MX28B600-48V 4.2 Power Output Capacity 600 amps maximum, or 550 amps with N+1 redundancy. The housing provides space for three rectifier shelves that can hold up to four rectifiers each, a control unit, and two tiers of up to 43 distribution circuit breakers. 4.3 Rectifiers The rectifiers are APC DC Network Solutions, Inc. Model MRF28H54BV with specifications as follows: • Input Voltage: 176-264V AC (230V AC nominal) @ 45-66 Hz • Input Current per Rectifier: 13.
MX28B600-48V 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. There are three entry points (one for each rectifier shelf), for customer-supplied one-inch conduit. Section 5.2 for details on electrical connection. 4.6 Battery connections Battery connections are made by feeding the cables thru the bottom-rear of the unit. Use caution when running the cables to not damage other components. (Figure 4.6-1).
MX28B600-48V 4.7 DC Distribution Two plug-in circuit breaker tiers, consisting of a 24-position panel and two 10-position panels, provide 43 positions of -48V distribution. One position is reserved for the Manual Battery Disconnect Switch. The breaker tiers are center fed via bus bars to the -48V DC bus with each side having 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.

MX28B600-48V 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.
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.
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.
MX28B600-48V Figure 5.6 Interface Board 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). 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.
MX28B600-48V 5.6.2 Alarm Outputs There are eight alarms available that provide outputs via Form “C” relay contacts. The last two of these are pre-assigned 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 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.
MX28B600-48V 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.

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.
MX28B600-48V 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].
