4. Installation & Application Notes
- Mount vertically/horizontally per line module manual; ensure airflow for cooling
- Match input voltage to line module mains (500–690V 3AC)
- Use shielded cables for fan output to reduce EMI
- Verify fan voltage/current rating matches transformer output
- Do not exceed rated input voltage/frequency; protect with appropriate fuses
- Technical data subject to change; always verify with latest Siemens documentation
