CC-SCMB02 operates with one or two compatible C300 controllers, 51199932-100 RAM charger, 51202340-100 mount, documented controller and power cables.
Engineered applications include C300 power-loss recovery, Redundant controller memory retention, Controller-cabinet resilience upgrade, Memory-backup assembly renewal.
Important Notice: De-energize the cabinet, identify both controller cables and the charger power lead, observe the mounting torque and verify backup status and retention diagnostics.
The first document organizes model-specific identity, technical data and system context. The second provides a separate installation, connection, commissioning and acceptance workflow.
Preserves volatile controller state through a cabinet power interruption.
Supports both controllers in a documented redundant arrangement.
Adds approved backup hardware to a C300 cabinet.
Restores memory retention while retaining charger and cable identities.
Verify the complete CC-SCMB02 marking and its assigned C300 memory-backup position before work.
Place the connected process and control strategy in the approved maintenance state.
Isolate the applicable cabinet supply and backup-power field energy before disconnecting conductors.
Record terminal numbers, channel assignments, polarity, shields and configured ranges before removal.
Use ESD controls and protect the backplane connector, terminal hardware and coated electronics.
Confirm the installed C300 controller and 51199932-100 charger and carrier arrangement against the approved project.
Restore power in a controlled sequence and clear only diagnostics created by the maintenance activity.
Complete charger status, controller connection and retention diagnostics and retain the measured result before returning the channel to automatic service.
