disconnect. Integrated dc output distribution supports loads ranging from ¼ A all the way to 60
A. The controller can monitor up to 4 discrete external events with voltage free (“dry contact”)
user inputs.
5.1. Rectifier Management
AC Input Power
The basic component of the power system is the rectifier module, which rectifies utility ac into
nominal 48 Vdc. Each rectifier module requires 85 – 264 Vac, 47 – 63 Hz single phase power.
Available cord sets include a variety of blade and twist lock plugs. Dedicated wiring inside
conduit can also be used.
DC Output Power
The dc outputs of all the rectifiers in the system are connected to a common bus that is rated to
carry the current of the entire system. The rectifier modules will equally share the entire load,
independent of the controller. The rectifiers will continue to provide dc power (-54.5Vdc) if the
controller is removed or fails.
Rectifier alarms reporting
The rectifier has numerous sensors inside the unit that monitor fan fail, high temperature,
high/low voltage, etc. These rectifier sensors trigger outputs that are monitored by the
controller. In addition rectifier current is measured inside each rectifier. The controller can
trigger output relays in the event of a rectifier alarm. Refer to Section 5.5 for controller functions.
5.2. System Management
System Voltage Monitor and Control
The controller monitors and adjusts the system voltage. It uses a voltage trim input to the
rectifier to precisely control the dc output voltage. In the event of controller removal or failure,
individual rectifiers will default to the analog voltage level (-54.5 Vdc) preset at the factory.
System high and low voltage alarms are reported by the controller.
Magnum VS –48 Vdc User’s Manual Page 20
System Current Monitor
The controller monitors individual rectifier currents and displays total system current as a sum of
rectifier currents. Load current can be found by adding battery current to system current.
Battery Current is positive when the battery is discharging.
Sys Current + Batt current = Load Current
For example, if the battery is charging the Batt Current reading could be (–) 10 A, Sys Current
reading could be 50 A. Load Current would be:
Sys Current + Batt current = Load Current
50 A + (-) 10 A = 40 A.
If the battery is discharging the Batt Current reading could be 10 A, Sys Current reading could
be 30 A. Load current would be:
Sys Current + Batt current = Load Current
30 A + 10 A = 40 A.
System Status and Alarm Reporting
The controller will monitor system, temperature. The controller reports system high and low
temperature alarms.
5.3. Load Management
Circuit Breakers
Distribution is included for up to 2 circuit breakers or eight GMT fuses per 50-A shelf. The circuit
breakers can be 2 X 30 A or 1 X 60 A in each shelf. The GMT fuses are 8 X ¼ to 15 A in each
shelf. When a circuit breaker trips, a normally open switch closes and the controller reports a
CB alarm. Alarms are reported only when a breaker is tripped. When a breaker is turned off, no
alarm is generated. Circuit Breaker Alm 1 or 2 are reported when a circuit breaker in the top
shelf trips. Circuit Breaker Alm 3 or 4 are reported when a circuit breaker in the bottom shelf
trips. Because of this, if a Magnum VS 100 has GMT fuses in the top shelf and 2 circuit
breakers in the bottom shelf, the circuit breakers will be labeled CB1 & CB2 on the front panel,
but Circuit Breaker Alarm 3 & 4 will be reported. If a Magnum VS 100 has GMT fuses in the top
shelf and 1 circuit breaker in the bottom shelf, the circuit breaker will be labeled CB1 on the front
panel, Circuit Breaker Alarm 3 will be reported. If a Magnum VS 100 has 1 circuit breaker in the
top shelf and 1 circuit breaker in the bottom shelf, the circuit breakers in the bottom shelf will be
labeled CB2 on the front panel, but Circuit Breaker Alarm 3 will be reported. To disconnect a
load attached to a circuit breaker, move the lever down to the “OFF” position.
Magnum VS –48 Vdc User’s Manual Page 21
GMT Fuses
When a GMT fuse trips, a fuse element burns out allowing the indicator to connect dc power to
the alarm contact. This turns on the fuse alarm LED on the fuse panel indicating the affected
group and the controller reports a fuse alarm. Each controller fuse alarm combines alarms from
4 individual fuses:
Fuse F1 to F4 : Fuse Alarm 1. Fuse F5 to F8 : Fuse Alarm 2.
