■ Wire Selection
Select the correct wires for main circuit wiring.
Refer to Main Circuit Wire Gauges and Tightening Torques on page 83 for wire gauges and tightening torques as
specified by European standards.
Refer to Wire Gauge and Torque Specifications for UL Listing on page 30 for wire gauges and tightening torques as
specified by UL standards.
Wire Selection Precautions
WARNING
Electrical Shock Hazard. Make sure that the protective ground wire complies with technical standards and local
safety regulations. The IEC/EN 61800-5-1:2007 standard specifies that you must wire the power supply to automatically de-
energize when the protective ground wire disconnects. You can also connect a protective ground wire that has a minimum cross-
sectional area of 10mm
2
(copper wire) or 16 mm
2
(aluminum wire). For drive models on which you cannot use a protective ground
wire of 10 mm
2
or more, install two protective ground wires that have the same cross-sectional area. If you do not obey the
standards and regulations, it can cause serious injury or death. The leakage current of the drive will be more than 3.5 mA.
