disconnects the inverter and reconnects the inverter to the input supply power for the

purpose of starting and stopping the motor.

A noise filter may be installed to reduce the effect of electromagnetic interference.

Otherwise nearby electronic equipment may be affected.

In cases with input voltage unbalances, install an AC input reactor.

Power Factor capacitors and generators may become overheated and damaged due to

harmonics created by the inverter.

Use an insulation-rectified motor or take measures to suppress the micro surge voltage

when driving 460V class motor with inverter. A micro surge voltage attributable to wiring

constant is generated at motor terminals, and may deteriorate insulation and damage

motor.

Before operating unit and prior to user programming, reset user parameters to default

settings.

The Inverter can be set to operate a motor at high-speeds. Verify the speed capability of

motor and machinery prior to operating inverter.

Holding torque is not produced when using the DC-Brake function. Install separate

equipment when holding torque is required.

(5) Fault prevention precautions

If required, provide a safety backup such as an emergency mechanical brake to prevent

any hazardous conditions if the inverter fails during operation.

(6) Maintenance, inspection and parts replacement

Do not megger (hi-pot or insulation resistance) test the power or control circuit of the

inverter.

Refer to Chapter 8 for periodic inspection and parts replacement details.

(7) Disposal

Handle the inverter as an industrial waste when disposing of it.

(8) General instructions
