i.1 Preface
Do not remove covers or touch circuit boards while the power is on.
Failure to comply could result in death or serious injury.
Do not turn on the power for only the Harmonic Filter Module and Stand-Alone EMC Filter.
Failure to comply could result in death or serious injury. The output terminals remain charged even after the power supply
is turned off. Always connect the Harmonic Filter Module and Stand-Alone EMC Filter as shown in the standard connection
diagram and turn on the Harmonic Filter Module and Stand-Alone EMC Filter according to the diagram.

Compliance for Models 4
Make sure the protective earthing conductor complies with technical standards and local safety regulations.
Because the leakage current exceeds 3.5 mA in models 4o0302 and larger, IEC/EN 61800-5-1 states that either the power
supply must be automatically disconnected in case of discontinuity of the protective earthing conductor or a protective
earthing conductor with a cross-section of at least 10 mm
in death or serious injury.
Always use appropriate equipment for Ground Fault Circuit Interrupters (GFCIs).
The drive can cause a residual current with a DC component in the protective earthing conductor. Where a residual current
operated protective or monitoring device is used for protection in case of direct or indirect contact, always use a type B GFCI
according to IEC/EN 60755.
Do not use an improper voltage source.
Failure to comply could result in death or serious injury by fire. Verify that the rated voltage of the drive matches the voltage
of the incoming power supply before applying power.
Do not use improper combustible materials for the drive and harmonic filter module.
Failure to comply could result in death or serious injury by fire. Attach the drive and harmonic filter module to metal or other
noncombustible material.
Tighten all terminal screws to the specified tightening torque.
Loose electrical connections could result in death or serious injury by fire due to overheating of electrical connections.
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, 240 Vac
maximum (200 V class), 480 Vac maximum (400 V class: 4Eoooo and 4Woooo), and 500 Vac maximum (400 V
class: 4Aoooo and 4Poooo) when protected by branch circuit protection devices specified in this document.
Do not use this drive in lifting applications without installing external safety circuitry to prevent accidental dropping
of the load. The drive does not possess built-in load drop protection for lifting applications.
Failure to comply could result in death or serious injury from falling loads.
Install electrical and/or mechanical safety circuit mechanisms independent of drive circuitry.
Do not carry the drive by the front cover.
Failure to comply may result in minor or moderate injury from the main body of the drive falling.