Fuse F9 to F12 : Fuse Alarm 3. Fuse F13 to F16 : Fuse Alarm 4.
To disconnect a load attached to a GMT fuse pull the fuse straight out of the fuse holder base.
5.4. Battery Management
Battery Charging
Battery charging is integrated into the dc power system to support the primary function of
providing power to the load. Accurate measurement of battery parameters such as voltage,
current and temperature are used to maintain and protect the batteries attached to the power
plant.
Charging the battery at the correct rate reduces battery heating, increases the charge returned
to the battery and prevents excess hydrogen generation or, in the case of Valve Regulated Lead
Acid (VRLA) batteries, possible thermal runaway. The Magnum VS operates as a current
limited constant voltage battery charger. The current limit value is set by the controller’s Battery
Maximum Recharge Current parameter and is normally based on the size of the battery plant in
ampere-hours.
Consult the battery manufacturer for the recommended maximum charging current. This is
frequently expressed as a percentage of the battery's 20-hour ampere-hour capacity rating,
commonly abbreviated as "C". For example, the maximum recharge current in amperes may be
expressed as 0.2C, 20% C or C/5, all of which are equivalent. If the battery used has a capacity
of 120 Ah, then the 0.2 C max current is 24 amperes. Manufacturers typically specify max
recharge current between 0.1C to 0.3C (C/10 to C/3). Avoid high recharge rates that may induce
elevated battery temperatures that can lead to thermal runaway. A 0.1C max recharge current
is generally a conservative value that will result in a 90-95% recharge in 12-15 hours, depending
on the initial depth of discharge. In this case charging current will begin to taper (reduce) from
the current limited value after 3.5 - 7 hours.
Typically four 12-volt batteries are connected in series to form a battery string. The ampere-hour
rating for one 12-volt battery will equal the Ah rating of the string. For multiple parallel strings,
add the Ah rating of each string together to get the total Ah rating.
Magnum VS –48 Vdc User’s Manual Page 22
Battery Equalization
Battery equalization equalizes the specific gravity of the electrolyte in the cells of a battery. It is
accomplished by applying a controlled overcharge to the battery. Equalization may be
appropriate (1) after a battery has been in float charge for extended periods time, (2) after a
battery has been significantly discharged, or (3) at the time of initial battery installation. There
are three methods by which the Magnum VS controller may initiate equalization: manual,
periodic and automatic. Manual Equalization is a one time equalization initiated by the user.
Periodic Equalization occurs after a set number of days. Automatic Equalization occurs after a
set time period of ac power failure or a set percentage of battery ampere-hour discharge. The
factory default for all equalization methods is OFF. Refer to the Equalization setup parameters
in the table of Section 6.4. The maximum equalization voltage is limited to the system maximum
voltage adjustment of -56.5 Vdc.
Presently, the equalization function is only accessible through the controller display keypad. A
future upgrade to the network management card is planned that will allow equalization to be
accessible remotely.
Battery Protection
An external disconnect should be mounted at the battery string to protect the system from the
high energy stored in the battery if a short occurs. The battery LVD will not be energized until a
battery string is installed with the proper polarity and the battery disconnect switch is turned on.
The battery connections are to be used for the battery only. Do not attach loads to the battery
connections or erroneous battery current will be reported. The controller reports Battery high
and low voltage alarms and LVD alarms.
Battery Temperature Monitoring
Battery temperature is monitored using a probe attached to the battery casing. The controller
reports Battery high and low temperature alarms.
Battery Temperature Compensation
The Battery Float Voltage is set to the value recommended by the battery manufacturer in order
to maintain correct battery charge at 25ºC. As temperature rises, electrochemical activity in a
battery increases. Similarly, as temperature falls, electrochemical activity in a battery
decreases. As temperature rises, charging voltage should be reduced to prevent overcharge
and possible thermal runaway. As battery temperature falls, voltage is increased to prevent
undercharge. The dc power system uses Battery Temperature compensation to change output
voltage to compensate for temperature changes monitored at the battery temperature probe.
