system. Failure to comply can result in personal injury
and/or equipment damage.

ATTENTION: Verify that all sources of AC and DC
power are deenergized and locked out or tagged out in
accordance with the requirements of ANSI/NFPA 70E,
Part II.

ATTENTION: The system may contain stored ener gy
devices. To avoid the hazard of electric al shock, ve rify
that all voltage on capacitors has b een discharge d before
attempting to service, repair, or remove a drive system
or its components. You shou ld only at tempt the
procedures in this manual if you are qualified to do so
and are familiar with solid-state control equipment a nd
the safety procedures in ANSI/NFPA 70E.

ATTENTION: An incorrectly applied o r incorrectly
installed drive sys tem can result in component damage
and/or a reduction in product life . Wiring or applicati on

errors–such as undersizing the motor, incorrect or
inadequate AC supply, and excessive ambient
temperatures–can r esult in the malfunction of hte drive
equipment.

A TTENTION: This dr ive system contains parts and
assemblies that are sensitive to ESD (electrostatic
discharge). Sta tic control precautions are requir ed when
installing, testing, or repairing this assembly.
Component damage can r esult if ESD cont rol procedures
are not followed. If you are not familiar with static
control procedures, refe r to Rockwell Automation

1-12 Product Overview

Power Components This section will break down and define the incoming power,

armature power, and field supply components.

Incoming Power Components

Incoming Devices

The 1250 and 1650A DC drives a re intended to be used straight from
the customer- supplied, power controlled incoming lines, without any
additional isolation transformer or line chokes (however, adding
either of these would increa se isolation to other equipment on the
power lines).

The 3000A DC drive does not require an isolation transformer or line
reactors if it is the only eq uipment on the power lines. However, if it
shares power with ot her equipm ent on th e same power lines, it will be
necessary to use eithe r line reactors or an isolation transformer ahead
of the drive.

The system designer needs to provide proper circuit impedence to
limit the sho rt circui t c urrents according t o the break er derat ing cha rts
given in Appendix A.

Some drives may require an output inductor in serie s with the
armature, especially for older machines which do not have enough
internal inductance for a proper armature commutation process.

AC Input Busbars

Tin plated busbars are supplied for all input connections through the
top of the disconnect bay. Busbar dimension dia grams are given in
Appendix A.

Main Disconnect (Optional)

A 3-phase circuit breaker can be supplied on the incoming line for
each high-horsepower drive. Appendix A lists circuit breaker
specifications, and shows diagrams of the circuit breakers settings for
the 1250, 1650, and 3000A DC drives.

AC Line Fuses (Optional)

AC line fuses can be supplied for the 3-phase incoming power.

Note: Units require either a main disconnect or AC line fuses.

Publication 2361-5.01 July 1998

Product Overview 1-13

Control and Field Power

The first (L1) an d thir d (L3 ) pha s e of the inco m ing p ow er are t app ed
off and fused to provide single-phase AC power to the primary of
control power t ransformer (115V AC), field supply circuit (460V AC
maximum), and 24V DC power supply.

Note: For drives using a 575 or 660V AC input, a step-down
transformer will be required for the field supply circuit (see
Figur e 1. 12).

AC Line RC Suppressor (Optional)

The optional AC line RC suppressor is a device used for limiting line
voltage spikes in drives when the medium volta ge source to the
primary of the distribution transformer is switched. The option is
offered for a dist ri bution transformer primary voltage of 2300V or
greater.

Publication 2361-5.01 July 1998

Armature Power Components

The armature power components work together to convert the 3­phase AC input to a DC output used for powering your motor
armature.

The following items make up the armature power circuitry:

• armature bridge (and its subordinate components)

• cell fuses

• gate board s

• DC contactor

Armature Bridge

The armature bridge is design ed to convert incoming AC power to
DC power. The non-regenerative bridge is shown in Figure 1.9. Cell
fuses protect the thyristors in the event of a bridge failure.

The 3000A unit uses solid core (ferrite)
chokes on the AC line.

Silicon-Controlled Rectifiers (SCRs)

Each drive uses silicon-c ontrolled rectifiers (SCRs) in the thyristor
bridge to switch the incoming 3-phase AC power to DC output
power.

These SCRs allow current to flow from anode to cathode when two
conditions are met. First, like a diode, it must be forward biased.
Second, an appropriate pulse must be applied to the gate (through the
pulse transformer board).

The current will continue thr ough the SCR until the voltage across it
reverses and the current drops to zero (called line commutation).
Figure 1.11 shows a picture of an SCR, depicting its polarity.

