1.3 Power Module Part Numbers SB3000 Power Module part numbers are organized by the number of cabinet bays, i.e., single (445A), double (890A), or triple (1335A) cabinet bay configurations, in combination with the supplied options. See figure 1.1.
1.4 Related Publications This manual describes the hardware components of the SB3000 Power Module. Refer to the publications listed below for detailed descriptions of the remaining components of the SB3000 system and the configuration and programming necessary to control the SB3000 Power Modules.
CHAPTER 2 Mechanical/Electrical Description This chapter provides an overview the SB3000 Power Module’s main components and their mechanical and electrical characteristics. The SB3000 theory of operation is described in Appendix B. 2.1 Mechanical Description High Power SB3000 Power Modules are housed in protective sheet metal enclosures, as shown in figures 2.1 to 2.3. The Power Modules come in single, double, and triple bay cabinet configurations, depending upon the current rating. See figures 3.1 to 3.
Local Power Interface module (LPI) The LPI module is the interface between the SB3000 Power Module and the PMI rack. It is through this module that information is sent to the SB3000 Power Module and feedback data is sent back to the PMI rack. Capacitor Bank Assembly The capacitor bank's electrolytic capacitors store DC power from the IGBTs.

2.2 Electrical Description AC power to the SB3000 Power Module is supplied from an AC power distribution/ soft-charge cabinet through the AC input reactor. ! ATTENTION: DC bus capacitors retain hazardous voltages after input power has been disconnected. After disconnecting input power, wait ten (10) minutes for the DC bus capacitors to discharge.
When the DC bus operating voltage is reached, the connected inverter power modules may be operated. Note that an SB3000 Power Module cannot support the loading of SA3000/SA3100 Power Modules when the soft-charge resistors are limiting the bus charging current. ! ATTENTION: SA3000/SA3100 Power Modules must be in standby or in regeneration whenever the SB3000 Power Module’ s pre-charge contactor opens. The SB3000 Power Module’s soft-charge resistors may fail if this interlocking restriction is not observed.

CHAPTER 3 Installation Guidelines This chapter provides guidelines and wiring recommendations to be followed when installing SB3000 Power Modules. Hardware installation of the 445A, 890A, and 1335A units is covered. Please refer to the appropriate SA3000/SA3100 instruction manual for information on properly connecting your AC inverter power module to the SB3000 DC bus output. ! 3.1 ATTENTION: The user is responsible for conforming with all applicable local, national, and international codes.
3.2 Wiring ATTENTION: The user is responsible for conforming with all applicable local, national, and international codes. Failure to observe this precaution could result in damage to, or destruction of, the equipment. ! System wiring is to be done according to the supplied wiring diagrams (W/Es), which are application-specific. Sections 3.2.1 through 3.2.6 provide additional information on input fuses, pre-charge components, AC line reactors, and recommended wire types. 3.2.

! ATTENTION: The SB3000 Power Module may cause a large variation in the input isolation transformer’s neutral-to-ground voltage in ungrounded and high-resistance grounded systems. This type of high frequency, high level line disturbance may cause improper ground fault detector operation or component failure. Failure to observe this precaution could result in damage to, or destruction of the equipment.
3.2.6 Wire Routing AC input wiring is routed through the top of the cabinet, above AC line terminals 181, 182 and 183. DC output wiring is also routed through the top of the cabinet. DC output wiring is usually connected directly to the DC bus in the overhead enclosure that distributes the DC power to common DC bus SA3000/SA3100 Inverter Power Modules. The AC power distribution cabinet is mounted separately from the SB3000 Power Module but should be positioned conveniently close by.

CHAPTER 4 Diagnostics and Troubleshooting This chapter describes the equipment needed to check the operation of the SB3000 Power Module and the tests to be performed. Included are descriptions of the SB3000 Power Module faults and warnings monitored by the Distributed Power System software. Procedures are also provided for replacing Power Module cabinets, sub-assemblies, and fuses. ! ATTENTION: DC bus capacitors retain hazardous voltages after input power has been disconnected.
! ATTENTION: The Power Module is not isolated from earth ground. AC line powered test instruments used to measure Power Module signals must be isolated from ground through an isolation transformer. This is not necessary for battery-powered test instruments. Failure to observe this precaution could result in bodily injury.

4.3.1 Faults The following faults will cause the SB3000 Synchronous Rectifier to shut down. See table 4.3. In a fault situation, the PMI Processor will command zero current and will stop firing the Power Modules’ IGBTs; however, the IGBT emitter-collector diodes will supply rectified line voltage to the DC bus until AC input power is disconnected. Faults must be reset before the SB3000 Synchronous Rectifier can be restarted. Table 4.

4.4.2 Replacing an IGBT Phase Module Assembly Important: When replacing an IGBT phase module assembly be sure to re-install, position, and tighten the hardware in the proper sequence. The IGBT phase module must be aligned correctly to prevent damage to the components. If all three IGBT phase modules are to be replaced, it will be easier to remove them by starting at the top and working down, i.e., begin by removing module U, continue with module V, and then finish by removing module W.
Step 11. Start and finger-tighten the two M6 hex nuts on the negative bus bar. See figure 4.7, callout 4. Step 12. Start and finger-tighten the two 5/16” cap screws, flat washers, and lock washers on the heatsink. One cap screw is located on each side of the heatsink. See figure 4.7, callout 5. Step 13. Start and finger-tighten the two M8 bolts on the AC bus bar. See figure 4.7, callout 3. Tighten the bolts evenly. Step 14. Loosen the M8 bolt on the left side of the fuse. See figure 4.7, callout 1.

