*1 Remove the insulator from the tips of wires to the length shown in "Wire Stripping Length."
*2 When using wire with AWG 8 or higher, tighten to a tightening torque of 4.1 to 4.5 N∙m (36 to 40 lb∙in.).

Closed-Loop Crimp Terminals
Yaskawa recommends closed-loop crimp terminals from J.S.T.MFG. Co., Ltd., and insulation caps from Tokyo
DIP Co., Ltd.
Contact Yaskawa or your nearest sales representative for details on selection of closed-loop crimp terminals and
insulation caps.
Follow local standards concerning appropriate wire gauges in the region where the drive is used.
Note:
Use only insulated crimp terminals or crimp terminals with insulation tubing to comply with UL standards. Use UL-Listed, vinyl-coated
insulated copper wires for operation with a continuous maximum allowable temperature of 75 °C at 600 V.

Factory Recommended Branch Circuit Protection
To maintain compliance with UL61800-5-1, execute branch circuit protection when a short occurs in the internal
circuit. Yaskawa recommends connecting a semiconductor protective type fuses to the input side for branch circuit
protection. Refer to Table 4.17
NOTICE: Do not energize the power or operate equipment soon after a fuse blows or the circuit breaker (ELCB) trips. Check the
condition of cable wiring and peripheral devices to identify the root cause. If the root cause cannot be determined, do not turn on
the power or operate equipment. Contact Yaskawa Support immediately.
• 200 V class
The drive is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical amperes
and 240 Vac during short circuit of the power supply, when protected by fuses as specified in this document.
• 400 V class
The drive is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical amperes
and 480 Vac during short circuit of the power supply, when protected by fuses as specified in this document.
Drive's built-in short circuit protection does not provide branch circuit protection. Branch circuit protection must
be provided in accordance with the NEC (National Electric Code) the CEC (Canadian Electric Code, Part I), and
any additional local codes.
