u Standard Connection Diagram
Connect the drive and peripheral devices as shown in Figure i.9 . It is possible to run the drive via the digital operator without
connecting digital I/O wiring. Refer to Start-Up Programming and Operation on page 58 for instructions on operating the
drive
NOTICE: Inadequate branch short circuit protection could result in damage to the drive. Install adequate branch circuit short circuit protection
per applicable codes. The drive is suitable for circuits capable of delivering not more than 31,000 RMS symmetrical amperes, 240 Vac
maximum (200 V Class) and 480 Vac maximum (400 V Class).
NOTICE: When the wiring distance is greater than 100 meters, pay special attention to the motor insulation voltage or use a drive duty
motor. Failure to comply could lead to motor insulation breakdown.
NOTICE: Correctly set Sink/Source jumper S3 for internal power supply. Failure to comply may result in damage to the drive.
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: The minimum load for the multi-function relay output MA-MB-MC is 10 mA. If a circuit requires less than 10 mA (reference value),
connect it to a photocoupler output (P1, P2, PC). Improper application of peripheral devices could result in damage to the photocoupler
output of the drive.
