Not doing so may result in a serious injury due to an electric shock.

Do not touch the surface of the PG Board or terminals, and do not remove the encoder wire or the

PG Board while the power is being supplied.

Doing so may result in a serious injury due to an electric shock or fire.

Turn off the input power of the Inverter and wait for more than 10 minutes before putting on or taking

off the PG Board, changing the setting / wiring or conducting inspection.

Not doing so may result in a serious injury due to an electric shock.

Place covers on the openings or take other precautions to make sure that no metal objects such as

Do not dismantle, repair or modify the product. Doing so may result in an injury.

WARNING

CAUTION

Precautions for Safe Use

Installation and Storage

Do not store or use the product in the following places.

• Locations subject to direct sunlight.

• Locations subject to ambient temperature exceeding the specifications.

• Locations subject to relative humidity exceeding the specifications.

• Locations subject to condensation due to severe temperature fluctuations.

• Locations subject to corrosive or flammable gases.

• Locations subject to exposure to combustibles.

• Locations subject to dust (especially iron dust) or salt.

• Locations subject to exposure to water, oil, or chemicals.

Transportation, Installation, and Wiring

Observe the following instructions during transportation, installation, and wiring.

• Do not drop or apply a strong impact on the product. Doing so may result in damaged parts or

malfunction.

• Connect the PG Board to the Inverter tightly with the provided fixing screws.

Tighten securely the terminal screws for the encoder wire on the PG Board.

Tightening torque : 0.9 N⋅m (1.0 N⋅m max.)

• Be sure to use the provided ferrite cores. Fix the ferrite cores on the wire or take appropriate

measures so that the ferrite cores will not cover the shield coating of the wire.

Not doing so may cause the Inverter to malfunction.

• Fix the shielding wire properly or take appropriate measures so that the wire will not be weighed

down.

Not doing so may result in shielding wire breakage due to the weight of the ferrite cores.

• Check whether the motor rotation direction is correct, and unusual sound or vibration occurs

during operation.

Maintenance and Inspection

Be sure to confirm safety before conducting maintenance, inspection or parts replacement.

Precautions for Correct Use

Rated Voltage

Confirm that the power voltage for the encoder is the same as the rated voltage (+5 V DC) of the

product.
