Main circuit terminals Cable gauge of main circuit terminals and earth (ground) terminals Use an appropriate cable gauge to suppress the voltage drop to 2% or less. If the wiring distance is long between the inverter and motor, the voltage drop in the main circuit will cause the motor torque to decrease especially at a low speed. The following table indicates a selection example for the wiring length of 20 m.

When a fault is detected by the protective function, the protective function activates and output a Fault (ALM) signal. However, a fault signal may not be output at an inverter's fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi Electric 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.
PRECAUTIONS FOR USE OF THE INVERTER The FR-B, B3 series inverter is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the product. Before starting operation, always recheck the following points. •...
