3.8 Control Circuit Wiring
YASKAWA ELECTRIC SIEP C710616 38F YASKAWA AC Drive - L1000A Technical Manual 81
■ 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 Ta ble 3.9. For simpler and more reliable wiring, use crimp ferrules on the
wire ends. Refer to Table 3.10 for ferrule terminal types and sizes.
Table 3.9 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 3.1 0 for dimensions.

◆ Wiring the Control Circuit Terminal
This section describes the proper procedures and preparations for wiring the control terminals.
WARNING! Sudden Movement Hazard. Operating a drive with untested emergency circuits could result in death or serious injury.
Verify all drive fast stop circuit wiring and any additional emergency circuits before operating the drive.
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.
WARNING! Electrical Shock Hazard. Do not remove covers or touch the circuit boards while the power is on. Failure to comply could
result in death or serious injury.
WARNING! Electrical Shock Hazard. Before servicing, disconnect all power to the equipment and lock out the power source. Failure to
comply may result in injury from electrical shock. Wait at least five minutes after all indicators are OFF and measure the DC bus voltage
level and main circuit terminals to confirm the circuit is safe before wiring.
WARNING! Sudden Movement and Hazard. Install additional emergency circuits separately from the drive fast stop circuits. Failure to
comply may result in personal injury.
