Page 7: Safety Precautions
Indications and Meanings of Safety Information In this user's manual, the following precautions and signal words are used to provide information to ensure the safe use of the 3G3JX Inverter. The information provided here is vital to safety. Strictly observe the precautions provided.
Page 8 Safety Precautions CAUTION Do not connect resistors to the terminals (+1, P/+2, N/-) directly. Doing so might result in a small-scale fire, heat generation or damage to the unit. Install a stop motion device to ensure safety. Not doing so might result in a minor injury. (A holding brake is not a stop motion device designed to ensure safety.) Be sure to use a specified type of braking resistor/regenerative braking unit.

Page 44 2-2 Wiring Cable Length Between Inverter and Motor Use a cable of 50 m or less between the Inverter and the motor. If the cable length is increased, the stray capacitance between the Inverter outputs and the ground is increased proportionally. An increase in stray capacitance causes high-frequency leakage current to increase, affecting the current detector in the Inverter's output unit and peripheral devices.
