System Overview
CENTERLINE® 2500 motor control centers (MCCs) are designed for
applications
low-voltage motor
for tough
required.
The CENTERLINE power bus structure distributes line power throughout
the MCC via an isolated bus work structure. A standard, center-fed,
300 A vertical bus supplies power to units above and below the horizontal bus,
which results in an effective 600 A capacity and unrestricted unit arrangement.
An optional 600 A vertical bus provides an effective rating of 1200 A.
that must comply with international standards and practices for
control centers. The CENTERLINE 2500 MCC is ideal
industrial applications where uptime and ease of maintenance is
ArcShield Rating
The CENTERLINE MCC is also available with an ArcShield™ rating. This
rating includes arc-resistant features for enhanced protection if internal
arcing faults happen.
With the standard safety features of the CENTERLINE 2500 MCC, the
ArcShield option provides the following:
•Spring latches
• Reinforced structure
• Pressure relief vent system through the top of the enclosure

System Overview Chapter 1
IntelliCENTER Software
IntelliCENTER MCCs can be provided with preconfigured IntelliCENTER
software. This software views, manages, and configures multiple MCC
lineups. The IntelliCENTER software communication driver lets the software
be installed and operated on EtherNet/IP or DeviceNet. The IntelliCENTER
software can function as a standalone software package or as an ActiveX
control in a Human Machine Interface (HMI).
Structure
CENTERLINE 2500 MCCs offer units with a full complement of
AC drives, soft starters, and other devices. Pluggable power connections on
the back of the unit plug into the vertical bus. A mechanical interlock helps
prevent the unit door from being opened while the main switch is in the
ON/I position. An additional mechanical interlock helps prevent the unit
from being withdrawn or inserted when the unit main switch is closed.
Separate vertical wireways isolate control and network cables from power
wiring. Units are available as fixed or fully withdrawable.

MCC Column-number Sequence
IMPORTANT CENTERLINE 2500 MCCs are designed to function in any column-number
sequence. However, we recommend that columns be installed in
sequential order.
Each CENTERLINE 2500 MCC column nameplate identifies columnnumber sequence, for example, MCC column 1 of 1 or 1 of 5. See
Figure 6 on page 16
Columns are numbered to match factory-supplied MCC elevation drawings
and to easily identify MCC columns and units. If there are questions about
column numbering during field installation, inspection, or operation, the
following instructions can provide guidance.
IMPORTANT Leftmost column must be installed in the proper location for the bus to
The most important criteria for additions of columns to existing MCCs is
matching the horizontal bus, enclosure type, and network capabilities for the
complete MCC line up. The voltage, current rating, short circuit withstand,
and IP rating for all columns must be consistent.

, for additional instructions.
Receiving
CENTERLINE 2500 MCCs are shipped upright as one or two column
shipping blocks or two or four double-front column shipping blocks. Each
CENTERLINE 2500 MCC shipping block is provided with a lifting angle.
Each column in a shipping block is bolted to the shipping skid with
removable shipping angles and covered with clear plastic wrap. Protection is
for upright shipping and is not waterproof or water-resistant. Equipment that
extends from the structures is also protected.
Heavy-duty export packaging is similar to standard packaging, but uses a
polywrap suitable for occasional water spray. In addition, wood framing and
sheeting surround the columns. The heavy-duty export packaging is not
water-resistant, waterproof, or intended for long-term storage.
Upon delivery of the MCC, see the packing slip shipped with your MCC for
sizes and exact shipping weights. Inspect the shipment for lost or damaged
items. If lost or damaged items are detected, see the steps that are described in
publication 2500-IN002

Handling
Storage
The following are acceptable methods of handling MCC columns within the
receiving facility. These methods are described in publication 2500-IN002
• Use of a forklift
• Overhead lifting (crane or hoist)
•Sling lifting
MCC columns must be handled in the upright vertical position. Failure to
comply with this method can lead to busbar, unit, and enclosure damage.
The MCC must remain bolted to the shipping skid until delivered to its final
installation area.
ATT EN TI ON : MCCs are top and front heavy. To avoid personal injury or
structural damage, never attempt to lift or move the MCC by any means
other than the methods outlined in Receiving, Handling, and Storing
CENTERLINE 2500 Motor Control Centers, publication 2500-IN002
Store CENTERLINE 2500 MCCs, units, and related equipment in
dry environment with ambient temperatures ranging from -25…+55 °C
(-13…131 °F). For short periods (<24 hours), temperatures of up to 70 °C
(158 °F) are allowed. Take care to help prevent damage from exposure to

