Environment
Pollution degree 2 or less
Install the drive in an area without:
• Oil mist, corrosive or flammable gas, or dust
• Metal powder, oil, water, or other unwanted materials
Surrounding Area • Radioactive materials or flammable materials, including wood
• Harmful gas or fluids
• Salt
• Direct sunlight
Keep wood and other flammable materials away from the drive.
1000 m (3281 ft.) maximum
Note:
Derate the output current by 1% for each 100 m (328 ft.) to install the drive in altitudes between 1000 m to 4000 m (3281 ft. to 13123 ft.).
Altitude
It is not necessary to derate the rated voltage in these conditions:
• When installing the drive at 2000 m (6562 ft.) or lower
• When installing the drive between 2000 m to 4000 m (6562 ft. to 13123 ft.) and grounding the neutral point on the power supply.
Contact the manufacturer or your nearest sales representative when not grounding the neutral point.
• 10 Hz to 20 Hz: 1 G (9.8 m/s
• 20 Hz to 55 Hz:
Vibration
Models 2004 to 2211, 4002 to 4168: 0.6 G (5.9 m/s
Models 2257 to 2415, 4208 to 4675: 0.2 G (2.0 m/s
Install the drive vertically for sufficient cooling airflow.

Removing the Covers

DANGER
Electrical shock Hazard. Disconnect the power to the drive and wait for the charge indicator LED to go off,
then remove the covers. Failure to obey could cause death or serious injury.

Electrical Installation

DANGER Electrical Shock Hazard. 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, measure for dangerous voltages to make sure that the
drive is safe. If you do work on the drive when it is energized, it will cause serious injury or death from electrical shock.
WARNING 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 terminals for the drive only for their intended purpose. Refer to the technical
manual for more information about the I/O terminals. Wiring and grounding incorrectly or modifying the cover may damage the
equipment or cause injury.

Standard Connection Diagram

Wire the drive as specified by
WARNING
Sudden Movement Hazard. Set the MFDI terminal parameters before you close 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 you use a 3-Wire sequence, set A1-03 = 3330 [Init Parameters = 3-Wire
Initialization] and make sure that b1-17 = 1 [RUN@PowerUp Selection = Disregard RUN] (default). If you do not correctly set
the drive parameters for 3-Wire operation before you energize the drive, the motor can suddenly rotate in reverse when you
energize the drive. This can cause serious injury or death.
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.
