3.2 Standard Connection Diagram
Connect the drive and peripheral devices as shown in Figure 3.1 . It is possible to set and run the drive via the HOA keypad
without connecting digital I/O wiring.
NOTICE: Inadequate wiring could result in damage to the drive. Install adequate branch circuit short 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: 4Uoooo and 4Poooo)
when protected by branch circuit protection devices specified in this document.
NOTICE: When the input voltage is 440 V or higher or 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: 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.
Note: The minimum load for the relay outputs M1-M2, M3-M4, MD-ME-MF, and MA-MB-MC is 10 mA.
