• Standard selection of insulated hand tools.
• Proper tools for crimping the selected cable lugs.
5.1.2 Recommended Test Equipment
• Digital Multimeter
5.1.3 Equipment Inspection
Remove equipment from packing material and inspect for shipping damage to verify the safety
and operational suitability for the installation site. [Refer to Section 1.3]
5.1.4 Safety Precautions
***** WARNING *****
The MX28B600 DC power plant is supplied from a nominal 220V AC, 60 Hz source. Keep
the AC input enclosure cover in place when the system is operational or energized.
***** WARNING *****
Hazardous energy levels are present on bare conductors in the -48V DC distribution
connection area of the plant. While certain engineering precautions have been designed into
the system, accidental shorting of distribution conductors can cause arcing and high
currents that can cause serious burns or other physical harm.
It is recommended that:
• Any jewelry, rings or watches be removed while working on this equipment.
• Handles of all wrenches, screwdrivers, cutters and pliers be insulated.
• Shafts of screwdrivers must be wrapped in electrical tape or otherwise insulated.
*****WARNING*****
NOTE: OVER TEMPERATURE WILL LEAD TO RECTIFIER SHUTDOWN.
Rectifier fan inlet filters are available for dusty or hostile environments. The filters
require periodic cleaning and/or replacement. Monitor filters to determine a maintenance
cycle for filter cleaning. Rectifiers will signal OVER TEMPERATURE WARNING and
eventually fail if filters are not maintained.
5.1.5 Room/Locations
NOTE: The power plant is designed for installation in a room, vault, or similar enclosure
that is accessible only to qualified persons in accordance with NEC or other
authority having jurisdiction.
12
MX28B600-48V
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 for all other equipment
that may reside in the power room area.
5.1.6 Mounting
Front mounting on standard 23” rails, and/or installation in appropriately vented cabinets is
possible.
5.1.7 Ventilation
The rectifiers have fans that provide front to rear airflow for internal cooling. The MX28B600
housing should be installed and/or mounted such that there is free airflow to the front, top, and
bottom of the unit. [Refer to Section 4.9 for environmental characteristics.]
5.2 AC Service and Ground Connections
***** WARNING *****
Ensure that all of the DC and external 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.
The MX28B600 DC power plant requires the supply of 208/220/240V AC, single-phase, 50/60
Hz power through individual external 20-amp two-pole circuit breakers to the AC input terminal
block connections for each rectifier in the system. (The AC wiring, from the AC input terminal
block connections to the hot-pluggable AC input connector for each rectifier, is factory
installed.)
The AC input enclosure, located at the top left rear of the MX28B600 housing, is provided with
three one-inch conduit entry holes. Inside, 3 terminal strips for AC input power connection and a
separate “Earth Ground” bar for connection of the safety ground wires are provided. The
terminal blocks are labeled as Position 1 through Position 4 for shelves 1, 2, and 3 with each
position having inputs designated “L1” and “L2” for connection of the two AC wires. Positions
1-4 correspond to the respective rectifier shelf positions from left to right.
The suggested wire size is #10 AWG rated at 90°C or higher; however, the ambient temperature
and number of wires in a conduit must also be considered in accordance with NEC
requirements. It is suggested that feeds for four rectifiers (8 wires) and one safety ground wire
be run in a one-inch conduit; however, be sure to follow any local electrical wiring codes.
If the AC input power is provided from a three-phase distribution panel, the circuit breaker
positions should be selected such that the load is balanced as much as possible.
5.3 Battery Connections
An external circuit breaker or fused disconnect (Customer supplied) is recommended in the
negative line (located at the battery end of the related cables) to protect the cables from the
battery to the MX28B600 DC power plant. The power plant can monitor auxiliary contacts
from this breaker.
13
MX28B600-48V
5.3.1 Cable Sizing Considerations
The battery cable(s) should be sized sufficiently large to limit the voltage drop from the
MX28B600 DC power plant to the battery during charging in accordance with system design
requirements. The cable(s) must also carry the full load current during battery operation. If
assistance is required to determine the necessary cables for the application, contact your sales
representative or APC DC Network Solutions Inc.
5.3.2 Connecting the Cables
The battery cable connections are located at the center rear of the unit as shown in Figure 4.6-1.
