The FR-F 746 frequency inverter drives from Mitsubishi Electric complement the
standard units of the FR-F 740 series, adding a dust and splash proofed version
with an IP54 protection rating. The FR-F 746 series is designed for the special
needs of building services automation in the heating, ventilation and air conditioning
sector. The dust and splash proof version with an IP54 rating is very robust,
making it possible to install and operate the units in heavy-duty environments.
