Crimp Ferrules
Attach an insulated sleeve to the wire when connecting crimp ferrules. Refer to
external dimensions and model numbers of the crimp ferrules.
Yaskawa recommends the CRIMPFOX 6 crimping tool from PHOENIX CONTACT.

Line Voltage Drop
WARNING Electrical Shock Hazard. The leakage current of drive models 4389A to 4675A, 2xxxB/C and 4xxxB/C is more
than 3.5 mA. The IEC/EN 61800-5-1: 2007 standard specifies that users must wire the power supply to automatically turn off
when the protective ground wire disconnects. Users can also connect a protective ground wire that has a minimum cross-
sectional area of 10 mm 2 (copper wire) or 16 mm
injury.
Be sure to 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) =

Dynamic Braking Precautions
Connect braking units to drives with these conditions:
• Models with built-in braking transistors use terminals B1 and -
• Models without built-in braking transistors use terminals +3 and -.
NOTICE Review the Braking Unit and Braking Resistor Unit Installation Manual TOBPC72060001 for wire gauge and
tightening torque information before connecting a dynamic braking option to the drive. Failure to obey can cause damage to the
drive and braking circuit.
Connect a regenerative converter or regenerative unit with terminals +1 and -.
NOTICE Do not connect a braking resistor to terminals +1 or -. Failure to obey can cause damage to the drive circuitry.
