Wire Gauges and Tightening Torques
Wire gauge and torque specifications are listed in Table 8.10. For simpler and more reliable wiring, use crimp ferrules on
the wire ends. Refer to the option manuals for
the wire size and torque specifications of other options.
Table 8.10 Wire Gauges and Tightening Torques
Crimp Terminals
YASKAWA recommends using CRIMPFOX 6 by Phoenix Contact or equivalent crimp terminals with the specifications
listed in Table 8.11 for wiring to ensure proper connections.
Note: Properly trim wire ends so loose wire ends do not extend from the crimp terminals.
Table 8.11 Crimp Terminal Sizes
6. Route the option wiring.
Depending on the drive model, some drives may require routing the wiring through the side of the front cover to
the outside. For drive models CIMR-A2A0004 through 2A0040 and 4A0002 through 4A0023, cut out the
perforated openings on the left side of the drive front cover as shown in Figure 8.14-A and leave no sharp edges
to damage wiring. 
Route the wiring inside the enclosure as shown in Figure 8.14-B for drive models CIMR-A2A0056 through
2A0415 and 4A0031 through 4A1200 that do not require routing through the front cover.
