SecureConnect™ Overview
• Personnel safety feature that allows operators to disconnect power from a MCC plug-in unit without opening the enclosure door or being in the arc flash boundary1
Provide a safer work environment with SecureConnect
• Address the growing concern of working inside the arc flash boundary on live equipment
• Proactively address known hazards identified by major safety organizations and standards
– NEC 2011– IEEE 1584 & C37.20.7– NFPA70E 2012
1 Use of safety features varies depending on MCC design

SecureConnect Benefits
Reduce Electrical Shock and Exposure to Harmful Voltages•Connect and Disconnect unit stabs without having to be exposed to live electrical parts
– Remote operator allows you to work outside the arc-flash boundary of the MCC
• Further mitigate safety risk using our patented multi-point validation system – Provides redundant indication for
disconnect position
• Enhanced compliance with NFPA70E Section 110.3 for your Electrical Safety Program

SecureConnect Benefits
Higher Availability•Electrically isolates the equipment that needs servicing without impact to other operating equipment•Helps eliminate unintended downtime caused by troubleshooting electrical faults•Reduces the need for live electrical work permits and maintenance by removing voltage from line side of unit
Minimal impact to current or future electrical design•No impact to Space Factor of units •Apply to select units or all units in MCC line-up•No special tools required; a simple ¼” hex driver and socket wrench required
Improve safety functionality with no impact on unit size

Key Safety FeaturesStab Housing Shutters
• Two sets of shutters for increased electrical isolation– Bus cover and stab housing shutters
• Shutters are only opened when a connection to the Vertical Power Bus is needed
– Provides additional protection of power stabs when unit is removed from structure
• Limit switch provides feedback to indicate the shutters are closed

Key Safety FeaturesPower Stab Withdrawal
Simple use of continuity to verify electrical power has been completely removed from unit
Series circuit using power stabs in
withdrawn position

Mechanical Lock-outs
• When the Disconnect Operator is in the “Off” position, a mechanical lock-out can be applied to prevent the stabs from being placed in the Connected position
• Any standard lock-out tag-out device can be used to secure the lock-out mechanism
• If a lock-out tag-out device is placed on the lock-out mechanism, the door can be opened
• Versatile interlock mechanism designed to make servicing safer

Mechanical Interlocks
Three mechanical interlocks are provided to help ensure safe operation of your SecureConnect units:
Tamper Resistant Interlocks
Stab Withdrawal Interlock – prevents unit from having the stabs Disconnected from the vertical bus while the Disconnect Operator is in the ‘On’ position.
Tool Insertion Interlock – prevents accessibility to the SecureConnect access port while the Disconnect Operator is in the “On” position.
Defeatable Interlock
Unit Insertion & Removal Interlock – prevents unit from being inserted or withdrawn while the stabs are in the “Connected” position.

Remote Operator Option
• Allows you to work outside the arc-flash boundary of the MCC while Connecting and Disconnecting unit stabs
– Provides indication for safe entry back inside Arc Flash boundary– 24 VDC Motor – Allows for operation
up to 30 feet away
Attach the remote operator mechanism to the front of the
SecureConnect unit Release Mechanism

Retrofit Capabilities
Protect your investment and continue to support our industry leading design and install base
• Retrofit kits will be available through the Customer Support & Maintenance field service engineers:
– Modification of existing bus covers to new Series P of CENTERLINE 2100 MCC
o Allows you to use existing units along with new SecureConnect units without any other modification
– Labor to remove existing units, support pans, and ground bus, and any additional hardware to modify existing bus covers
• Retrofit kits do NOT include new SecureConnect units– Units must be purchased as a separate item
• Contact your local Rockwell Automation Sales Engineer or Distributor for more information
