Yaskawa A1000 6-Phase/12-Pulse Input - Manual (Page 15)

3 Electrical Installation
u Standard Connection Diagram
Connect the drive and peripheral devices as shown in Figure 4 . It is possible to set and run the drive via the digital operator
without connecting digital I/O wiring.
WARNING! Fire Hazard - Drive Short-Circuit Current Rating. Install adequate branch circuit protection according to applicable local codes
and this manual. Failure to comply could result in fire and damage to the drive or injury to personnel. The device is suitable for use on a
circuit capable of delivering not more than 100,000 RMS symmetrical amperes, 480 Vac maximum (400 V class), when protected by branch
circuit protection devices specified in this manual.
NOTICE: Route motor leads U/T1, V/T2, and W/T3 separate from all other leads to reduce possible interference related issues. Failure to
comply may result in abnormal operation of drive and nearby equipment.
NOTICE: Equipment Hazard. Standard motors used with PWM drives may experience winding failures due to surge voltages when input
line voltage is greater than 480 V or motor wire distance is greater than 100 meters. Select a motor design with insulation tolerant of surge
voltages, such as drive-rated motor for use with PWM drives. Failure to comply could lead to motor winding failure.
Note: The minimum load for the relay outputs M1-M2, M3-M4, M5-M6, and MA-MB-MC is 10 mA.
