SPECIFICATIONS
8.1.3 FR-A842 (400V class)
*1
The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi 4-pole standard motor.
*2
The rated output capacity indicated assumes that the output voltage is 440V.
*3
The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated duty, allow time
for the inverter and motor to return to or below the temperatures under 100% load.
*4
The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range. However,
the maximum point of the voltage waveform at the inverter output side is the power supply voltage multiplied by about √2
.
*5
Value for the ND rating
*6
FR-DU08: IP40 (except for the PU connector section)
*7
For the power voltage exceeding 480V, set Pr. 977 "Input voltage mode selection". (For details, refer to the FR-A800 Instruction Manual.)
For ratings of the converter unit (FR-CC2) refer to the FR-CC2 Instruction Manual.
8.1.4 FR-A846 (400V class)
*1
The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi 4-pole standard motor.
*2
The rated output capacity indicated assumes that the output voltage is 440V.
*3
The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated duty, allow time
for the inverter and motor to return to or below the temperatures under 100% load.
*4
The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range. However,
the maximum point of the voltage waveform at the inverter output side is the power supply voltage multiplied by about √2
.
*5
Value for the ND rating
*6
The rated input current indicates a value at a rated output voltage. The impedance at the power supply side (including those of the input reactor and
cables) affects the rated input current.
*7
The power supply capacity is the value when at the rated output current. It varies by the impedance at the power supply side (including those of the input
reactor and cables).
*8
For the power voltage exceeding 480V, set Pr. 977 "Input voltage mode selection". (For details, refer to the Instruction Manual.)
*9
UL Type 12 Enclosure-Suitable for Installation in a Compartment Handling Conditioned Air (Plenum)
*10
For compliance with IP55, remove the protective bushes and install the recommended cable glands.
