• 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 MX28B 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. 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 be wrapped in electrical tape or otherwise insulated.
5.1.5 Room/Locations
NOTE: The Advance Power, Inc. Model MX28B 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 NEC or the 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 for
all other equipment that may reside in the power room area.
12 MX28B
Page 17
5.1.6 Mounting
Both front mounting on standard 23-inch rails and optional wall mounting are available.
5.1.7 Ventilation
The rectifiers have fans that provide front to rear airflow for internal cooling. The MX28B
housing should 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 MX28B 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 right rear of the MX28B housing, is provided with
two one-inch conduit entry holes and an access cover. Inside, a terminal strip(s) for ac
input power connection and a separate “Earth Ground” bar for connection of the safety
ground wire(s) are provided. The terminal block(s) is labeled as Position 1 through Position
4 (Position 1 through Position 8 for the 400-amp unit) with each position having inputs
designated “L1” and “L2” for connection of the two ac wires. Positions 1-4 correspond to
the top rectifier shelf positions from left to right. Positions 5-8 are applicable to the 400-amp
unit only and correspond to the lower 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
5.3.1 Battery Disconnect
An external circuit breaker (not supplied) is required in the negative line (located at the
battery end) to protect the cables from the battery to the MX28B dc power plant. The power
plant can monitor auxiliary contacts from this breaker.
5.3.2 Cable Sizing Considerations
The battery cable(s) should be sized sufficiently large to limit the voltage drop from the
MX28B dc power plant to the battery during charging per system design requirements. The
MX28B 13
Page 18
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 Advance Power, Inc.
5.3.3 Connecting the Cables
The battery cable connections are located at the top 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
Model MX28B 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 LEFT END 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 PLAN.
5.5 Rectifier Installation
The Advance Power, 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) Remove the rectifier retaining screw from the shelf position where the rectifier is to
be installed.
3) Slide the rectifier into the shelf between the guides until it is fully seated.
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.
5.6 Alarm Connections
The alarm connections for all rectifiers, breakers, and fuses are factory pre-wired. The
MX28B dc power plant, however, permits the user to program the system alarms in various
ways.
5.6.1 External Alarm Inputs
Four external alarm inputs with assignable priority levels are available. These alarm inputs
respond to external dry contact closures between normally open (NO) and common (C) or
contact openings between normally closed (NC) and C (see Table 5.6-1).

5.6.2 Alarm Outputs
There are eight alarms available that provide outputs via Form “C” relay contacts. The last
two of these are preassigned as the Minor and Major alarm outputs. The Major relay is
energized (NO-C contacts closed) during normal (non-alarm) operating conditions; all the
other relays energize when an alarm condition occurs. The other six outputs are initially
designated as “Relay 1” through “Relay 6” (the user may assign more meaningful names if
desired). The various system alarm conditions can be assigned to any of the eight alarm
outputs.
Table 5.6-3 shows the alarm output connection designations. Connectors J1 and J2 are
located on the interface card mounted in the top left side of the unit. The relay contacts

Page 22
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 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 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 return bus located just above and rearward of the breaker connection points
18 MX28B
Page 23
as seen in Figure 5.7-1. The return bus provides 24 sets of threaded #10-32 holes on 5/8”
centers and four sets of threaded ¼”-20 holes on ¾” centers for connection of two-hole lugs
on load return wires.
5.7.3.2 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.
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:
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 MX28B 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 MX28B 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 MX28B
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 = 12A. (Bellcore specifications
recommend a maximum charging rate of capacity (in Ampere-hours) divided by 20
hours; check the 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 MX28B 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 MX28B
dc power plant.
2) Turn on the external circuit breaker from the battery to the power plant.
3) Turn on all the circuit breakers that supply ac power to the rectifiers in the MX28B
dc power plant.
4) Load circuit breakers may now be turned on as required.

6. SETUP, ADJUSTMENTS, AND OPERATION
6.1 User Interface
The MX28B control unit provides a user interface designed with a hierarchical menu that
can be viewed on the 32-character display by “navigating” with the “ï” (left), “ð” (right), “ñ”
(up), and “ò” (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 can not be modified. When ac power is initially applied,
there is a 60-second 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 password reverts to “0000” and
“ADVANCE” begins to move about the 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 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.
MX28B 21
Page 26
6.3 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.
6.4 Parameter Locations, Descriptions, and Default Values
The location, description, and factory programmed default value for each of the MX28B
system parameters is found in Table 6.4.1. 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 menu level below the indicated title.