4.4.3 Replacing a Blower Assembly Use the following procedure to replace a blower assembly: Step 1. Turn off and lock out the AC input power. Step 2. Wait ten minutes to allow the DC bus voltage to dissipate. ! ATTENTION: DC bus capacitors retain hazardous voltages after input power has been disconnected. After disconnecting input power, wait ten (10) minutes for the DC bus capacitors to discharge.
Step 3. Open the cabinet doors and check the voltage across the DC bus bars, 347 A,B,C (+ bus) and 345 A,B,C (- bus), with an external voltmeter to ensure the DC bus capacitors are discharged before touching any internal components. See figure 4.1. Step 4. Remove all three IGBT assemblies (U, V, and W). Refer to section 4.4.2 for information on IGBT assembly removal. Step 5. Remove the AC input power wiring by removing the bolt from the LEM stud spacer.
Step 4. Disconnect the AC input leads from terminals 181 (L1), 182 (L2), and 183 (L3). Disconnect the GND wire from the ground terminal. See figure 3.4. Step 5. Disconnect the AC input line (two-wire 115 VAC with ground) from the L1 (L), L2 (N), and GND terminals on the control power board. See figure 3.4. Step 6. Disconnect the DC bus from terminals 45 and 47. See figure 3.4. Step 7. Remove the SB3000 Power Module cabinet. Step 8.

APPENDIX B Theory of Operation B.1 Typical SB3000 System SB3000 Power Modules are used to supply regulated common DC bus power to one or more SA3000/SA3100 Power Modules. As illustrated in figure B.
Figure B.
B.2 SB3000 Regulator The main purpose of the SB3000 regulator is to maintain the proper voltage on the DC bus through the use of a vector algorithm executed in the PMI Processor. The application task in the UDC module controlling the SB3000 Power Module passes the desired DC bus voltage reference command to the PMI Processor in register 102/1102. The PMI Processor uses proportional-integral-derivative (PID) logic to calculate DC bus current in response to the voltage reference and error values.

B.2.1 Leading Power Factor Operation The regulator has the capability to operate with a leading power factor. This allows the regulator to calculate the Id current based on the capacity that is left over in the SB3000 Power Module rating after the Iq current has been determined.
B.3 SB3000 DC Bus Charging Sequence The SB3000 pre-charge circuitry is controlled via a pre-charge contactor which is under the control of the PMI Processor in the SB3000 PMI rack. Any faults relating to pre-charge contactor operation are reported in registers 202/1202 and 205/1205. The closing and opening of the pre-charge contactor is a function of the measured DC bus voltage. See figure B.4.
B.3.3 Pre-charge Contactor’s Close Threshold Voltage When control power is first turned on, the pre-charge contactor will be open. This allows the DC bus voltage to increase to near the peak voltage of the AC line. The pre-charge contactor’s close threshold voltage is equal to the following: Close Threshold Voltage = 1.414 x (Peak Configured AC RMS Line Voltage) - 10% This threshold voltage allows the SB3000 Power Module to turn on when the AC line is up to 10% low.

B.3.5 Pre-charge Contactor Sequencing During the Bridge Test When the bridge test is commanded in register 100/1100, bit 2, the SB3000’s pre-charge contactor will close. After the results of the test have been displayed on the GDI module(s), the pre-charge contactor will be opened. B.3.6 Charge Faults The PMI Processor will generate a Charge Fault (register 202/1202, bit 6) if: • the pre-charge contactor is closed when it should be open. • the pre-charge contactor opens without being commanded to open.

APPENDIX C SB3000 Interlock Sequencing When a request is made to turn on the SB3000 Power Module’s voltage loop and a required precondition has not been met, a bit will be set in Interlock register 205/1205 indicating the problem. The interlock requirements are described in the following table. If an interlock problem is detected, the voltage loop will not go into run.
C-2 SB3000 Power Modules (RCS)
APPENDIX D Performing the Bridge Test Important: This test is normally performed at the factory. It should not be necessary to perform it again unless the power devices or fiber-optic cables have been replaced. The bridge test is used to verify fiber-optic gate cabling connections by test firing the IGBTs one at a time. As the IGBTs fire, the LEDs on the corresponding GDI module in the PMI rack will turn on and off in the following sequence: 1. U- (Lower Power Device) 2. U+ (Upper Power Device) 3.
Use the following procedure to perform the bridge test: Step 1. Disconnect, lockout, and tag the three-phase AC input power to the SB3000 Power Module. Step 2. Ensure that the DC bus is fully discharged. Refer to section 4.2 of this manual. Step 3. Enable the bridge test through register 100/1100, bit 2, and bits 10, 11, or 12, as applicable. Step 4. Verify that the LEDs turn on and off in the order described.