Splice the Power Bus
ATT EN TI ON : To help prevent severe injury or death, de-energize all power
sources to the MCC before you join and splice columns. Follow EN 50110
requirements, and local codes and guidelines.
IMPORTANT When you splice the horizontal power bus, always begin by splicing from
the lowest phase busbar and work from the bottom up.
IMPORTANT NO-OX-ID Use– Do not get any busbar corrosion inhibitor on the bus
splicing hardware. It keeps the hardware from being properly torqued and
damage can occur.
Power bus consists of the main horizontal bus and neutral bus (if present).
Based on the current rating of the power bus, the splice kit contains the
appropriate splice bars and corresponding hardware. The following
procedures describe methods for splicing power buses that are based on the
ampere rating of the busbars.
For additional splicing information related to specific MCCs, see the
elevation drawing that is shipped with the MCC in the documentation
package.
TIP If necessary, remove units and unit support pans for the appropriate
access to splice the power bus.
Access the Power Bus
How to access the power bus depends on the column type. Follow the
procedures that are specific to your MCC columns.
For Columns with Main Units (see Figure 14 and Figure 15 on page 38)
1. Open the main unit door.
2. Depending on your unit, there are one or two splice covers with
handles to the side of the main, as shown in Figure 14
3. Remove the four M6 screws that secure each splice cover (step1 in

Install Cable
When you install cable, verify that it is installed according to appropriate
codes and standards. Multi-conductor cables, cable trays, cable ducts, and
conduit are all acceptable methods of routing cable to your MCC.
IMPORTANT All installed cable is installed must be compatible with the enclosure
rating of the MCC. Cable entry and exit points must be properly sealed so
water and moisture cannot enter or accumulate inside the enclosure.
Inside the MCC enclosure, route cable away from the PE conductor to avoid
damage. Position cable so bends are minimized and relative vertical
alignment to incoming connections is maintained. Final cable connections
must not place any additional strain on the termination blocks.
See the documentation package shipped with your MCC for the following
information:
• Approximate cable entry locations
• Space availability for incoming cables
•PE conductor locations
• Wiring schemes for main fusible disconnects, main circuit breake

Safety Guidelines to Install and Remove Withdrawable Units
ATT EN TI ON : De-energize, lock out, and tag out all sources of power to the
MCC when you install or remove MCC units. If MCC units are installed or
removed with power that is applied to the main power bus, follow
established electrical safety work practices. For further information, see
the publication, NFPA 70E: Standard for Electrical Safety in the
Wor kpl ace® .
ATTENTION: If power sources are connected to the motor control center,
use extreme caution when you insert units. All busbars and the line sides
of the inserted units are energized and contact with these parts can cause
injury or death.
ATT EN TI ON : To increase operator safety and help prevent equipment
damage, we recommend that two people install or remove units that are
in the upper six modules or over 1600 mm above floor level.
Units with door-mounted operator handles, switches, and disconnects must
be in the OFF/O position before units are inserted or removed.
Do not attempt to install or remove a unit when the unit main switch is in
the ON/I position.

22. Conduct an electrical insulation resistance test to verify MCC wiring
egrity. Conduct this test with an insulation resistance tester with a
int
potential of 500…1000 V.
ATTENTION: Verify that all switches or circuit breakers are in the
OPEN/I or Off/O positions before an electrical resistance test is
conducted.
Conduct this insulation resistance tester test phase-to-phase, phase-toPE and, when applicable, phase-to-neutral on the MCC bus work.
Typical insulation resistance values are 50 MΩ or greater.
Temperature, humidity, or dampness can affect insulation resistance
values and considerably lower insulation resistance readings. If the
insulation resistance values are less than 1 MΩ (due to dampness,
temperature, or humidity) or the MCC has been stored in a damp or
humid area, it is recommended the equipment be dried out. Dry out
motor cables with a low voltage current or by using space heaters.
Once the equipment is dry, repeat the insulation resistance test. The
minimum value for insulation resistance on a new installation at
startup or energizing is 1 MΩ. These readings can be recorded in
Table 11 on page 100
.
Commissioning Procedure
Next, check the field wiring (for example, motor cables and/or
incoming line cables).
ATT EN TI ON : Only skilled personnel with proper personal protective
equipment can commission a motor control center. Energizing a MCC for

