131L9864 Danfoss VLT HVAC Basic Drive FC-101 2.2kW Frequency Converter

Product Overview

The 131L9864 (131L9864) is a high-efficiency VLT® HVAC Basic Drive FC-101 designed by Danfoss to provide precision motor control for 2.2 kW (3.0 HP) applications. Engineered specifically for the HVAC sector, this frequency converter optimizes the performance of pumps, fans, and compressors in commercial and industrial building automation systems. By utilizing advanced variable speed technology, the 131L9864 significantly reduces energy consumption and mechanical wear on drive components. Its compact IP20 enclosure is designed for efficient cabinet integration, while the integrated H4 RFI filter ensures electromagnetic compatibility (Class A1/C2), making it a reliable choice for mission-critical ventilation and climate control infrastructures.

Technical Specifications

Technical FAQs

Does the 131L9864 support communication with building management systems (BMS)?

Yes. The FC-101 series comes standard with built-in HVAC protocols including BACnet, Modbus RTU, and FC Protocol. This allows the 131L9864 to seamlessly integrate with central controllers for remote monitoring and automated energy management.

Is an external filter required to meet industrial EMC standards?

This unit includes an integrated H4 (Class A1/C2) RFI filter. For most industrial and commercial installations, no additional filtering is required to meet electromagnetic emission standards, provided that shielded motor cables are installed correctly.

What are the cooling requirements for this 2.2 kW drive?

The 131L9864 is air-cooled. For IP20 chassis models, ensure the control cabinet has sufficient airflow to keep the ambient temperature below 40 deg C for full-rated performance. Operation up to 50 deg C is possible with calculated current derating.

Engineering & Installation Guide

• Vertical Mounting & Airflow: To ensure proper convection through the heat sink, the drive must be mounted vertically. Maintain at least 100 mm of free space above and below the unit. The FC-101 supports side-by-side mounting ("bookstyle"), which allows for high-density installation in compact electrical panels.

• Cable Shielding Protocols: To utilize the benefits of the H4 RFI filter, use screened (shielded) motor cables. The shield must be connected to the metal decoupling plate of the drive using a 360-degree clamp to effectively divert high-frequency noise to ground and protect nearby sensitive electronics.

• Motor Protection Settings: Upon commissioning, ensure the motor nameplate data (Voltage, Frequency, Current) is accurately entered into the drive's parameter group 1-2. This allows the 131L9864 to provide thermal overload protection and optimize the VVC+ (Voltage Vector Control) for maximum torque efficiency.
