3.3 Main Circuit Wiring
74 YASKAWA SIEPC71061753C GA500 Technical Manual
■ Main Circuit Wire Gauges and Tightening Torques
WARNING! Electrical Shock Hazard. Make sure that the protective ground wire complies with technical standards and local
safety regulations. The EN 61800-5-1:2007 standard specifies that you must wire the power supply to automatically de-energize
when the protective ground wire disconnects. If you turn on the internal EMC filter, the leakage current of the drive will be more
than 3.5 mA. Use the closed-loop crimp terminal to connect a protective ground wire that has a minimum cross-sectional area of
10 mm
2
(copper wire). If you do not obey the standards and regulations, it can cause serious injury or death.
Note:
• The recommended wire gauges are based on drive continuous current ratings with 75 °C (167 °F) 600 V class 2 heat-resistant indoor
PVC wire. Assume these conditions:
–Ambient temperature: 40 °C (104 °F) maximum
–Wiring distance: 100 m (3281 ft) maximum
–Normal Duty rated current value
• Use terminals +1, +2, -, B1, and B2 to connect peripheral options, for example a DC reactor or a braking resistor. Do not connect other
items to these terminals.
• Refer to the instruction manual for each device for recommended wire gauges to connect peripheral devices or options to terminals +1,
+2, -, B1, and B2. Contact Yaskawa or your nearest sales representative if the recommended wire gauges for the peripheral devices or
options are out of the range of the applicable gauges for the drive.
• When you use crimp ferrules on the wire ends, contact Yaskawa or your nearest sales representative.