This temperature compensation function is programmed into the controller using the
compensation parameters settings. Default settings can be changed to values recommended
by the particular battery manufacturer. The controller will not allow the system voltage to be
adjusted beyond the range of –47 Vdc to –56.5 Vdc.
Magnum VS –48 Vdc User’s Manual Page 23
Battery Low Voltage Disconnect
In order to prevent damage to the battery due to deep discharge, the dc power system has
hardware and software support for a battery Low Voltage Disconnect (LVD). When the battery
voltage reaches the threshold set by the LVD 1 Trip Voltage setting during discharge, the dc
power system will activate the LVD contactor to disconnect the battery from the system. The
LVD will remain open until ac power is restored to the system and the bus voltage reaches the
level defined by the LVD 1 Reset Voltage variable. The LVD control can be disabled on the
LVD parameters screen in the controller.
NOTE: The LVD is normally energized and must be commanded to open. This assures that
the LVD will remain closed even if the controller fails or is removed.
The LVD will not be energized until a battery string is installed with the correct polarity and the
battery disconnect switch is turned on. This will prevent the battery from being hooked up
backwards and damaging the rectifiers and/or the loads. Once the battery is connected
correctly and the LVD is closed, the LVD will open only in low voltage situations. The battery
connections are to be used for the battery only.
Battery Functional Test
The controller is able to functionally test the battery. This is a short duration test intended to
confirm that the battery can deliver current to the load without an unusual drop in system
voltage. Excessive voltage drop may be an indication of high resistance electrical connections,
high battery internal impedance or impending battery failure. For the test the controller lowers
the system voltage sufficiently that the batteries will deliver the current required by the load
equipment and thereby start to discharge. The controller monitors the voltage drop to determine
if the battery is good or bad. A collapse of voltage will not cause an interruption in power to the
load, as the rectifiers remain operational and will continue to support the load if this occurs.
Functional test defaults are a 10 second duration and -48 V pass/fail voltage threshold. Very
high or low equipment loads relative to the size of the battery may invalidate the results of this
test. Presently this test may only be initiated manually via the controller with display keypad. A
future upgrade will add this capability to the network management card for remote access.
Counter Electro-Motive Force Module Connections
A connection is provided to connect a Counter Electro-Motive Force (CEMF) Module. A CEMF
is a semiconductor device connected in series with a battery and used to reduce the voltage to
loads that cannot tolerate the “normal” main cell voltage. The CEMF cells are automatically
switched out of the circuit when the discharge voltage drops to a predetermined level and are
automatically switched back into the circuit when the battery approaches its normal float value.
Magnum VS –48 Vdc User’s Manual Page 24
5.5. Controls and Indicators
Controller with Display
The Magnum VS may be equipped with an optional advanced controller. This controller has an
LCD display and a 5-button keypad. This controller uses the normal control card slot as well as
the adjacent slot for rectifier 5. Most common parameter monitoring and programming can be
made right at the power system using this interface. Any other changes must be made either
locally using a PC or remotely by interface to the network management card. Refer to Section 6
for further information. There are five LEDs visible on the control card. The Major LED (Red) is
on when the Major Relay is de-energized. The Major Relay is energized when there is no
alarm. This will produce a major relay output even when all power is lost. The Minor LED
(Yellow) is on when the Minor Relay is energized. The Out Relay LED (Yellow) is on when the
Out Relay is energized. The DC OK LED (Green) is on when the voltage is between 50 and 57
Vdc. The green LED behind the front panel is slowly flashing when the controller is processing
data.
Controller without Display
There are no switches or controls of any kind on this controller. All parameter changes or
viewing of status is made either locally using a PC or remotely by interface to the network
management card. Refer to Section 6 for further information. LED indicators and relay
operation is identical to that found on the controller with display.
5.6. Alarm Outputs (Output Relays)
There are three alarm output relays designated Out Relay 1, Minor, and Major. Various system
parameters may be programmed to activate any of these output relays when set thresholds are
exceeded or specific conditions occur. Out Relay 1 can also be routed or “mapped” to “Out
Relay 1-6,” “Minor Relay,” “Major Relay” or “Ignore.” This feature makes it possible for a single
alarm condition to activate multiple alarm output relays including the Minor or Major alarm relay.
