Installation Guidelines

1. De-energize System: Before installation, ensure all power to the SIMATIC S5 rack and associated equipment is completely disconnected and locked out to prevent electrical hazards.
2. Mounting: Securely mount the power supply unit within the designated slot or area in the SIMATIC S5 rack or enclosure. Ensure proper ventilation space around the unit.
3. Input Power Connection: Connect the appropriate AC input voltage (120 V AC or 230 V AC) to the designated terminals. Verify correct polarity and secure all connections.
4. Output Power Connection: Connect the 5 V DC output to the SIMATIC S5 backplane or modules as per the system wiring diagram. Ensure proper connection to the 5 V and ground terminals.
5. Grounding: Ensure the power supply unit and the SIMATIC S5 system are properly grounded to a common earth ground to minimize electrical noise and ensure safety.
6. Cable Routing: Route power cables away from signal and communication cables to prevent interference. Use appropriate cable management techniques.
7. Verification: After installation, double-check all connections for security and correctness before re-energizing the system.
