Wire Size and Torque Specifications
WARNING! Fire hazard. Tighten all terminal screws to the specified tightening torque. Loose electrical connections could result in
death or serious injury by fire due to overheating of electrical connections. Improperly tightened terminal screws can also cause
erroneous equipment operation.
Select appropriate wire type and gauges from Table 17. For simpler and more reliable wiring, use crimp ferrules on the
wire ends. Refer to Table 18 for ferrule terminal types and sizes.
Table 17 Wire Gauges and Torque Specifications
Ferrule-Type Wire Terminals
Yaskawa recommends using CRIMPFOX 6, a crimping tool manufactured by PHOENIX CONTACT, to prepare wire
ends with insulated sleeves before connecting to the drive. Refer to Table 18 for dimensions.