EtherNet/IP Motor Control Centers
Basic information is provided in the following sections. For additional
information, see CENTERLINE® 2500 Motor Control Centers with
EtherNet/IP™ Network, publication 2500-TD003
.
Connection Count
The EtherNet/IP network can accommodate a vast number of nodes. The
EtherNet/IP network does not have a specific maximum number of nodes like
other fieldbus networks. The limit is based on the number of connections the
EtherNet/IP scanner can make.
To estimate the number of connections a network uses, visit
http://www.rockwellautomation.com/solutions/integrated architecture/
resources3.html for our EtherNet/IP Capacity Tool.
Cable Length Limitations
The EtherNet/IP network uses fiber or copper twisted-pair wiring. The
maximum length of copper twisted-pair wiring is 100 m between devices.
There is no cumulative length for the entire network. Fiber cable length
varies by cable design. Inside the MCC, all cables are copper twisted pair.
IMPORTANT The 100 m maximum length must account for Ethernet cable inside the
column. To help determine cable lengths for your application, each MCC
is shipped with documentation that identifies the cable length that is
used within the MCC. This cable length must be added to the length
between the GracePort® and the externally connected device.

Cable Routing
Each EtherNet/IP network has one or two Stratix 5700™ switches typically
mounted in the top horizontal wireway in the standard configuration. The
number of switches depends on the number of units in the column. Cables
connected to the switch are then routed to EtherNet/IP devices in the
column. Up to 24 EtherNet/IP ports can be provided in each
CENTERLINE 2500 column.
In a standard MCC column, the vertical network wireway has EtherNet/IP
connections equal to the number of units (up to 24) for that column. Devices
that require 24V DC to power up must have it supplied through pins B4 and
B5 in the control plug.
IMPORTANT Pins B4 and B5 in the control plug are reserved for 24V DC power; avoid
using for other reasons.
Connection to the EtherNet/IP network and the control plug is made when
a unit is in the Connected or Test position.

MCC Cable Types
ATT EN TI ON : Do not apply high voltage to any installed EtherNet/IP cable
system or its connectors.
The CENTERLINE 2500 MCCs use a high-voltage 600V Ethernet cable
designed to perform above TIA 568-B.2 and ODVA Ethernet standards.
These cables have the following features:
• Foil and braided shield, PVC, eight conductor (four pair)
• 600V PVC cable designed to support high-voltage applications
• On-Machine™ rated cable for use in a cable tray shared with highvoltage power cables
• RJ45 insulation displacement connector available for field

Ethernet Power Supply
IMPORTANT Many EtherNet/IP components require 24V DC power source to operate.
The power supply must be EtherNet/IP compatible as specified in the
ODVA requirements.
Power supplies that do not satisfy both preceding points can result in
damage to the EtherNet/IP signal and components, and failure to comply
with local codes and inspection.
A power supply unit that meets EtherNet/IP requirements can be supplied
with the MCC. A cable connects the output of the power supply to pins C3
and C4 of the control plug in the network wireway. This cable is already
connected when the power supply unit ships installed in the MCC.
Redundant configurations are also available.
Connect Power Supplies–Remote or in the MCC Lineup
Connect power supplies according to guidelines to minimize voltage drops in
the EtherNet/IP system while providing proper supply voltage to system
devices. For detailed connection instruction, see the Converged Plantwide
Ethernet Design and Implementation Guide, publication ENET-TD001
.
Network Power Supply and the Protective Earth Circuit
The EtherNet/IP network is grounded at the various components via the
component ground. Therefore, no further grounding is needed for the
Ethernet cables.
IMPORTANT Do not connect the 24V DC common in the power supply bucket to the PE.
Doing so violates the grounding guidelines for the various EtherNet/IP
components.
Connecting Two Power Supplies
Install an additional 24V DC Class 1 power supply for MCC lineups with 14
or more columns. When using two supplies, provide a break between the two
24V DC networks. Locate the appropriate break for the two networks and
verify that the terminal blocks are not connected between these two columns.

