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 67 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 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: The minimum load for the multi-function relay output MA-MB-MC is 10 mA.

WARNING! Sudden Movement Hazard. Do not close the wiring for the control circuit unless the multifunction
input terminal parameter is properly set (S5 for 3-Wire; H1-05 = “0”). Improper sequencing of run/stop circuitry
could result in death or serious injury from moving equipment.
WARNING! Sudden Movement Hazard. Ensure start/stop and safety circuits are wired properly and in the
correct state before energizing the drive. Failure to comply could result in death or serious injury from moving
equipment. When programmed for 3-Wire control, a momentary closure on terminal S1 may cause the drive
to start.
WARNING! When 3-Wire sequence is used, set the drive to 3-Wire sequence before wiring the control
terminals and ensure parameter b1-17 is set to 0 (drive does not accept a run command at power up (default).
If the drive is wired for 3-Wire sequence but set up for 2-Wire sequence (default) and if parameter b1-17 is
set to 1 (drive accepts a Run command at power up), the motor will rotate in reverse direction at power up of
the drive and may cause injury.
Figure 3.2 illustrates an example of a 3-Wire sequence.

Refer to diagrams in this section for the Main Circuit wiring connections. Connections may
vary based on drive capacity. The main circuit DC power supply powers the control circuit.
NOTICE: Do not use the negative DC bus terminal “-” as a ground terminal. This terminal is at high voltage
DC potential. Improper wiring connections could result in damage to the drive.
