Page 16 Wiring (1) Cable size and other specifications of the main circuit terminals and the earthing terminal Select the recommended cable size to ensure that a voltage drop will be 2% at maximum. If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to decrease especially at the output of a low frequency.
Page 17 Wiring The line voltage drop can be calculated by the following formula: 3 × wire resistance [mΩ/m] × wiring distance [m] × current [A] Line voltage drop [V]= 1000 Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque reduction) in the low speed range.

Page 22 PRECAUTIONS FOR USE OF THE INVERTER (11) Do not use the inverter input side magnetic contactor to start/stop the inverter. Since repeated inrush currents at power ON will shorten the life of the converter circuit (switching life is about 1,000,000 times), frequent starts and stops of the MC must be avoided.
