注意事项 PRECAUTIONS

1 Remote sense wiring: Route RS+ and RS- as a twisted pair; do not short or reverse them to prevent permanent damage

2 Cooling requirements: Ensure adequate cooling (natural convection or 25 CFM airflow) to maintain rated power output

3 Derating guidelines: Refer to temperature and input voltage derating curves for non-standard operating conditions

4 Safety installation: Follow class I grounding requirements; ensure proper isolation as per specified voltage limits

5 Connector compatibility: Use recommended mating connectors (per pin-out diagrams) for all ports to ensure secure connections

6 Critical application restriction: Not authorized for use in life support systems or critical components where failure could cause harm

7 Mechanical installation: Adhere to specified dimensions, screw specs, and torque limits for secure mounting

8 Guarantee and changes: CUI offers a 2-year limited warranty; product specifications may change without prior notice
