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.

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 783: Measurement Of Main Circuit Voltages, Currents, And Powers
Measurement of main circuit voltages, currents, and powers Since the voltages and currents on the inverter power supply and output sides include harmonics, measurement data depends on the instruments used and circuits measured.

Page 785: Measurement Of Powers
A digital power meter (designed for inverter) can also be used to measure. 7.2.1 Measurement of powers Use digital power meters (for inverter) both on the inverter's input and output sides. Alternatively, use electrodynamic type single-phase wattmeters both on the inverter's input and output sides in the two-wattmeter or three-wattmeter method. As the current is liable to be imbalanced especially on the input side, it is recommended to use the three-wattmeter method.
Page 786: Use Of Ct And Transducer
Since the inverter input current tends to be unbalanced, measurement of three phases is recommended. The correct value cannot be obtained by measuring only one or two phases. On the other hand, the unbalanced ratio of each phase of the output current should be within 10%.
Page 787: Insulation Resistance Test Using Megger
In the initial setting of the CA type inverter, a pulse train proportional to the output frequency is output across the analog current output terminals CA and 5 on the inverter. Measure the current using an ammeter or tester. For detailed specifications of the analog current output terminal CA, refer to page 442.