The battery positive (return bus) and battery negative (-48V bus) buses each provide two sets of
threaded 3/8”-16 holes on one-inch centers for connecting two-hole battery cable lugs. Connect
the battery cables as applicable using 3/8”-16 bolts (not provided) and tighten them with a
torque wrench to 200 in-lbs.
***** CAUTION *****
Make certain that the battery polarity is correct when making connections to the
MX28B600 DC power plant. Incorrect connection could cause severe equipment damage.
5.4 DC SYSTEM GROUNDING
THE POSITIVE BATTERY CONNECTION (RETURN BUS) FOR THE POWER
PLANT MUST BE CONNECTED TO THE MASTER STATION GROUND. THE
RIGHT SIDE SECTION (when viewed from the front of the unit) OF THE RETURN BUS
PROVIDES A PAIR OF THREADED 3/8”-16 HOLES ON 1-INCH CENTERS FOR
CONNECTION OF A TWO-HOLE LUGGED CABLE TO THE MASTER STATION
GROUND. DETAILS FOR THIS CONNECTION SHOULD BE PROVIDED IN THE
SITE ELECTRICAL GROUNDING PLANS.
5.5 Rectifier Installation
The APC DC Network Solutions Inc. Model MRF28H54BV rectifiers are shipped in separate
containers. Follow the procedure below to install a rectifier.
1) Remove the rectifier from its shipping container.
2) Slide the rectifier into the shelf between the guides until it is fully seated.
3) Locate the rectifier retaining screws in the bag the manual came in.
4) Fasten the rectifier in place with the rectifier retaining screw.
Since all adjustments are made from the system control unit, no rectifier adjustments are
necessary.
NOTE: All “FLOAT” – “BOOST/EQUALISE” switches (one is located on the front of
each rectifier in the system) must be set to “FLOAT” to allow the MX28B600 to
control the output voltage properly.
5.6 Alarm Connections
The alarm connections for all rectifiers, breakers, and fuses are factory pre-wired. The
MX28B600 DC power plant, however, permits the user to program the system alarms in various
ways.

The breaker adapter kit includes all necessary mounting hardware.
An optional load shed circuit is available. This option will disconnect any unessential loads
from the rest of the system. Loads hooked up to the lower left tier (CB 26-35) will be
disconnected. This will preserve the battery run time for essential loads. When hooking up the
loads, ensure that they are divided correctly.

5.7.2 Installation of Circuit Breakers and Fuses
5.7.2.1 Plug-in Circuit Breakers
1) Remove the circuit breaker cover panel and the plastic cover(s)/insert(s) from the
desired location(s).
2) Install the circuit breaker(s) by snapping the top terminal onto the upper bus bar and
rotating the unit down until the second terminal snaps onto the breaker termination
post as shown in Figure 5.7-1. The breaker alarm terminals are designed to make
contact with the alarm terminal board as the breaker is snapped into place.
NOTE: Circuit breaker alarm contacts close when the circuit breaker is tripped
but not when it is turned OFF.
***** CAUTION *****
During circuit breaker installation, carefully align the breaker alarm terminals with the
alarm terminal board to avoid breaker terminal damage.
3) Reattach the circuit breaker cover panel.
Figure 5.7-1. Installation of Circuit Breakers
5.7.2.2 Optional GMT Fuses
Fuseholders that accommodate GMT fuses are located on the interface card mounted in the top
left side of the unit. These fuseholders are only connected to -48V DC if the system has been
purchased with the GMT fuse option. This option supplies -48V DC to the fuseholders through
18
MX28B600-48V
a 50 A. circuit breaker located in circuit breaker Position 1. The interface card provides
fuseholders for eight fuses, labeled “F1” through “F8”, which can be used for small -48V DC
loads. The maximum fuse size that should be used is 10A.
5.7.3 Load Connections
5.7.3.1 Circuit Breakers
Connections for -48V DC loads require standard two-hole lugs for #10 screws on 5/8” centers
and are located directly above the corresponding circuit breaker. The load returns connect to the
respective return bus located just above and rearward of the breaker connection points. The
upper tier is seen in
holes on 5/8” centers and four sets of threaded ¼”-20 holes on ¾” centers for connection of twohole lugs on load return wires.
5.7.3.2 Optional GMT Fuses
Connections to the GMT fuses are made at terminal block connectors labeled “F1” through “F8”
that are located on the interface card mounted in the top left side of the unit. Each connector has
two positions, labeled “-48V” and “RTN”, for connection of the -48V DC load and load return
wires.
