Installation precautions
● Removal procedure of the front cover is different. (Refer to page 2-7.)
● Plug-in options of the FR-A700 series are not compatible.
● Operation panel (FR-DU07) cannot be used.
Wiring precautions
The spring clamp type terminal block has changed to the screw type. Use of blade terminals is rec-
ommended.
Instructions for continuous use of the FR-PU07 (parameter unit)
● For the FR-A800 series, many functions (parameters) have been added. When setting these
parameters, the parameter names and setting ranges are not displayed.
● Only the parameter with the numbers up to "999" can be read and set. The parameters with the
numbers after "999" cannot be read or set.
● Many protective functions have been added for the FR-A800 series. These functions are available,
but all faults are displayed as "Fault". When the faults history is checked, "ERR" appears. Added
faults will not appear on the parameter unit. (However, MT1 to MT3 are displayed as MT.)
● Parameter copy/verification function are not available.
Copying parameter settings
The FR-A700 series' parameter settings can be easily copied to the FR-A800 series by using the setup
software (FR Configurator2). (Not supported by the setup software FR-SW3-SETUP or older.)

An optional converter unit (FR-CC2) is
required for separated converter types.
For the FR-A820-03800(75K) or higher, the
FRA840-02160(75K) or higher, and when a
75 kW or higher motor is used, select a DC
reactor suitable for the applicable motor
capacity. (A DC reactor is not included.)
Separated converter types (converter unit
FR-CC2) and IP55 compatible models have
a built-in DC reactor.
