WARNING Do not come close to the machine immediately after resetting momentary power
!
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.

!
place fans while power is being supplied. Doing so may result in injury, damage to
the product, or malfunction.
Warnings for UL/cUL Marking
• Do not connect or disconnect wiring, or perform signal checks while the power supply is turned ON.
• The Inverter internal capacitor is still charged even after the power supply is turned OFF. To prevent
electrical shock, disconnect all power before servicing the Inverter. Then wait at least one minute after
the power supply is disconnected and all indicators are OFF.
• Do not perform a withstand voltage test on any part of the Inverter. This electronic equipment uses
semiconductors and is vulnerable to high voltage.
• Do not remove the Digital Operator or the blank cover unless the power supply is turned OFF. Never
touch the printed control board (PCB) while the power supply is turned ON.
• The Inverter is not suitable for use on a circuit capable of delivering more than 5,000 RMS symmetrical
amperes, 250 volts maximum (100-V-class Units).
• Take measures against overcurrent, overload, and overheating by using the Motor Protection Settings.
CAUTION
Use 75°C copper wires or equivalent.
Low voltage wires shall be wired with Class I Wiring.

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 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.
H Protecting Inverter from Foreign Matter during Installation
• Place a cover over the Inverter during installation to shield it from metal power produced by drilling.
Upon completion of installation, always remove the cover from the Inverter. Otherwise, ventilation will
be affected, causing the Inverter to overheat.