For information on making wiring connections to the alarm output relays refer to Section 3.9
In addition to the output relays described above there are 5 outputs that do not support actual
hardware. These are called Output Relay 2 through 6. While the relay hardware is not
available, the programming can still be used to provide more detailed information through the
network management card. Using the actual relay 1 and the 5 virtual relays 2-6, six different
parameters can be alarmed with unique messages through the network management card.
Various system parameters may be programmed to activate any of these output relays when set
thresholds are exceeded or specific conditions occur. Relay 2-6 can also be routed or “mapped”
to “Out Relay 1-6,” “Minor Relay,” “Major Relay” or “Ignore.”
Out Relay 1-6 can be renamed using the Relay Alias setup screen. Each relay name can be up
to sixteen characters in length. This name will appear in the messages generated by the
Magnum VS –48 Vdc User’s Manual Page 25
network management card. This can be used to give specific information on the exact nature of
the active alarm.
5.7. External Alarm Inputs (User Input)
The controller can monitor any external device that uses a voltage free (“dry contact”) switch or
relay to output status information. The four external user inputs can be routed or “mapped” to
alarm output relays. Available assignments are “Ignore”, “Major”, “Minor”, and “Out Relay 1.”
For information on wiring connections to these inputs refer to Section 3.9
5.8. Network Management Card - Local & Remote Monitoring
The Magnum VS controller includes an APC AP9617 Network Management Card which allows
both local and remote access to the power system. The AP9617 is a web-based management
product that uses multiple, open standards such as Telnet, HTTP, and SNMP to provide full
management of supported devices. The following is a list of some of this Management Card’s
features:
- Provides a Data Log accessible by FTP or a Web browser.
- Provides an Event Log accessible by Telnet, FTP, or a Web browser
- Detects connection speed of 10/100 MB per second.
- Generates Email notifications for DC Power Plant events and system events.
-Limits SNMP traps and Email notifications based on the severity level of the DC Power Plant or
system events
The Management Card has two internal interfaces (control console and Web interface) which
provide menus with options that allow you to manage the DC Power Plant and the Management
Card. The Management Card’s SNMP interface also allows you to use an SNMP browser with
the PowerNet® Management Information Base (MIB) to manage the DC Power Plant.

6 Operation
6.1. Description
The Magnum VS is designed for years of operation with no user input. The power system is
pre-programmed at the factory with all parameters needed for normal operation. The front panel
LEDs and the alarm output relays, indicate the general health of the unit. There are 2
controllers available for this power system. A LCD display with keypad (0M-2997) will access
most operator functions from the front of the unit. This controller is described in more detail in
Section 6.3. A controller without display (0M-1650) is described in more detail in Section 6.5.
This controller requires local parameter changes to be made using a PC.
6.2. Controller Card Jumpers
System voltage J5
The positioning of jumpers on header J5 will determine the operating voltage of the controller
card operates. Options include –48 V, +24 V, +48 V, or –24 V systems. The Magnum VS is
only a –48 V system. The only setting allowed is the –48 V setting, which is J5-1 jumpered to
J5-6 and J5-2 jumpered to J5-7.
Remote Lockout J8
It is possible to make parameter changes to the controller card through the RS232 port or
through the 10/100 Base T port of the network management card. The controller card is
shipped with a jumper between pins J8-2 and J8-3, allowing such parameter changes. If the
user wishes to disable the remote configuration feature, then the jumper is moved to pins J8-1
and J8-2.
Firmware Programming Enable J9
When the operating system is initially installed at the factory, J9-1 is jumpered to J9-2. This
setting interferes with normal operation. To ensure normal operation, the controller card is
shipped without this jumper. During normal operation, the only setting allowed is no jumper

6.5. Controller without Display
This controller does not have a built in display and keypad. It does not use the fifth rectifier slot.
All parameter changes or viewing of status is made either locally using a PC or remotely by
interface to the network management card. Refer to Figure 6.5-1 for the front panel layout.