Publication 2361-5.01 July 1998

1-16 Product Overview

Silicon-Co ntrolled Rectifier
(SCR )

Snubbers

Snubbers (resistor/capacitor assemblies) are installed in para llel with
the SCRs, working with the cell reactors to provide adequate voltag e
suppression when the SCRs switch off.

Armatur e-Pulse Transformer Boards

Armature-pulse transformer boards provide the appropriate gate
voltage and current to trigger an SC R. In addition, these boards
provide gate driver isolation from the control logic. Figure 1.11
shows an armature-pulse tr ans former board.

DC Contactor

The main DC contactor is used to break the DC current to the motor
armature. Coil voltage to the con tacto r is controll ed by contacts from
the pilot relay.

Field Power Components

The field power components work together to convert single-phase
AC power to a DC output used for powering your motor field.

The following items make up the field power circuitry:

• field bridge

• field-pulse tra nsformer board

In addition, fuses, meta l- oxide varistors (MOVs), and an induc tor, as
shown in Figure 1.12, are used to pr otect the field bridge from
extreme curre nt and voltage conditions. The field circuitry is fan­cooled.

Note: The field power components are rated for voltages up to
460V AC. Drives with input voltages of 575 or 660V AC use a
single-phase fie ld transformer (PT5) to step down the voltage to
460V AC. PT5, shown in Figure 1.12, is connected at the
customer site.

Field Bridge

The field bridge uses four SCRs to convert the single-phase AC
power into a DC output. For the SCRs to conduct, they must be
forward biase d and have a pulse applied to the ir gates. The SCR gate
is enabled by the field-pulse tr ansformer board.

Field-Pulse Transformer Board

The field-pulse tranformer board provides the necessary gate volta ge
and current to trigger the SCRs on. This board uses a resistor/
capacitor arrange ment to protect the SCRs from rapid voltage
changes.

Conclusion 2-8

Introduction Your 1250A DC drive functions with the following features:

• The 1250A drive uses twelve SCRs (regenerative) or six SCRs
(non-regenerative) in the armature bridge to convert the 3-phase
AC input to a DC output. The SCRs are built into a heatsink
assembly and are cooled by the bridge fan.

• The 1250A drive is protected from incoming fault curr ents with a
circuit bre aker. The components of your drive (the armature
bridge, field bridge, and control components) are protected with
fuses, MOVs, snubbers, and/or chokes.

• The 1250A drive is cons tructed and housed in thr ee bays, the f irst
bay containing the AC input and control hardwa re, the second
bay containing the armature bri dge hardware, and the third bay
containing the DC output hardware.

• The 1250A drive has an optional top-hat extension available for
the AC input bay.

• The 1250A drive can be built with an optional through bus
assembly, allowing the 1250A drive and other connected drives
to tap off from the same AC input.

your 1650A Bulletin 1395 DC drive. The following topic s will be
covered in this chapter:

Symbol Reference Chart 3-6
Drive Structure 3-8
Conclusion 3-8

Introduction Your 1650A DC drive functions with the following features:

• The 1650A drive uses twelve SCRs (regenerative) or six SCRs
(non-regenerative) in the armature bridge to convert the 3-phase
AC input to a DC output. The SCRs are built into a heatsink
assembly and are cooled by the bridge fan.

• The 1650A drive is protected from incoming fault curr ents with a
circuit breaker, and the DC output is protected from faul t currents
with a DC contactor. The components of your drive (the
armature bridge, field bridge, and control components) are
guarded with fuses, MOVs, snubbers, and/or chokes.

• The 1650A drive is cons tructed and housed in thr ee bays, the f irst
bay containing the AC input and control hardwa re, the second
bay containing the armature bri dge hardware, and the third bay
containing the DC output hardware.

• The 1650A drive has an optional top-hat extension available for
the AC input bay.

• The 1650A drive can be built with an optional through bus
assembly, allowing the 1650A drive and other connected drives
to tap off from the same AC input.

Conclusion 4-8

Introduction Your 3000A DC drive functions with the following features:

• The 3000A drive uses twelve SCRs in the armature bridge to
convert the 3-phase AC input to a DC output, six for the posi tive
DC output and six for the negative. The SCRs are built into a
heatpipe asse mbly and are cooled by the bridge fan.

• The 3000A drive is protected from incoming fault curr ents with a
circuit breaker, and the DC output is protected from faul t currents
with a DC contactor. The components of your drive (the
armature bridge, field bridge, and control components) are
protected with fuses, MOVs, snubbers, and/or chokes.