System Design Installation Checklist
When you install an EtherNet/IP MCC, verify the following before you
apply power to the network:
• Only one power supply is connected for every 14 sections of MCC.
• The power supply for the system is 24V DC.
• The PE is connected.
• Connections are inspected to detect and correct any loose wires,
opens, or shorts.

DeviceNet Power Supply
IMPORTANT The DeviceNet cable system requires a 24V DC power source to operate.
The power supply must be DeviceNet compatible as specified in the ODVA
requirements.
Power supplies that do not satisfy both points above can result in damage
to the DeviceNet signal and components, and failure to comply with local
codes and inspection.
rt
in
A power supply unit that meets DeviceNet requirements can be supplied
with the MCC. A cable connects the output of the power supply to a
DeviceNet port in the control and network wireway. This cable is already
connected when the power supply unit ships installed in the MCC.
Redundant configurations are also available.
Remote power supplies shall meet the following requirements, per ODVA:
• Rated 24V DC (±1%)
• Rise time of less than 250 milliseconds to within 5% of 24V DC at full
load of 8 A
• Current limit protection of 8 Amps continuous and 10 Amps for th
fi
rst 250 ms
• Sized correctly to provide each device with its required power—each
device typically requires 90…165
•

Connect Power Supplies–Remote or in the MCC Lineup
Connect power supplies according to these guidelines to minimize voltage
drops in the DeviceNet system and help achieve proper supply voltage to
system devices. For detailed connection instructions, see the Media Design
Installation Guide, publication DNET-UM072
.
Network Power Supply and the Protective Earth Circuit
The DeviceNet cable must be connected to the PE circuit at only one
location. The ideal choice is at the power supply. Connect the power supply
and 24V DC common (black wire) to the PE circuit by using #8 AWG wire.
Best PE Practice
• If the power supply comes installed in the MCC, the black 24V DC
common terminal is connected to the PE within the un

Connecting Two Power Supplies
An additional 24V DC Class 1 power supply must be installed for MCC
lineups with more than 14 columns. When using two supplies, the red
conductor between the power supplies must be broken. Locate a linking
connector between columns and disconnect the red conductor.
Connect only ONE of the two power supplies to the PE.

MCC Lineup With More Than 14 Columns
Break Red Conductor Power Supply
Position each power supply so it feeds a maximum of seven columns to the
left or right (see the following sample lineup).
MCC lineups with more than 14 columns could exceed the 75 m trunk
length limit to support 500 Kbps communications. When the trunk length
exceeds this limit, specify 250 Kbps communications.
Electronic Data Sheets (EDS)
This section applies to any MCC with IntelliCENTER software that is
inst
alled on a DeviceNet or EtherNet/IP network.
After IntelliCENTER software is installed, an Electronic Data Sheet (EDS)
must be registered for each unique device in the MCC. This section details
how to perform that task.
Overview
EDS files are simple text files that are used by network configuration tools—
such as RSNetWorx™, RSLogix 5000, or IntelliCENTER software—to help
identify products and easily commission them on a network. EDS files
describe device type, version, and configurable parameters on a DeviceNet or
EtherNet/IP network.
Where to Find EDS Files
The IntelliCENTER data CD has a directory
(<cdrom>:\<order>\<item>\EDS) that contains the EDS files necessary for
the devices in your IntelliCENTER MCC. The installation program
automatically registers the EDS files.
An ‘EDS file’ CD is provided with EDS files for all DeviceNet and
EtherNet/IP products that are found in MCCs.

Installing EDS Files
EDS files are installed with a program from Rockwell Software® called
‘RSHWare.exe’. This program is included on the IntelliCENTER data CD
and in the same directory as the EDS files.
Follow these steps to install EDS files for a DeviceNet or EtherNet/IP
network.
1. Ru n t he pr og r am ‘ RS H War e .e xe ’.

Uploading EDS Files from the Device
RSNetWorx for EtherNet/IP or RSNetWorx for DeviceNet software can be
used to upload an EDS file directly from a device. If an EDS file cannot be
found by other methods, see the RSNetWorx help file for steps to upload an
EDS file.