Figure 6.5-1 Magnum VS Controller without Display
6.6. Operation Using the RS-232 Comm Port
The front panel DB-9 connector provides a means to connect a PC to the controller locally to set
controller parameters and to view status. To connect to this port use a straight through cable
such as APC part number 0129-XX. A 0129-6 is included with this manual. . Refer to the
Network Management Card Quick Start Manual or the User's Guide supplied on the CD shipped
with the system for details on how to communicate to the controller using a terminal emulation
program like HyperTerminal
NOTE: The smart-signaling cable (940-0024 or 940-1524) referenced in the Quick Start Manual
and User's Guide does not apply to the Magnum VS. Use a straight through cable such as APC
part number 0129-XX. A 0129-6 is included with this manual.
Communication to the controller through the local serial port is accomplished via the network
management card's Control Console interface. This is a simple text based menu interface.

or Procomm
(TM
Magnum VS –48 Vdc User’s Manual Page 36
6.7. Operation Using the 10/100 BaseT Ethernet Port
The RJ-45 10/100 Base-T port is primarily intended for connection to an intranet for remote
access to the DC power system. However with the use of a crossover cable or a hub, a direct
PC to 10/100 Base-T local connection may also be made.
After the Management Card is configured and running on your network, you can use several
different interfaces to access the Management Card: Web, Telnet, SNMP and FTP.
-The Web interface uses a web browser such as Microsoft ® Internet Explorer 5.0 (and higher)
or Netscape ® 4.0.8 (and higher) to configure Management Card options and to view DC power
system status, alarms and events.
-Telnet is used to access a Management Card’s Control Console and is the same user interface
available via the local RS-232 serial port.
-SNMP access is available after you add the PowerNet MIB to a standard SNMP MIB browser.
-FTP access is used to download new firmware to a Management Card, or to access a copy of a
Management Card’s event or data logs.
Complete documentation for the use of the management card accompanies the DC power
system in the form of a Quick Start Guide and a CD. The CD contains electronic copies of
User’s Manuals along with the necessary software utilities to support the management function.
Some of the functions supported by the network card are not supported by this power system.
6.8. Operation using Network Management Card Web Browser
Interface
The location, description, and factory programmed default value for each of the Magnum VS
system parameters accessible via a Web browser is found in the table below. The table also
shows all of the status and information screens with typical displays. The location of a
parameter screen is shown in brackets, for example: [Power Modules/Rectifiers]. This table is
organized alphabetically by parameter name.

6.9. LVD Operation
In order to prevent damage to the battery due to deep discharge, the dc power system has a
Low Voltage Disconnect (LVD). When the battery voltage reaches the threshold set by the LVD
1 Trip Voltage setting during discharge, the dc power system will activate the LVD contactor to
disconnect the battery from the system. The LVD will remain open until ac power is restored to
Magnum VS –48 Vdc User’s Manual Page 44
the system and the bus voltage reaches the level defined by the LVD 1 Reset Voltage variable.
The LVD control can be disabled on the LVD parameters screen in the controller.
The LVD will not be energized until a battery string is installed with the correct polarity and the
battery disconnect switch is turned on. This will prevent the battery from being hooked up
backwards and damaging the rectifiers and/or the loads. Once the battery is connected
correctly and the LVD is closed, the LVD will open only in low voltage situations. The battery
connections are to be used for the battery only.
6.10. Programming Output Relays
Any alarm condition such as System High Voltage Alarm, Battery Discharge Alarm or Rectifier 1
of n Alarm can be programmed to any of the eight output relays. Programming alarms to the
output relays 1-6 will give a much better idea of what the failure is before actually visiting the
site. Using the default programming, over twenty conditions could cause activate a minor relay.
However, if you program Battery Discharge Alarm to Output Relay 1, you will know exactly what
the alarm is just by knowing that output relay 1 is on. The network management card also
displays the output relays individually and can be set up to e-mail these messages.
