Wire Gauge and Torque Specifications for UL Listing
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.
Refer to
Three-Phase 208 V Class Wire Gauges and Torques on page 32
and
Three-Phase 480 V Class Wire Gauges
for the recommended wire gauges and tightening torques of the main circuit terminals.
Note:
The recommended wire gauges are based on drive continuous current ratings with 75 °C (167 °F) 600 V class copper wire. Assume these
conditions:
•
Ambient temperature: 40 °C (104 °F) or lower
•
Wiring distance: 100 m (3281 ft) or shorter
•
Normal Duty Rated current value
