Page 11: Fire Prevention
Electric shock prevention WARNING  Do not remove the front cover or the wiring cover while the inverter power is ON, and do not run the inverter with the front cover or the wiring cover removed as the exposed high voltage terminals or the charging part of the circuitry can be touched.
Page 12 Injury prevention CAUTION  The voltage applied to each terminal must be as specified in the Instruction Manual. Otherwise burst, damage, etc. may occur.  The cables must be connected to the correct terminals. Otherwise burst, damage, etc. may occur. ...
Page 13 CAUTION Transportation and installing  Any person who is opening a package using a sharp object, such as a knife or cutter, must wear gloves to prevent injuries caused by the edge of the sharp object.  The product must be transported in correct method that corresponds to the weight. Failure to do so may lead to injuries. ...
Page 14 WARNING Usage  Any person must stay away from the inverter after using the retry function as the inverter will restart suddenly after inverter output shutoff.  It may happen depending on the inverter's function settings that the inverter does not stop its output even when the STOP/RESET key on the operation panel is pressed.
Page 15 CAUTION Usage  The electronic thermal O/L relay function may not be enough for protection of a motor from overheating. It is recommended to install an external thermal relay or a PTC thermistor for overheat protection.  Do not use a magnetic contactor on the inverter input side for frequent starting/stopping of the inverter. Otherwise the life of the inverter decreases.

Page 38: Installation Of The Inverter And Enclosure Design
Installation of the inverter and enclosure design When designing or manufacturing an inverter enclosure, determine the structure, size, and device layout of the enclosure by fully considering the conditions such as heat generation of the contained devices and the operating environment. An inverter unit uses many semiconductor devices.
Page 39 NOTE • For the amount of heat generated by the inverter unit, refer to page  Humidity Operate the inverter within the ambient air humidity of usually 45 to 90% (up to 95% with circuit board coating). Too high humidity will pose problems of reduced insulation and metal corrosion. On the other hand, too low humidity may cause a spatial electrical breakdown.
Page 40  Vibration, impact The vibration resistance of the inverter is up to 5.9 m/s (2.9 m/s or less for the FR-A840-04320(160K) or higher) at 10 to 55 Hz frequency and 1 mm amplitude for the directions of X, Y, Z axes. Applying vibration and impacts for a long time may loosen the structures and cause poor contacts of connectors, even if those vibration and impacts are within the specified values.
Page 41: Amount Of Heat Generated By The Inverter
2.3.2 Amount of heat generated by the inverter  Installing the heatsink inside the enclosure When the heatsink is installed inside the enclosure, the amount of heat generated by the inverter unit is shown in the following tables. Amount of heat generated (W) Voltage Inverter model FR-A820-00046(0.4K)

 Arrangement of the ventilation fan and inverter Heat generated in the inverter is blown up from the bottom of the unit as warm air by the cooling fan. When installing a ventilation fan for that heat, determine the place of ventilation fan installation after fully considering an air flow. (Air passes through areas of low resistance.
Page 46  Mount point change of installation frame from the rear to the front The upper and lower installation frames are attached on the inverter (one for each position). Change the mount point of the upper and lower installation frames from the rear to the front as shown in the figure. When reattaching the installation frames, make sure that the installation orientation is correct.

Note that motor noise increases. Selecting Pr.240 Soft-PWM operation selection makes the sound inoffensive. To ensure that the motor is protected against line-to-line leakage currents, it is recommended to use a temperature sensor to directly detect motor temperature.

Page 126: Installation Of A Reactor
Installation of a reactor When the inverter is connected near a large-capacity power transformer (1000 kVA or more) or when a power factor correction capacitor is to be switched over, an excessive peak current may flow in the power input circuit, damaging the converter circuit. To prevent this, always install an AC reactor (FR-HAL), which is available as an option.
Page 127: Power Shutdown And Magnetic Contactor (Mc)
Power shutdown and magnetic contactor (MC)  Inverter input side magnetic contactor (MC) On the inverter input side, it is recommended to provide an MC for the following purposes. (Refer to page 29 for selection.) • To disconnect the inverter from the power supply at activation of a protective function or at malfunctioning of the driving system (emergency stop, etc.).
Page 128  Handling of the manual contactor on the inverter's output side A PM motor is a synchronous motor with high-performance magnets embedded inside. High-voltage is generated at the motor terminals while the motor is running even after the inverter power is turned OFF. In an application where the PM motor is driven by the load even after the inverter is powered OFF, a low-voltage manual contactor must be connected at the inverter's output side.

Page 132 Refer to Check by Checkpoint Countermeasure page user When a motor is driven by the inverter, axial voltage is generated on the motor shaft, which may cause electrical corrosion of the bearing in rare cases depending on the wiring, load, operating conditions of the motor or specific inverter settings (high carrier frequency and EMC filter ON).
Page 133: Failsafe System Which Uses The Inverter
Failsafe system which uses the inverter When a fault is detected by the protective function, the protective function activates and outputs the Fault signal. However, the Fault signal may not be output at an inverter's fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi assures the best quality products, provide an interlock which uses inverter status output signals to prevent accidents such as damage to the machine when the inverter fails for some reason.
Page 134  Checking the inverter operating status by the start signal input to the inverter and by the Inverter running signal output from the inverter ... (c) The Inverter running (RUN) signal is output when the inverter is running. (The RUN signal is assigned to terminal RUN in the initial setting.) Check if the RUN signal is output while a start signal (the STF/STR signal for forward/reverse rotation command) is input to the inverter.
Page 135  Command speed and actual operation check Check for a gap between the actual speed and commanded speed by comparing the inverter's speed command and the speed detected by the speed detector.
