🛠️ Installation & Commissioning

Pre-Installation Checklist

✓ Verify cabinet dimensions (minimum 600mm width recommended)
✓ Ensure adequate ventilation (50mm clearance above/below rack)
✓ Confirm power supply capacity (calculate total module consumption)
✓ Prepare grounding infrastructure (PE connection required)

Step-by-Step Installation

Mounting the Rack
- Position rack horizontally in cabinet at desired height
- Use pre-drilled mounting holes (M6 screws recommended)
- Verify rack is level using spirit level (critical for module seating)
- Secure rack firmly to prevent vibration-induced loosening
Grounding Connection
- Connect rack grounding terminal to cabinet PE rail
- Use minimum 6mm² copper wire for grounding
- Ensure low-impedance ground path (<0.1Ω resistance)
Module Installation Sequence
- Install power supply in Slot 1 (do not power on yet)
- Install CPU in Slot 2
- Install I/O and communication modules in Slots 3-9 (left to right)
- Verify all modules are fully seated (locking mechanisms engaged)
Power-Up Procedure
- Connect 24V DC to power supply input terminals
- Verify power supply LED indicators (green = OK)
- Check CPU status LEDs (SF, BF, RUN/STOP)
- Use STEP 7 to download configuration and verify rack topology

💡 Installation Best Practices

Leave 100mm clearance on left/right sides for cable routing
Use cable ducts to organize field wiring and prevent clutter
Label all modules with slot numbers and functional descriptions
Document rack configuration in STEP 7 project for future reference

❓ Frequently Asked Questions

Q: What's the difference between UR1 and UR2 racks?
A: UR1 has 9 slots (compact systems), UR2 has 18 slots (large systems). Both are central racks.

Q: Can I use S7-300 modules in an S7-400 rack?
A: No, S7-300 and S7-400 modules are not interchangeable due to different backplane architectures.

Q: How many expansion racks can I connect?
A: Up to 21 expansion racks (ER1/ER2) using IM 460 interface modules, for a maximum of 198 slots.

Q: Does this rack support redundant CPUs?
A: Yes, UR1 supports H-system redundancy with two CPUs in Slots 2 and 3 (requires redundant power supplies).

Q: Can I mount the rack vertically?
A: Yes, but operating temperature is derated to 0-40°C (vs. 0-60°C horizontal). Ensure adequate ventilation.

Q: Is this rack compatible with S7-1500 modules?
A: No, S7-1500 uses a completely different rack system (rail-mounted). Not compatible with S7-400 racks.
