Description

Engineered for heavy-duty fan and pump speed control, the Mitsubishi Electric FR-F840-00380-2-60 is an industrial variable frequency drive (VFD) from the premium FR-F800 Series. Operating within the 400V three-phase class, this inverter delivers a Light Duty (LD) capacity of 18.5 kW. This specific unit features the robust -60 specification, signifying that internal circuit boards are treated with a specialized protective conformal coating and include plated conductors. This added layer of defense prevents degradation in corrosive, humid, or dusty environments, ensuring maximum operational uptime in wastewater treatment facilities, commercial HVAC units, and industrial plant automation panels.

Key Features

Environmental Optimization (-60 Spec): Coated circuit boards and plated conductors resist airborne particulate contamination and corrosive gases.
Energy-Saving Excitation Control: Constantly calculates optimal magnetic flux to maximize motor efficiency and reduce active power consumption.
Dual-Rating Load Capacity: Supports both Light Duty (LD) and Super Light Duty (SLD) parameter settings for optimal matching to variable torque loads.
Integrated Safety Architecture: Complies with functional safety regulations for emergency shutdown capability without external contactors.

Applications

Industrial exhaust fans, ventilation hoods, and commercial HVAC blowers.
Centrifugal booster pumps and municipal water supply systems.
Cooling tower fans and air compressor control systems.

Empirical Engineering Insights

Alternative Models & Compatibility

When migrating legacy systems from the older FR-F740 series, parameter mappings can be transferred using FR Configurator2 software. However, please note that physical dimensions and wiring terminal layouts differ slightly. Ensure that panel backplate drill patterns are verified before mechanical mounting.

Application Pitfalls & Engineering Notes

The FR-F840-00380-2-60 is rated primarily for Light Duty (LD) application profiles (variable torque loads). If applying this drive to constant torque loads, such as heavy positive displacement pumps or conveyor drives, you must derate the continuous current output or transition to the FR-A840 series to prevent overcurrent trip events (E.OC1 to E.OC3) during startup acceleration.

Commissioning & Wiring Tips

Ensure that the built-in EMC filter is configured correctly for your local earthing system. When installing this unit on an IT (ungrounded) network or an asymmetric earthed system, disconnect the internal EMC filter grounding jumper to prevent high-frequency leakage currents from tripping upstream ground fault protective devices.

Installation Guidelines

CRITICAL WARNING: Hazardous voltages remain present on the internal DC bus capacitors even after the mains power is disconnected. De-energize all primary input lines and wait a minimum of 10 minutes. Use a reliable digital multimeter to measure and verify zero voltage across terminals P/+ and N/- before accessing the wiring terminals or executing service actions.

1

Mount the inverter vertically on a flat, non-flammable surface to maintain optimal heat sink thermal dissipation. Keep a minimum clearance of 50mm on both sides and 100mm above/below the unit.

2

Connect a dedicated high-integrity system ground to the earth terminals. Avoid daisy-chaining ground wiring between adjacent variable frequency drives to suppress common-mode high-frequency noise.

3

Ensure all power and control signal cables are strictly segregated. Use separate metal conduit runs for power lines and shielded control cables to prevent inductive electromagnetic coupling.

FAQ

What is the benefit of the -60 suffix on the FR-F840-00380-2-60?

The -60 suffix indicates that the internal printed circuit boards are treated with a protective conformal coating and have plated conductors, safeguarding the electronics against moisture, dust, and corrosive gas environments.

Can this drive be used with constant torque applications like cranes or heavy conveyors?

No, this model is designed with a Light Duty (LD) rating optimized for variable torque applications such as fans and centrifugal pumps. Constant torque loads require high starting torque and should be paired with the FR-A800 series.

How long must I wait to access the internal terminals after cutting the power?

You must wait at least 10 minutes to allow the DC bus capacitors to discharge fully, and then verify that there is zero voltage across terminals P/+ and N/- using a multimeter.

Does this drive include a built-in EMC filter?

Yes, it contains an integrated EMC filter. If you are operating the drive on an IT or asymmetric earthed grid, the filter ground connector should be disconnected to avoid leakage current trips.
