Power Generation & Distribution
Monitor and control turbines, generators, and substations. 18-slot capacity accommodates extensive I/O for SCADA integration, with deterministic cycle times for protective relay coordination.
Pharmaceutical Manufacturing
Ensure batch traceability and FDA 21 CFR Part 11 compliance with high-availability S7-400H systems. Rack supports redundant CPUs and power supplies for continuous production.
Automotive Assembly
Coordinate multi-robot welding lines, paint booths, and final assembly stations. Scalable architecture allows expansion to 21 racks (378 slots) for plant-wide control.
Water & Wastewater Treatment
Manage pumping stations, filtration systems, and chemical dosing with distributed I/O across multiple racks. Interface modules enable remote rack placement up to 10 meters apart.
🛠️ Installation & Commissioning Guide
Pre-Installation Planning
- Cabinet Selection – Ensure cabinet depth ≥250mm to accommodate rack + cable routing
- Power Budget Calculation – Sum module power consumption, select PS 407 capacity accordingly
- Cooling Requirements – Provide 50mm clearance above/below rack for ventilation
- Grounding Strategy – Plan equipotential bonding for EMC compliance
Mechanical Installation
- Position Rack – Mount horizontally at ergonomic height (1200-1500mm from floor)
- Secure Mounting – Use M6 screws through pre-drilled holes in rack profile
- Verify Alignment – Use level tool to ensure rack is perfectly horizontal (critical for module seating)
- Install Grounding – Connect rack to cabinet ground via M6 grounding stud
Module Installation Sequence
- Power Supply First – Install PS 407 in slot 1 (and slot 2 if redundant)
- CPU Installation – Insert CPU in slot 3 (or slots 3-4 for H-system)
- I/O Modules – Install signal modules from left to right (slots 5-18)
- Front Connectors – Attach pre-wired front connectors to each module
- Locking Mechanisms – Engage module locks to prevent accidental removal
Electrical Commissioning
- Power-Up Sequence – Energize PS 407, verify green OK LED
- CPU Initialization – Check CPU RUN/STOP switch, download program via STEP 7
- I/O Diagnostics – Use STEP 7 Hardware Config to verify all modules detected
- Functional Testing – Test each I/O point individually before production release

❓ Frequently Asked Questions
Q: What's the difference between UR2-H and CR2 racks?
A: Both support H-systems, but UR2-H is a universal rack (can be central or expansion), while CR2 is specifically designed as a central rack with integrated interface module slots.
Q: Can I use this rack for S7-300 modules?
A: No, S7-400 racks are NOT compatible with S7-300 modules. Use 6ES7390-series racks for S7-300.
Q: How many power supplies do I need?
A: Minimum 1× PS 407 in slot 1. For redundancy (H-systems), install a second PS 407 in slot 2.
Q: What's the maximum distance between racks?
A: Up to 10 meters with IM 460-3 interface modules. For longer distances, use distributed I/O (Profibus DP/Profinet).
Q: Can I hot-swap modules during operation?
A: Yes, with redundant power supplies and proper STEP 7 configuration. Always follow Siemens hot-swap procedures to prevent data loss.
Q: Is vertical mounting supported?
A: Not recommended. Vertical mounting reduces operating temperature range to 0-40°C and may cause module seating issues.
