Electrical Installation

DANGER! Electrical Shock Hazard. Do not inspect, connect, or disconnect any wiring while the drive is energized. Before
servicing, disconnect all power to the equipment and wait for at least the time specified on the warning label. The internal
capacitor remains charged even after the drive is de-energized. The charge indicator LED will extinguish when the DC bus
voltage is below 50 Vdc. When all indicators are OFF, remove the covers and then measure for unsafe voltages to confirm the
drive is safe. Failure to comply will cause death or serious injury.
DANGER! Electrical Shock Hazard. After wiring the drive, safely check that all electrical connects are correct and that all covers
are correctly installed before turning on the power. If the drive is already energized, de-energize the power and wait at least 5
minutes until the Charge LED completely turns off. Remove the front cover and terminal cover to access wiring, circuit boards,
and other parts. Terminals must only be used for their intended purpose. Improper wiring, improper ground connections, and
improper repair of protective covers could result in electric shock, which could lead to equipment damage, injury, and even
death.
WARNING! Electrical Shock Hazard. Properly ground the drive before turning on the EMC filter switch. Failure to comply could
cause death or serious injury.
WARNING! Electrical Shock Hazard. Use the drive terminals only for their intended purpose. Refer to the drive Technical
Manual for more technical information on I/O terminals. Improper wiring, improper grounding, and faulty 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 Figure 2.28. 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 wiring for the control
circuit. Improper sequencing of run/stop circuitry could cause death or serious injury from moving equipment.
WARNING! Sudden Movement Hazard. Properly wire the start/stop and safety circuits before energizing the drive. When
programmed for 3-Wire control, a momentary closure on a digital input terminal could cause the drive to start. Failure to comply
could cause death or serious injury from moving equipment.
WARNING! Sudden Movement Hazard. When using a 3-Wire sequence, set the drive to 3-Wire sequence and set b1-17 = 0
[Run Command at Power Up = Disregard Existing RUN Command] before wiring the control terminals so the drive will not
accept a Run command at power up. The motor may rotate in reverse when the drive is powered up if the drive is wired for a 3-
wire sequence but set up for a 2-wire sequence (default) and b1-17 = 1 [Accept Existing RUN Command]. Failure to comply
could cause death or serious injury from moving equipment.
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 [Application Preset ≠ General-purpose] changes
the drive I/O terminal functions and could cause unexpected equipment operation. Failure to comply could cause death or
serious injury.
WARNING! Fire Hazard. Install adequate branch circuit short circuit protection per applicable codes and this manual. The drive
is suitable for circuits capable of delivering not more than 100,000 RMS symmetrical amperes, 240 Vac maximum (200 V class),
480 Vac maximum (400 V class). Failure to comply could cause death or serious injury.
NOTICE: Pay special attention to the motor insulation voltage or use a drive duty motor when the input voltage is 440 V or
higher or the wiring distance is longer than 100 m (328 ft.) Failure to comply could cause motor insulation breakdown.
NOTICE: Do not connect AC control circuit ground to the drive enclosure. Improper drive grounding could cause control circuit
malfunction.
