interruption to avoid an unexpected restart (if operation is set to be continued in the processing selection function after momentary power interruption is reset). Doing so may result in injury.

WARNING Provide a separate emergency stop switch because the STOP Key on the Operator

is valid only when function settings are performed. Not doing so may result in injury.

WARNING Be sure to confirm that the RUN signal is turned OFF before turning ON the power

supply, resetting the alarm, or switching the LOCAL/REMOTE selector. Doing so while the RUN signal is turned ON may result in injury.

Caution Be sure to confirm permissible ranges of motors and machines before operation be-

cause the Inverter speed can be easily changed from low to high. Not doing so may result in damage to the product.

Caution Provide a separate holding brake when necessary. Not doing so may result in injury.

Caution Do not perform a signal check during operation. Doing so may result in injury or dam-

age to the product.

Caution Do not carelessly change settings. Doing so may result in injury or damage to the

product.

Maintenance and Inspection Precautions

WARNING Do not touch the Inverter terminals while the power is being supplied.

WARNING Maintenance or inspection must be performed only after turning OFF the power

supply, confirming that the CHARGE indicator (or status indicators) is turned OFF, and after waiting for the time specified on the front cover. Not doing so may result in electrical shock.

H Installation Direction and Dimensions

• Install the Inverter under the following conditions.

Ambient temperature for operation (panel-mounting): –10°C to 50°C

Humidity: 95% or less (no condensation)

• Install the Inverter in a clean location free from oil mist and dust. Alternatively, install it in a totally enclosed panel that is completely protected from floating dust.

• When installing or operating the Inverter, always take special care so that metal powder, oil, water, or other foreign matter does not get into the Inverter.

• Do not install the Inverter on inflammable material such as wood.

H Direction

• Install the Inverter on a vertical surface so that the characters on the nameplate are oriented upward.

H Dimensions

• When installing the Inverter, always provide the following clearances to allow normal heat dissipation from the Inverter.

W = 30 mm min.

Inverter

100 mm min. Air

SideInverter Inverter

100 mm min. Air

H Ambient Temperature Control

• To enhance operation reliability, the Inverter should be installed in an environment free from extreme temperature changes.

• If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 50°C. The life of the built-in electrolytic capacitors of the Inverter is prolonged by maintaining the internal air temperature as low as possible.

• The surface temperature of the Inverter may rise approximately 30°C higher than the ambient temperature. Be sure to keep away equipment and wires from the Inverter as far as possible if the equipment and wires are easily influenced by heat.
