Always connect power to the L1/R, L2/S, and L3/T main circuit power terminals on the drive. Connecting power toanother terminal will damage the drive. Check that the input voltage is within the maximum allowable voltage markedon the nameplate, etc.2. Always wire the ground terminal to ground to prevent problems such as fire or electric shock and to minimize noise.3. Use a reliable crimp terminal for connection between a power terminal and a power wire.4. After terminating the wiring connection, confirm the following:a. Confirm that the connection is correct.b. Confirm that all necessary connections have been made.c. Confirm that there is no short-circuit or ground fault between the terminals and wire.5. Connection modification after power-on.The smoothing capacitor in the direct current portion of the main circuit cannot be discharged immediately after thepower is turned off. To insure safety, use a multimeter to check that the direct current (DC) voltage is lowered to thesafety range (25V DC or less) after the charge lamp goes off. Also, confirm that the voltage is zero before short-circuiting. The residual voltage (electric charge) may cause sparks.WARNINGAlways connect a ground wire. Electric shock or fire may result. Ensure that a trained specialistperforms all wiring. Confirm that the power is turned off (open) before beginning any wiring operations.Electrical shock may result.
