3.2 Standard Connection Diagram
Connect the drive and peripheral devices as shown in Figure 3.1. It is possible to run the
drive via the digital operator without connecting digital I/O wiring. This section does not
discuss drive operation; Refer to Start-Up Programming & Operation on page 87 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 30,000 RMS symmetrical amperes, 240 Vac maximum (200 V Class) and 480 Vac
maximum (400 V Class).
NOTICE: When the input voltage is 480 V or higher or the wiring distance is greater than 100 meters, pay
special attention to the motor insulation voltage or use an inverter duty motor. Failure to comply could lead
to motor insulation breakdown.
NOTICE: Do not connect the AC control circuit ground to the drive enclosure. Improper drive grounding can

cause the control circuit to malfunction.
NOTICE: The minimum load for the multi-function relay output MA-MB-MC is 10 mA (reference value). If a
circuit requires less than 10 mA, 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.
