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 users must wire
the power supply to automatically turn off 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. You can also 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.
WARNING
Electrical Shock Hazard. Only connect factory-recommended devices or circuits to drive
terminals B1, B2, -, +1, and +2. Do not connect AC power to these terminals. Incorrect wiring can cause damage
to the drive and serious injury or death from fire.
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
•
Refer to the instruction manual for each device for recommended wire gauges to connect peripheral devices or options
to ter1, +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.
Wire Selection Precautions
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 these closed-loop crimp terminals or equivalent to connect a protective ground wire that
has a minimum cross-sectional area of 10 mm
2
(copper wire).
• 8-4NS from JST Mfg. Co., Ltd.
• R8-4S from NICHIFU Co., Ltd.
• P10-8R from PANDUIT Corp.
If you do not obey the standards and regulations, it can cause serious injury or death.
Think about line voltage drop before selecting wire gauges. Select wire gauges that drop the
voltage by 2% or less of the rated voltage. Increase the wire gauge and the cable length when the
risk of voltage drops increases. Calculate line voltage drop with this formula:
Line voltage drop (V) =
× wire resistance (Ω/km) × wiring distance (m) × motor rated
current (A) × 10

Precautions during Wiring
•
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.
•
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.