Output relay mapping options are Ignore, Major, Minor and Output Relay 1-6. To program the
alarm to an output relay find the alarm setup screen for the desired alarm from the table in
Figure 6.8-1. The Ignore setting will not send an alarm to any display or relay. Programming
the alarm to Major, Minor or Output Relay 1 will send the alarm to the relay output connector on
the back of the plant, turn on the appropriate front panel LED, and will send the alarm to the
network management card. Programming the alarm to Output Relay 2-6 will not send the alarm
to the relay output connector on the back of the plant, but will turn on the front panel Out Relay
LED, and will send the alarm to the network management card. For instance, go to the
Batteries / Parameters screen and program Battery Discharge Alarm to Output Relay 1. When
the battery discharge current goes above the default setting of 5 Amps, the alarm will come on,
the Out Relay contact will energize, the front panel Out Relay LED will come on and the network
management card will report Output Relay 1 is on.
Most alarms are originally assigned to a minor or major relay. Usually it is desirable to keep the
minor and major assignments when programming to the output relays. To do this, go to the
output relay-programming screen and map the relay back to the desired minor or major relay.
For instance, go to the I/O / Output screen and program Relay 1 to Minor Relay. When the
battery discharge current goes above the default setting of 5 Amps, the alarm will come on, the
Out Relay contact will energize, the Out Relay LED will come on and the network management
card will report Output Relay 1 is on. In addition, the Minor Relay contact will energize, the front
panel Minor LED will come on and the network management card will report the Minor Relay is
on. With this scheme of programming, you will know that you have a minor alarm and
specifically that the batteries are discharging.
Out Relay 1-6 can be renamed using the Relay Alias setup screen. Each relay name can be up
to sixteen characters in length. This name will not appear in the alarm summary, but will appear
in the messages generated by the network management card. This can be used to give specific
Magnum VS –48 Vdc User’s Manual Page 45
information on the exact nature of the active alarm. Using the example above, if you use the
default programming the message “A minor relay in the power plant has been activated.” Using
the relay mapping and aliasing you could get the additional message “An output relay (1, Batt
Discharge) for the power plant has been activated.

Magnum VS 100
Terms of Warranty:
APC warrants that the Product shall be free from defects in materials and workmanship, for a period of two (2) years from the date of
shipment.
Warranty Procedure
If initial physical inspection results in identification of a material or workmanship flaw(s) that could impair Product performance as defined by
APC’s electrical and physical specification in effect at the time of shipment, and if this flaw(s) is not due to transportation damage or installation
abuse, contact APC or call the 24-hour emergency number, (800) 800 4APC, to request assistance.
You will be provided either a) an RMA number with instructions for return of the equipment or component(s) to the APC factory service center, FOB
destination, freight pre-paid, for examination, or b) for non-returnable systems and equipment, notice to wait until an APC authorized service
representative arrives at the site to inspect the equipment. Repaired or advance replacement modules or circuit components will normally be
available within 24 to 48 hours of receipt of equipment or RMA.
Warranty Obligations - Repair or Replacement
If, during the warranty period, the Product is found to be physically or electrically faulty due to defective materials or workmanship, the defective
Product(s) or component(s) will be repaired or replaced at the sole option of APC. If the procedure outlined above for contacting APC immediately
after identifying a material or workmanship flaw(s) that could impair Product performance has been properly followed, such repair or replacement of
Product(s) or component(s) shall include all charges for replacement materials or repair labor. Costs incurred for replacement installation including,
but not limited to, installation equipment, travel expenses of an APC representative(s), and costs of installation material transportation expenses are
not included as a part of this warranty. Any replacement components or materials furnished under this warranty may be new or factory
remanufactured. THIS WARRANTY DOES NOT COVER CONSUMABLES OR PREVENTATIVE MAINTENANCE ITEMS. REPAIR OR

PERIOD.

bought. This Warranty is not transferable or assignable without the prior written permission of APC.
This limited warranty does not cover damage due to external causes, including accident, abuse, misuse, servicing not authorized by
APC, usage not in accordance with Product instructions, failure to perform preventative maintenance, and problems cause by use of
parts and components not supplied by APC. This limited warranty does not apply to Products from which the serial numbers have been
removed, or to conditions resulting from improper use, accidents, external causes, including installation, relocation of hardware, service
or modifications not performed by APC or its authorized service providers, or operation outside the environmental parameters specified
for the Product. APC does not warrant that the operation of any Product will be uninterrupted or error free. Warranty service may not be
performed if APC or other suppliers reasonably believe conditions at the Buyer's site represent a safety or health risk.
