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 55 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: Do not connect AC control circuit ground to drive enclosure. Improper drive grounding can cause control circuit malfunction.
NOTICE: The minimum load for the multi-function relay output MA-MB-MC is 10 mA.
