📊 Power Supply Sizing Guide
| PS Model | Output Current | Max Modules | Typical Use Case |
|---|---|---|---|
| PS 405 5A | 5A | Up to 8 modules | Small systems, UR1 racks |
| PS 405 10A | 10A | Up to 12 modules | Medium systems |
| PS 407 10A | 10A | Up to 12 modules | Standard UR2 configurations |
| PS 407 20A (This Product) | 20A | Up to 18 modules | Large systems, full UR2/CR2 racks |
How to Calculate Power Requirements
- List all modules in your rack (CPU, I/O, CP, FM)
- Find current consumption in each module's datasheet (typically 0.5-2A per module)
- Sum total current draw
- Add 20% safety margin
- Select PS with capacity ≥ total current + margin
Example: CPU 416 (1.5A) + 10× SM 421 (0.5A each) + 2× CP 443 (1A each) = 1.5 + 5 + 2 = 8.5A × 1.2 = 10.2A → Choose PS 407 20A for future expansion
🛠️ Installation Guide
Mounting Position
The PS 407 must be installed in Slot 1 (leftmost position) of the S7-400 rack. This is a fixed requirement per Siemens design.
Step-by-Step Installation
-
Pre-Installation
- Verify input voltage matches your facility (120V or 230V AC)
- Ensure rack is properly grounded
- Calculate total module current draw (see sizing guide above)
-
Physical Installation
- Slide PS 407 into Slot 1 from the front
- Push firmly until module seats on backplane connectors
- Engage top and bottom locking screws
-
Wiring
- Connect L (Line), N (Neutral), PE (Ground) to input terminals
- Use minimum 14 AWG wire for 20A capacity
- Tighten terminals to 0.5-0.6 Nm torque
- Verify PE connection has <0.1Ω resistance to cabinet ground
-
Power-Up
- Switch on AC input power
- Verify green ON LED illuminates
- Check DC OK LED (green = normal output)
- Monitor FAULT LED (off = no errors)
💡 Best Practices
- Use circuit breaker rated for 20A input current
- Install surge protection on AC input for harsh environments
- Leave 50mm clearance above PS for ventilation
- For redundancy, install second PS 407 in parallel (requires CR2 rack)

❓ FAQ
Q: Can I use this PS with S7-300 systems?
A: No, PS 407 is exclusively for S7-400. S7-300 uses PS 307 series power supplies.
Q: What's the difference between PS 405 and PS 407?
A: PS 407 has higher efficiency, better hold-up time, and supports redundant operation. PS 405 is more cost-effective for smaller systems.
Q: Can I run two PS 407 in parallel?
A: Yes, in CR2 segmented racks for N+1 redundancy. Each PS powers one segment independently.
Q: Does this PS work with 110V AC input?
A: Yes, it auto-senses 120-230V AC. No manual switching required.
Q: How do I know if I need 10A or 20A?
A: Calculate total module current draw + 20% margin. If >10A, choose 20A model for safety.
