Mitsubishi Electric FR-A840-03250-2-60 FR-A800 Inverter

Description

Engineered for high-demand industrial motor control, the FR-A840-03250-2-60 is a high-performance variable frequency drive (VFD) from the premium FR-A800 series by Mitsubishi Electric. This standard three-phase model is designed to optimize energy efficiency and deliver precise speed and torque control for heavy-duty applications. Featuring advanced vector control technology, the unit provides reliable operation across varying load profiles.

The FR-A840-03250-2-60 operates within the 400V class and is equipped with a Super Light Duty (SLD) rating designated by the 03250 code. This specific configuration includes the -2 CA terminal type and a protective -60 suffix package, which ensures the unit has a conformal circuit board coating (3C2 classification) for enhanced environmental resistance, without standard plated conductors. It represents a robust, industrial-grade solution for complex automation systems requiring reliable torque performance and network integration.

Installation Guidelines

To ensure safe and optimal operation of the FR-A840-03250-2-60 inverter, adhere to the following industrial installation protocols:

• Mounting Orientation: Mount the inverter vertically on a flat, non-combustible surface to promote proper natural convection cooling.
• Clearances: Maintain the recommended physical clearance around the drive's heat sinks and ventilation ports to prevent thermal accumulation.
• Wiring & Shielding: Utilize shielded cables for all control and signal wiring to mitigate electromagnetic interference (EMI). Ensure separate routing of power lines and control cables.
• Grounding: Connect the ground terminal securely to a dedicated system earth point in compliance with local electrical safety regulations.
• Environmental Limits: Install inside an IP-rated enclosure if operating in environments with high levels of dust, chemical vapors, or ambient temperatures exceeding specified operating thresholds.
