u Standard Connection Diagram
Connect the drive and peripheral devices as shown in Figure i.12 . It is possible to set and run the drive via the digital operator
without connecting digital I/O wiring.
NOTICE: Inadequate wiring could result in damage to the drive. Install adequate branch circuit protection per applicable codes. The drive
is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical amperes, 240 Vac maximum (200 V class),
480 Vac maximum (400 V class: 4E oooo and 4Woooo), and 500 Vac maximum (400 V class: 4Aoooo and 4Poooo) when
protected by branch circuit protection devices specified in this document.
NOTICE: Do not connect AC control circuit ground to drive enclosure. Improper drive grounding can cause control circuit malfunction.
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: Correctly set Sink/Source jumper S3 for internal power supply. Failure to comply may result in damage to the drive.
Note: The minimum load for the relay outputs M1-M2, M3-M4, M5-M6, and MA-MB-MC is 10 mA.