Figure 4.7-1. The return buses provide a total of 40 sets of threaded #10-32
5.8 Battery Temperature Probe Installation
The optional 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.
1) Plug the connector end of the temperature
probe into J5 the control unit backplane
card.
2) Route the cable as required to position the
probe on the selected battery cell
3) Remove the adhesive protection strip from the probe body and press the
adhesive side of the probe on the battery cell cover.
5.9 Power-Up and Checkout
Before initiating power-up and checkout, ensure that the following conditions exist:
J5
1) Make sure that the external circuit breaker protecting the cables from the battery to
the power plant is turned OFF (the battery cables should be connected to the power
plant, but the battery should not
be connected).
2) Make sure that all load circuit breakers are turned OFF (including the one feeding the
GMT fuses if the unit has the GMT fuse option).
3) Verify that all rectifiers have been installed.

5.9.1 Apply AC Power
Turn on the circuit breakers that supply AC power to the rectifiers in the MX28B600 DC power
plant. The main screen should appear on the control unit display (see Figure 5.9-1). The display
on the control unit is a 2-lines by 16-characters display. The cursor cycles below the characters
of the active selection on the display. Information shown in the second line of Figure 5.9-1 that
extends beyond 16 characters (to the right of the “S” in “ALARMS”) can viewed on the control
unit display by using the scrolling controls (refer to Section 6 for operation of the control unit).
NOTE: When AC power is initially applied, there is a 60-second period during which no alarms
are reported.

5.9.2 System Parameters Verification/Adjustment
The MX28B600 system control unit is delivered with pre-programmed parameter default
settings. A complete listing and description of all system configuration parameters as well as
displayable system status and information is provided in Section 6. Read Section 6 to gain an
understanding of and how to use the operational features provided by the MX28B600 DC power
plant. As a minimum, the following parameters should be verified and adjusted, if required,
before connecting batteries or loads to the power plant:
1) Battery Float Voltage - default = -54.00V DC (Check the manufacturer’s
recommendation for the batteries being used in the system.)
2) Battery Maximum Recharge Rate - default = 50A. (Bellcore specifications
recommend a maximum charging rate of capacity (in Ampere-hours) divided by 20
hours; check the battery manufacturer’s recommendation.)
3) System Voltage - measurement ≅ -54.00V DC (This is a measurement by the system of
the DC output bus voltage.)
4) LVD Option - default = “Enable” (If the MX28B600 does not have an LVD installed,
this should be changed to “Disable”.)
5) Rectifier Information - Check the rectifier information displays to verify that all
rectifiers installed can be viewed on the control unit display and that no rectifier alarms
are active.
Section 6 provides location information for these parameters and how to make changes if
required.
5.9.3 Full System Power Up
To complete a full system power up, perform the following steps
1) Turn OFF all the circuit breakers that supply AC power to the rectifiers in the
MX28B600 DC power plant.
2) Turn on the external circuit breaker from the battery to the power plant.
20
MX28B600-48V
3) Turn on all the circuit breakers that supply AC power to the rectifiers in the MX28B600
DC power plant.
4) Load circuit breakers may now be turned on as required.

MX28B600-48V
6. SETUP, ADJUSTMENTS, AND OPERATION
6.1 User Interface
The MX28B600 control unit provides a user interface designed with a hierarchical menu that
can be viewed on the 32-character display by “navigating” with the “Õ” (left), “Ö” (right), “×”
(up), and “Ø” (down) arrow keys located on the front panel. The selected item on the display is
identified by the cursor cycling beneath its characters.
The “M” (modify) key and the arrow keys are used to set parameters and text to customize the
system operation for a specific application. Items that can be modified have "m+" in the upper
right corner of the display. (If a security level higher than the one presently set is required to
modify the parameter, "s+" is displayed instead of “m+”.) Status, alarms, and information
screens have "+" in the upper right corner of the display (or “#” in the case of rectifier
information screens) and cannot be modified. When AC power is initially applied, there is a 60second period during which no alarms are reported.
Pressing the "M" key on the front panel will change the "m+" to "M+", indicating that the
parameter can now be changed using the arrow keys. Some parameters can be changed to other
predefined selections by pressing the up or down arrow keys to display an alternative selection.
