3.1 Standard Connection Diagram
3.1 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 51 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 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. 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.
