Replacement Note

Mitsubishi Electric’s FR-A700 replacement guide maps the base model FR-A740-15K to FR-A840-15K. Verify the full order code, option hardware, parameters and panel details before migration; the mapping does not by itself confirm a direct swap for every regional suffix.

Installation Guidelines

Mounting Position: Always install the drive vertically on a flat, non-flammable surface to facilitate optimal air convection.
Clearance Requirements: Ensure a minimum clearance of 50 mm on both sides and 100 mm above and below the unit for proper heat dissipation.
Grounding: Connect the protective earth terminal strictly to a low-impedance ground to prevent electromagnetic interference and electric shock.
Environmental Limits: Protect the unit from direct sunlight, corrosive gases, flammable materials, and fine conductive dust.

Compliance and Certifications

CE (European Conformity)
UL Listed / cUL
