Chapter 1
System Overview
CENTERLINE 2500 Motor Control Centers (MCCs) are designed for applications
that must comply with international standards and practices for low voltage motor
control centers. The CENTERLINE 2500 MCC is ideal for tough, demanding
industrial applications where uptime and ease of maintenance is required.
The time-proven CENTERLINE power bus structure distributes line power
throughout the MCC via an isolated bus work structure. Standard, center-fed,
300 A rated vertical bus supplies power to the individual units above and below the
horizontal bus for an effective 600 A capacity and virtually unrestricted unit
arrangement. An optional 600 A vertical bus provides an effective rating of 1200 A.
ArcShield Rating
The CENTERLINE MCC is also available with an ArcShield™ rating. The
ArcShield rating includes arc-resistant features for enhanced protection in the
event of internal arcing faults.
In addition to 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
• Protection up 300 ms at 480V/65 kA

System Overview Chapter 1
IntelliCENTER Software
IntelliCENTER MCCs can be provided with pre-configured IntelliCENTER
software. The software is capable of viewing, managing, and configuring multiple
MCC line-ups. The IntelliCENTER software communication driver lets the
software be installed and operated on EtherNet/IP or DeviceNet. The
IntelliCENTER software can function as a stand alone 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additional mechanical interlock helps prevent the unit from being withdrawn or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.

Identifies Column
Sequence Numbering
Motor Control Center Sequence Numbering
CENTERLINE 2500 MCCs are designed so functionality is not affected by the
column numbering sequence. However, we recommend that columns be
installed in sequential order.
Each CENTERLINE 2500 MCC column nameplate identifies column sequence
numbering, for example, MCC column 1 of 1 or 1 of 5.
Figure 8 - Column Nameplates
Columns are numbered to match factory-supplied MCC elevation drawings.
Numbering each column helps installers and users 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.
Leftmost column must be installed in the proper location for the bus to splice.
(Both ends of double-front MCCs must be installed as ends for splicing.)
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.

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 watertight. Equipment that extends from the
structures is also protected.
Heavy duty/export packaging is similar to standard packaging, but uses a poly
wrap suitable for occasional water-spray. In addition, wood framing and sheeting
surround the columns. Heavy duty/export packaging is not watertight,
waterproof, or intended for long-term storage.
Upon delivery of the MCC, refer to the packing slip shipped with your MCC for
sizes and exact shipping weights, as well as the shipment for lost or damaged
items. If lost or damaged items are detected, refer to the steps described in

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 Motor Control
Centers, publication 2100-IN040
CENTERLINE 2500 MCCs, units and related equipment must be stored in a
clean, dry environment with ambient temperatures ranging from -25…55 °C
(-13…131 °F). For short periods, not exceeding 24 hours, temperatures of up to
70 °C (158 °F) are allowed. Take care to help prevent damage from exposure to
excessive humidity, vibration, and shock.

Location Planning
When planning the location for your CENTERLINE 2500 MCC, consider:
• Cable entry and exit points
• Busways
• Overall height of installation area
• Alignment with other equipment
• Future needs
• Environment
The area must be level and the environment must be compatible with the degree
of protection provided by the enclosure.
ArcShield Clearance Space
You need a minimum 300 mm of clearance space above the MCC. This space is
needed to vent the pressure relief plates in case of an arc flash.
