1. GENERAL INFORMATION 1.1 Introduction DC Power Systems 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. All system settings are made from the system control unit that provides monitoring and control functions for each component of the system as well as alarm listings for system diagnosis and maintenance.

4. PRODUCT OVERVIEW AND TECHNICAL DESCRIPTION 4.1 Description The Advance Power, Inc. Model MX28B is a modular stand-alone -48V dc power plant. It is configurable in such a manner that it will support most typical applications within the specified current ranges (either 200 or 400 amperes) without special application engineering or assistance. Distribution is included for up to 24 plug-in circuit breakers.
Figure 4.1-2.
4.2 Power Output Capacity The power plant has two basic configurations: The first supplies a maximum of 200 amps or 150 amps with N+1 redundancy. The housing for this configuration provides space for one rectifier shelf that can hold up to four rectifiers, a control unit, and one tier of up to 24 distribution circuit breakers. The second supplies a maximum of 400 amps or 350 amps with N+1 redundancy.
• Control of either a battery or a load LVD 4.5 AC Input Power Each rectifier requires 208/220/240V ac, single-phase, 50/60 Hz, supplied through an external 20-amp two-pole breaker. A rear located enclosure, with two holes for customersupplied one-inch conduit entry, provides a terminal strip(s) for ac input power connection and a separate “Earth Ground” bar for connection of the safety ground wire(s). 4.
4.7 DC Distribution A standard 24-position plug-in circuit breaker tier provides -48V distribution. The breaker tier is connected at its center to the -48V dc bus, and each side has an ampacity of 300A. Connections for -48V dc loads, requiring standard #10-32 two-hole lugs on 5/8-inch centers, are located directly above the corresponding breaker. The load returns connect to the return bus, which accommodates 24 two-hole #10-32 lugs on 5/8-inch centers, and four two-hole ¼”-20 lugs on ¾-inch centers.

5. INSTALLATION PROCEDURES 5.1 Preparation 5.1.1 Recommended Tools • 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.
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.
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.
External Alarm Source (non-alarm state) Connect To Input Alarm Terminals OPEN CLOSED NO-C NC-C Table 5.6-1. External Alarm Input Definition Table 5.6-2 shows the external alarm input connection designations. Connector J4 is located on the interface card mounted in the top left side of the unit. Systems are shipped with jumper wires connecting each NC and corresponding C contact. A jumper wire should be removed only if the corresponding NC-C contacts are going to be used.

MX28B + STATUS ALARMS SYSTEM MODULES BATT PIN OEM Figure 5.9-1 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.
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.
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”.
