The interior parts of the Inverter will be damaged if voltage is applied to the output terminals.
The Inverter can be damaged or internal parts burnt if these devices are connected.
iii
• Do not connect electromagnetic switches or contactors to the output circuits.
If a load is connected while the Inverter is operating, surge current will cause the overcurrent protection circuit inside the
Inverter to operate.
Setting User Constants
• Disconnect the load (machine, device) from the motor before performing rotational autotuning.
The motor may turn, possibly resulting in injury or damage to equipment. Also, motor constants cannot be correctly set
with the motor attached to a load.
• Stay clear of the motor during rotational autotuning.
The motor may start operating suddenly when stopped, possibly resulting in injury.
Trial Operation
• Check to be sure that the front cover is attached before turning ON the power supply.
An electric shock may occur.
• Do not come close to the machine when the fault reset function is used. If the alarmed is cleared,
the machine may start moving suddenly.
Also, design the machine so that human safety is ensured even when it is restarted.
Injury may occur.
• Provide a separate emergency stop switch; the Digital Operator STOP Key is valid only when its
function is set.
Injury may occur.
• Reset alarms only after confirming that the RUN signal is OFF.
Injury may occur.
CAUTION
CAUTION
WARNING
CAUTION
• Don't touch the radiation fins (heatsink), braking resistor, or Braking Resistor Unit. These can
become very hot.
Otherwise, a burn injury may occur.
• Be sure that the motor and machine is within the applicable ranges before starting operation.
Otherwise, an injury may occur.
• Provide a separate holding brake if necessary.
Always construct the external sequence to confirm that the holding brake is activated in the event
of an emergency, a power failure, or an abnormality in the Inverter.
Failure to observe this caution can result in injury.
• If using an Inverter with an elevator, take safety measures on the elevator to prevent the elevator
from dropping.
Failure to observe this caution can result in injury.
• Don't check signals while the Inverter is running.
Otherwise, the equipment may be damaged.
• Be careful when changing Inverter settings. The Inverter is factory set to suitable settings.
Otherwise, the equipment may be damaged.
iv
Maintenance and Inspection
• Do not touch the Inverter terminals. Some of the terminals carry high voltages and are extremely
dangerous.
Doing so can result in electric shock.
• Always have the protective cover in place when power is being supplied to the Inverter. When
attaching the cover, always turn OFF power to the Inverter through the MCCB.
Doing so can result in electric shock.
• After turning OFF the main circuit power supply, wait until the CHARGE indicator light goes out
before performance maintenance or inspections.
The capacitor will remain charged and is dangerous.
• Maintenance, inspection, and replacement of parts must be performed only by authorized personnel.
Remove all metal objects, such as watches and rings, before starting work. Always use grounded tools.
Failure to heed these warning can result in electric shock.
• A CMOS IC is used in the control board. Handle the control board and CMOS IC carefully. The

NEMA 1 Type 1)
Fig 1.3 Inverter Specifications
Open Chassis Type (IEC IP00)
Protected so that parts of the human body cannot reach electrically charged parts from the front when the
Inverter is mounted in a control panel.
Enclosed Wall-mounted Type (IEC IP20, NEMA 1 Type 1)
The Inverter is structured so that the Inverter is shielded from the exterior, and can thus be mounted to the
interior wall of a standard building (not necessarily enclosed in a control panel). The protective structure conforms to the standards of NEMA 1 in the USA.
Top protective cover must be installed to conform with IEC IP20 and NEMA 1 Type 1 requirements. Refer to

Protection covers are attached to the top and bottom of the Inverter. Be sure to remove the protection covers
before installing a 200 or 400 V Class Inverter with an output of 15 kW or less in a panel.
Observe the following precautions when mounting the Inverter.
• Install the Inverter in a clean location free from oil mist and dust. It can be installed in a totally enclosed
panel that is completely shielded 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 combustible material, such as wood.
• Install the Inverter in a location free from radioactive materials and combustible materials.
• Install the Inverter in a location free from harmful gasses and liquids.
• Install the Inverter in a location without excessive oscillation.
• Install the Inverter in a location free from chlorides.

Controlling the Ambient Temperature
To enhance the reliability of operation, the Inverter should be installed in an environment free from extreme
temperature increases. 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 45°C.
Protecting the Inverter from Foreign Matter
Place a cover over the Inverter during installation to shield it from metal power produced by drilling.
Always remove the cover from the Inverter after completing installation. Otherwise, ventilation will be
reduced, causing the Inverter to overheat.