These parameters can be recognized after the “M” key is pressed by the cursor cycling beneath
the characters of the selection. For other parameters, such as text and most numeric values, after
the “M” key is pressed the cursor will be displayed under an individual character. The right or
left arrow key is used to position the cursor below the character to be changed and the up or
down arrow key is used to "spin" the digit or letter to the desired value. When the desired
changes have been made to an individual parameter screen, the “M” key is pressed again; the
“M+” changes back to “m+” and the new entry is stored in memory.
If the user plans to make any changes to system parameters, the first item that should be verified
or entered is the appropriate password for the security level required for the parameters to be
modified. Security level 2 enables modification of all variable system parameters, level 1
permits modification of some parameters; no security is required for viewing status items. The
security level password is entered through the “PIN” screen. If no front panel keys are pressed
for 60 minutes, the active
display. Pressing any key returns the display to normal; the password must be re-entered if
system parameters require changes.
Eleven LEDs are provided on the front panel of the control unit to indicate system status. Three
LEDs grouped together vertically provide overall system status; they are “MAJOR”, “MINOR”,
and “NORMAL”, indicating the presence of a major alarm, a minor alarm, or normal operation.
The other eight LEDs correspond to the active state of each of the alarm output relays and are
labeled “ALM1”∙∙∙“ALM6”, “MIN”, and “MAJ”.
6.2 SNMP interface
In addition, the unit’s controller incorporates a 10-base T Ethernet connection to allow remote
access to the system signals, and remote control of certain aspects of its operation. APC’s
Manual #991-0181 in the form of a CDRom will allow users to set up interface with the user’s
Information Technology System. Simple Network Management Protocol (SNMP) version 1 is
supported along with telnet protocol.

6.3 External Alarm Inputs
The four external alarm inputs (also referred to as “Input Relay Alarms”) can be assigned a
priority and routed or “mapped” to alarm output relays. Available assignments are “Ignore”,
“Major”, “Minor”, and “Relay 1” ∙∙∙ “Relay 6”. Screens for making the assignments are
located at [SYSTEM/IN-RLY/RLY-MAP]. A user defined name or “alias” may also be
assigned to each of these input alarms. Screens for making these assignments are located at
[SYSTEM/IN-RLY/ALIAS]. For information on wiring connections to these inputs refer to
Section 5.6.1.
6.4 Alarm Output Relays
There are eight alarm output relays designated Relay 1 through Relay 6, Minor, and Major,
respectively. Various system parameters may be programmed to activate any of these alarm
relays when set thresholds are exceeded or specific conditions occur. The first six relays can
also be assigned a priority and routed or “mapped” to other output alarm relays. Available
assignments are “Ignore”, “Major”, “Minor”, and “Relay 1” ∙∙∙ “Relay 6”. Screens for making
these assignments are located at [SYSTEM/OUT-RLY/RLY-MAP]. This feature makes it
possible for a single alarm condition to activate multiple alarm output relays including the Minor
or Major alarm relay. A user defined name or “alias” may also be assigned to each of the eight
output relay alarms. Screens for making these assignments are located at [SYSTEM/OUT-
RLY/ALIAS]. For information on making wiring connections to the alarm output relays refer
to Section 5.6.2.
6.5 Parameter Locations, Descriptions, and Default Values
The location, description, and factory programmed default value for each of the MX28B600
system parameters is found in 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:
[SYSTEM/IN-RLY/RLY-MAP]. To find the parameters that can be accessed in this category,
starting from the main menu screen, do the following:
1) Use the right or left arrow keys to position the cycling cursor below “SYSTEM”.
2) Press the down arrow key once.
3) Use the right arrow key to position the cycling cursor below “IN-RLY”.
4) Press the down arrow key once; the cursor will be cycling below “RLY-MAP”.
5) Press the down arrow key (repeatedly if necessary) until the desired parameter screen is
displayed (there are eight parameter screens in this category).
6) After making any desired changes (refer to Section 6.1 for the procedure), to return to the
main menu press the up arrow key repeatedly.
If a parameter requires a level 1 or level 2 security access to permit changes to it, the security
level will be found in braces, i.e. {2}, in the “PARAMETER” column of table 6.4.1.
The complete menu structure shown in the order in which it is accessed from the control unit
display is presented in outline form in figure 6.4-1 Each indentation to the right represents a
