Connect the drive and peripheral devices as shown in Figure i.5. It is possible to set and run the drive via the HOA keypad
without connecting digital I/O wiring.
WARNING! Fire Hazard. Install adequate branch circuit protection according to applicable local codes and this manual. Failure to comply
could result in fire and damage to the drive or injury to personnel. The device is suitable for use on a circuit capable of delivering not more
than 100,000 RMS symmetrical amperes 600 Vac maximum (600 V class), when protected by branch circuit protection devices specified
in this manual. Branch circuit protection shall be provided by any of the following: Non-time delay Class J, T, or CC fuses sized at 300% of
the drive input rating, or Time delay Class J, T, or CC fuses sized at 175% of the drive input rating, or MCCB sized at 200% maximum of
the drive input rating.
WARNING! Sudden Movement Hazard. Do not close the wiring for the control circuit unless the multifunction input terminal parameters are
properly set. 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! Sudden Movement Hazard. When using a 3-Wire sequence, set the drive to 3-Wire sequence prior to wiring the control terminals
and set parameter b1-17 to 0 so the drive will not accept a Run command at power up (default). If the drive is wired for a 3-Wire sequence
but set up for a 2-Wire sequence (default), and parameter b1-17 is set to 1 so the drive accepts a Run command at power up, the motor
will rotate in reverse direction at drive power up and may cause injury.
WARNING! Sudden Movement Hazard. Confirm the drive I/O signals and external sequence before executing the application preset
function. Executing the application preset function or setting A1-06 ≠ 0 will change the drive I/O terminal functions and may cause unexpected
equipment operation. Failure to comply may cause death or serious injury.
NOTICE: When using the automatic fault restart function with wiring designed to shut off the power supply upon drive fault, make sure the
drive does not trigger a fault output during fault restart (L5-02 = 0, default). Failure to comply will prevent the automatic fault restart function
from working properly.
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: Route motor leads U/T1, V/T2, and W/T3 separate from all other leads to reduce possible interference related issues. Failure to
comply may result in abnormal operation of drive and nearby equipment.
Note: The minimum load for the relay outputs M1-M2, M3-M4, M5-M6, and MA-MB-MC is 10 mA.
