The ATV21WU40N4 is a high-performance Variable Frequency Drive (VFD) from Schneider Electric’s Altivar 21 series. Engineered to provide precise control for 4 kW (5 HP) motor applications, this drive is particularly well-suited for HVAC systems, pumps, and fans where energy efficiency and operational precision are critical. With a 480V input, an integrated EMC filter (Class A), and a robust IP54-rated enclosure, the ATV21WU40N4 is designed to operate reliably in challenging industrial environments.

Description

The Altivar 21 series offers advanced speed control, allowing users to optimize motor performance and reduce power consumption significantly. The IP54 rating ensures the unit is protected against dust and water splashes, making it suitable for direct machine or wall-mounting in industrial settings without requiring a sealed cabinet. While this specific model is now in the Phase-Out product lifecycle, it remains a highly capable solution for existing installations or legacy machine upgrades.

Installation Guidelines

Mounting: Ensure the VFD is mounted vertically on a flat surface to facilitate passive cooling. Adhere to the recommended clearance distances around the unit to prevent thermal buildup.
Environmental Safety: The IP54 rating provides protection against moisture and dust; however, avoid installation in direct sunlight or areas subject to extreme chemical vapors.
Wiring: Connect the 3-phase 480V input to the primary terminal block and the motor leads to the output terminals. Always verify that the motor's nominal voltage and current ratings are compatible with the drive settings.
Grounding: To ensure compliance with EMC standards and safe operation, verify that the drive chassis is connected to a high-integrity, low-impedance earth ground.

What does the IP54 rating signify for the ATV21WU40N4?

The IP54 rating indicates that the unit is protected against dust ingress (to a level where operation is not impaired) and is protected against splashing water from any direction, making it suitable for many industrial settings without a sealed enclosure.

What is the primary function of the integrated Class A EMC filter?

The Class A EMC filter is designed to suppress electromagnetic noise generated by the drive, ensuring that surrounding electronic equipment is not disrupted by interference.

Since this unit is in a 'Phase-Out' stage, what should I consider?

Being in a 'Phase-Out' phase means that while the product is highly reliable, it may be subject to limited availability or support in the future. It is advisable to consult with Schneider Electric regarding migration paths to newer drive series for long-term project planning.
