SYSDRIVE MX2 Series USER'S MANUAL (3G3MX2-Axxxx)

Design
Note 1: Applicable devices assume use of a standard 3-phase, 4-pole motor.
Note 2: Select an applicable circuit breaker by also considering the cutoff capacity. (Use an inverter type.)
Use one circuit breaker for one inverter according to the applications shown in the above table.
Note 3: If the wiring distance exceeds 20 m, the power cable size must be increased.
Note 4: A H-IV wire (75°C) is recommended.
Note 5: Use an earth leakage breaker (ELB) to ensure safety.
Note 6: To meet the UL standards, always insert a UL-standard fuse of class J type on the power supply
side.
Note 7: Use a ground wire with a larger diameter than that of the power cable shown above.
Note 8: Tighten the terminal-block screws with the specified torque. If the screws are not tightened
securely, short-circuiting or fire may occur. Excessive tightening may cause damage to the
terminal block or the Inverter.
Note 9: Choose the sensitivity current of the earth leakage breaker (ELB) depending on the total distance
between the Inverter and the power supply, and the Inverter and the motor. Also, use an earth
leakage breaker of time-delay type. Use of a high-speed type may result in malfunction.
Note 10: If a CV wire is used and routed through a metal pipe, the leakage current becomes 30 mA/km.
Note 11: Due to the higher specific inductive capacity of the IV wire, the leakage current increases about
eight times. Accordingly, use a wire with a sensitivity current of eight times the applicable level
shown in the table below. Also, use a CV wire if the total wiring length exceeds 100 m.