• The 3000A drive is construct ed and house d in four bays, the first
bay containing the AC input and control hardwa re, the second
bay containing the fuses, the third bay containing the armatu re
bridge hardware, and the fourth bay containing the DC output
hardware.

• The 3000A drive has a standard top-hat extension over the
disconnect bay for the AC input.

5-2 Installing Your Drive

Physically Installing the Drive
at Your Site

&

T o move and posit ion the unit a t your site, you will ne ed to follow the
instructions given in Publication 2100-5.5, titled Receiving,
Handling, And Storing Motor Control Cente rs–Instructions. This
publication will instruct you in the proper handling, moving, a nd
positioning of your new drive.

&

After the drive is properly positioned, follow the instructions given in
Publication 2300-5.1, titled Bulletin 2300 Family of Drive Systems
Hardware–Installation Manual. This publication will teach you how
to splice busbars, how to attach your unit in a multiple drive
configuration , and how to join MCC sections together (if necessary) .

Inspecting the Air Baffles

Inspect the air ba ffles and guar d s acc ord i ng to the air baffl e layouts
shown in Appendix A.

Preparing AC Input Entry If your drive ha s an extra input bay installed, you can skip this

section.

To prepare input entry, select the ideal hole placement (within the
constraints of the fol lowing dia gram), then follow the installation
steps given. The following instr uctions include directions for a top
hat assembly.

Note: When pre paring the input entry, you may need to consider
the busbar arrangement and the wir e size s. Busbar diagrams are
shown in Appendix A, and recommended wire sizes are listed
later in this chapter.

Installing Your Drive 5-3

1. Remove the lifting angle, if it is still attached.

2. Remove the top plate from the disconnect bay. If the drive has a

top hat assembly, this plate will not be needed.

3. If the drive has a top hat assembly, mount the assembly to the

drive (accor ding to the assembly instructions), and remove the

assembly’s top plate.

ATTENTION: The top plate must be removed from
the drive before any cutting, drilling, tapping, or welding

!

4. Punch holes for the AC input into the top plate within the area

shown in Figure 5.1. Clean the punched area to ensure that metal
shavings will not fall into the dri ve.

5. Secure the top plate to the drive (or top hat assembly), and

replace the lifting a ngle.

Installing the Field Transformer

1. Mount the transformer enclosure and re move any input/output

knockouts, as necessary (see Figure 5.4 for enclosure detai ls).

2. Ground the enclosure according to local codes.

3. Remove the top plate from the enclosure.

4. Connect the first and third phases to the transformer primary

(F20 to H1, F21 to H2).

AT TENTION: The motor field supply is phase
sensitive. To guard against possible drive or motor

!

damage, ensure that t he connections are made accord ing
to Figure 5.3.

5. Wir e the secondary back to drive TB8 (X1 to TB8-1, X2 to

TB8-3).

6. Secure the top plate on the e nclosure.

Determining Catalog Numbers

To help you to understand, we will provide an example of how to
determine a catalog number for a DC drive.

The beginning portion of the cata log number for high-horsepower
1395 DC drive units would be 2361E or 2361F (E for regenerative,
F for non- regenerati ve). The remai ning por tio n of the c atalog n umber
will represent the opti ons fo r which you need to make a selec tion.

The catalog number must appear in this orde r:

Module

Size

Enclosure

AC Input Line

HP

Trip Device Options

B-2 Catalog Numbers and Spare Parts Kits

For example, if you were to use the table on the following pa ge to
select a drive that:

• is a regene rative unit

• supplies 1000 HP

• 3-phase AC input of 460V AC

• has a NEMA Type 1 enclosure without gaskets and door fan
filters

• has a high instantaneous trip circuit breaker

• includes the options:

• ControlNet™ communication boa rd

• 115V AC discret e adapter board

• emergency stop

The catalog number would be:

2361EA-SAB-68CM-14CN-14DAA-1B



Units accommodate top entry and bottom exit. An additional section is required for bottom entry and a separate additional
section is required for top exit.



Units configured for 575 or 660V AC inputs require field transformers. The field supply modules require an input voltage of
460V AC and the field transformer is utilized to step-down 575 or 660V AC inputs to 460V AC. The base unit price of a 575
or 660V AC input drive includes a field transformer (and fusing) that provides up to 18A to the field supply module. Select a
field transformer upgrade option when you need to supply more current to the field supply module. All field transformers
come standard in a NEMA Type 1 enclosure. Nominal field currents based on 85% efficiency, unit control power usage, and
a 300V field supply.
