Electrical Installation
DANGER
Electrical Shock Hazard. Do not examine, connect, or disconnect wiring on an energized drive. Before
servicing, disconnect all power to the equipment and wait for the time specified on the warning label at a minimum. The internal
capacitor stays charged after the drive is de-energized. The charge indicator LED extinguishes when the DC bus voltage
decreases below 50 Vdc. When all indicators are OFF, remove the covers before measuring for dangerous voltages to make
sure that the drive is safe. Failure to obey will cause death or serious injury.
DANGER
Electrical Shock Hazard. Make sure that all electrical connections are correct and install all drive covers
before energizing the drive. Use terminals for their intended function only. Incorrect wiring or ground connections, and incorrect
repair of protective covers can cause death or serious injury.
WARNING
Electrical Shock Hazard. Correctly ground the drive before turning on the EMC filter switch. Failure to obey
can cause death or serious injury.
WARNING
Electrical Shock Hazard. Use the drive terminals only for their intended function. Refer to the drive Technical
Manual for more information about I/O terminals. Incorrect wiring, incorrect grounding, and unsatisfactory repair of the
protective cover could cause death or serious injury and damage to the drive.

Standard Connection Diagram
Wire the drive as shown in the following figure. If the drive is run using the keypad, the motor can be run by main
circuit wiring.
WARNING
Sudden Movement Hazard. Set the multi-function input terminal parameters before closing the control circuit
wiring. Incorrect Run/Stop circuit sequence settings can cause death or serious injury from moving equipment.
WARNING
Sudden Movement Hazard. Correctly wire the start/stop and safety circuits before energizing the drive.
Momentarily closing a digital input terminal can start a drive that is programmed for 3-Wire control. Failure to obey can cause
death or serious injury from moving equipment.
WARNING
Sudden Movement Hazard.
When using a 3-Wire sequence:
• Set the drive for 3-Wire sequence.
• Set b1-17 = 0 [Run Command at Power Up = Disregard Existing RUN Command]
• Wire the drive for 3-Wire sequence.
The motor can rotate in reverse when energizing the drive if these three conditions are true:
• The drive is wired for 3-Wire sequence.
• The drive is set for a 2-Wire sequence (default).
• b1-17 = 1 [Accept Existing RUN Command]
Failure to obey can cause death or serious injury from moving equipment.
WARNING
Sudden Movement Hazard. Make sure that the drive I/O signals and external sequence are correct before
entering the Application Preset function. Entering the Application Preset function or setting A1-06
≠
0 [Application Preset
≠
General-purpose] changes the drive I/O terminal functions and can cause sudden equipment operation. Failure to obey can
cause death or serious injury.
NOTICE
Fire Hazard. Install sufficient branch circuit short circuit protection as specified by applicable codes and this
manual. The drive is suited for circuits that supply not more than 100,000 RMS symmetrical amperes, 240 Vac maximum (200 V
Class), 480 Vac maximum (400 V Class). Failure to obey can cause death or serious injury.
NOTICE
When the input voltage is 440 V or higher or if the wiring distance is longer than 100 m (328 ft.) be sure to use
a drive duty motor or carefully monitor the motor insulation voltage. Failure to obey can cause damage to the motor insulation.
NOTICE
Do not connect the AC control circuit ground to the drive enclosure. Failure to obey can cause incorrect
control circuit operation.
