Important User Information

Solid state equipment has operational characteristics differing from those of

electromechanical equipment. Safety Guidelines for the Application, Installation and

Maintenance of Solid State Controls (Publication SGI-1.1 available from your local

Rockwell Automation sales office or online at http://www.ab.com/manuals/gi)

describes some important differences between solid state equipment and hard-wired

electromechanical devices. Because of this difference, and also because of the wide

variety of uses for solid state equipment, all persons responsible for applying this

equipment must satisfy themselves that each intended application of this equipment is

acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for indirect or

consequential damages resulting from the use or application of this equipment.

The examples and diagrams in this manual are included solely for illustrative purposes.

Because of the many variables and requirements associated with any particular

installation, Rockwell Automation, Inc. cannot assume responsibility or liability for

actual use based on the examples and diagrams.

No patent liability is assumed by Rockwell Automation, Inc. with respect to use of

information, circuits, equipment, or software described in this manual.

Purchased Components and

Additional Instruction

Sheets

Manuals and datasheets for specific components inside the motor control

center (transformers, metering devices, electronic overloads, PLCs, soft

starters, drives, etc.) are shipped inside the motor control center. These

manuals and data sheets must be read and understood before installing and

operating the motor control center. Keep these manuals and other

documentation for future reference.

Definitions

Column –Vertical segment of a motor control center. Columns consist of the

bus system, units and wireways. Sometimes referred to as cubicle.

Conduit – Metal tube that encloses electric wires and cables.

Control station –Door mounted assembly that houses pushbuttons, indicator

lights and other small control devices.

Control unit – Unit that contains any type of power control or metering

device including starters, contactors, AC drives and soft starters.

Disconnected position – Plug-in unit operating position in which line, load,

control, network, and Protective Earth (PE) connections are disengaged, but

the unit is still housed in the column. For more information refer to Chapter 6 –

Unit Information.

Double-front – Configuration in which columns are installed back-to-back.

Columns with double-front construction contain separate power bus systems

that are spliced together. (Figure 1.5)

Feeder unit – Unit containing a disconnection means used to distribute power

to a remote device. Available in two types: circuit breaker or fused disconnect.

Publication Title Publication Number(1)

Fixed unit – Unit that is permanently mounted in a column. These units

typically house components that are large and/or require more current

capacity than a plug-in unit can provide. Sometimes referred to as a

frame-mounted unit.

Inserted position – Plug-in unit operating position in which the line, load,

control, network, and Protective Earth (PE) connections are engaged. For

more information refer to Chapter 6 – Unit Information.

Locking mechanism – Part of the withdraw lever. This mechanism must be

engaged to select unit operating positions. (Figure 6.10)

Main switch – Disconnecting means for a Motor Control Center. Available in

two types: circuit breaker or fused disconnect.

Module space – Grid size used to determine space distribution within the

motor control center. Height of one module is approximately 80 mm. Module

width is 500 mm.

Motor Control Center (MCC) – One or more columns operating with a

common power bus.

PFCC – Power factor correction capacitor.

Plating – Type of surface treatment that distributes a layer of protective

coating on structural parts.

Plug-in units – Replacable units with line connections made via unit bus line

stabs. Plug-in units include withdrawable units. Sometimes referred to as

withdrawable or removable units.

Protective earth conductor (PE) – Protective circuit busbar. Sometimes

referred to as earth bar.

Shipping block – Also referred to as shipping splits. Two double-front or 700

mm columns joined together at the manufacturing site for ease of

transportation. Shipping blocks cannot be separated at the installation site. A

shipping block can also be one section.

Skilled person – “Person with relevant education and experience to enable

him or her to perceive risks and to avoid hazards which operation or

maintenance of a product can create.” IEC 60204-1, 3.52 and IEV 195-04-01.

Stabs – Assembly located on the back of a unit that is used to make line and

load connections. (Figures 6.3 and 6.4)

Test position – Plug-in unit operating position in which the control, network,

and Protective Earth (PE) connections are engaged, and line and load

connections are isolated. For more information refer to Chapter 6 – Unit

Information.

Publication 2500-IN001A-EN-P - May 2006

iii

Trunk line – Main DeviceNet communication cable within the motor control

center.

Unit – An arrangement of power and/or control devices that are housed

together and inserted into a column. A unit may be used to distribute power or

control a remote device. The size of units is described by module space.

Unit main switch – Disconnecting means for a unit within a motor control

center. Available in two types: circuit breaker or fused disconnect.

Withdraw lever – Mechanism used to insert and remove withdrawable units.

The withdraw lever is used to select an operating position (inserted, test,

disconnected, and withdrawn) and has mechanical detents to ensure that the

lever is securely in position. (Figure 6.10)

Withdrawable unit – Unit where line, load, control, network and PE

connections are made using stabs or connectors. Withdrawable units are

inserted and removed using the withdraw lever.

Withdrawn position – Plug-in unit operating position in which line, load,

control, network, and Protective Earth (PE) connections are disengaged and

the unit is removed from the column. For more information refer to Chapter 6

– Unit Information.
