3.3 Main Circuit Wiring
72 YASKAWA SIEPC71061737B GA800 Drive Technical Reference
• Refer to “ Yaskawa AC Drive Option Braking Unit, Braking Resistor Unit Instruction Manual (TOBPC72060001) ”
for information about wire gauges and tightening torques to connect braking resistor units or braking units.
•
Use ter1 and - to connect a regenerative converter or regenerative unit.
WARNING! Fire Hazard. Do not connect a braking resistor to ter1 or -. Use terminals B1 and B2 for the braking resistor
connections. If you connect a braking resistor to the incorrect terminals, it can cause damage to the drive and braking circuit and
serious injury or death.

Wire Gauge and Torque Specifications for UL Listing
WARNING! Electrical Shock Hazard. Make sure that the protective ground wire conforms to 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
10 mm
2 (copper wire) or 16 mm 2 (aluminum wire). 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 in drive models 4414 to 4720.
Refer to Three-Phase 200 V Class on page 72 and Three-Phase 400 V Class on page 77 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 2 heat-resistant indoor PVC
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
•
Use ter1, +2, +3, -, B1, and B2 to connect a peripheral option such as a DC link choke 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 ter1, +2,
+3, -, 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.
