Important Technical Notes

1. Series Verification:​ The order number 027H0181 must be cross-referenced with the supplier to confirm the exact Danfoss VLT® series (e.g., FC-51, FC-101, FC-102, FC-111, FC-202). Dimensional drawings and minor specifications vary by series.

2. Input Power:​ Confirm the supply is single-phase 200-240V AC. Do not connect to three-phase or voltage outside this range.

3. Motor Compatibility:​ Designed for standard three-phase AC induction motors. Ensure motor nameplate data (Voltage, Current, Power) matches or is below the drive's rated output.

4. Enclosure Requirement:​ This is a chassis unit. It must be installed in a suitable enclosure (IP20/UL Type 1 or higher) to provide safety and environmental protection.

5. Thermal Management:​ Ensure adequate space for ventilation as per installation guidelines. Derating is required for ambient temperatures above 40°C.

6. EMC Compliance:​ For compliance with EMC directives, proper installation practices are required, including the use of RFI filters (often built-in or optional) and correct motor cable routing (shielded cables recommended).

7. Motor Protection:​ The drive provides electronic motor overload protection. Additional external short-circuit protection (fuses or circuit breakers) is required as per national wiring regulations.

8. Parameter Setup:​ Correct motor data must be entered into the drive, and auto-tuning is recommended for optimal performance with Sensorless Vector Control.
