Selection Suggestions and Precautions
Selection Suggestions:
- Choose PM862K02 when hardware redundancy is required.
- Confirm system version compatibility (800xA 6.0.2 or later).
- Verify available application memory and I/O capacity for the project.
- Consider higher-performance controllers (PM866A / PM891) for larger or more demanding applications.
- Ensure matching baseplates, cables, and batteries are included or available.
Precautions:
- No software license is included — licenses must be ordered separately.
- Proper installation of RCU-Link and CEX-bus cables is critical for redundancy.
- Follow ABB guidelines for power supply (preferably redundant 24 V DC).
- Use only approved CompactFlash cards and batteries.
- Configuration and firmware updates must be performed with official ABB tools.
- Handle with ESD precautions and observe correct mounting orientation.
