injury.
: Improper handling entails danger,
possibly leading to medium-degree
or slight injury or property damage.
CAUTION
Matters classified under may also cause serious
results depending on the situation.
Be sure to strictly observe these safety precautions.
Precautions in general
Covers and safety shields have been removed in the illustrations in the operation manual in order to show the details. Be
sure to return specified covers and safety shields to the original position before operation. Operate the machine in conformity with the operation manual.
The operation manual is subject to change for improvement of
the product, change in specifications, and easy use of the
manual itself. The operation manual No. will be renewed when
a revised edition is issued.
Remodeling of the product by the customer is beyond the scope
of our warrantee, and we will not take responsibility for any
result of remodeling.

1. Confirmation of actual product
CAUTION
!
Do not operate the machine with a damaged inverter or an inverter with some missing parts, otherwise injury may result.
2. Installation
CAUTION
!
Attach the machine to metal or other nonflammables, otherwise a
fire may break out.
Do not place the machine near inflammables, otherwise a fire may
break out.
Do not hold the case at the front of the inverter, otherwise the
inverter may drop, leading to injury.
Do not allow metal chips and other foreign substances to enter,
otherwise a fire may break out.
Install the machine on a floor strong enough to withstand the
weight of the machine according to the operation manual, otherwise the machine may drop, leading to injury.

3. Wiring
!
Check that the input power is OFF before wiring, otherwise an
electric shock or fire may result.
Be sure to install a magnetic circuit breaker (NFB), otherwise a
fire may break out.
Be sure to ground the grounding terminal , otherwise an electric
shock or fire may result. (200 V-class Type D grounding)
Leave the wiring work to an electric engineer.
Be sure to install the machine before wiring, otherwise an electric
shock or fire may result.
When connecting the emergency stop circuit, be sure to check the
operation of the circuit after wiring, otherwise injury may result.
!
DANGER
CAUTION
Do not connect an AV power supply to the output terminals (U, V,
and W), otherwise injury or a fire may result.
Check that the voltage of the AV power supply coincides with the
specified input voltage of the machine, otherwise injury or a fire
may result.
Do not subject the inverter to a withstand voltage test, otherwise
semiconductor elements may be broken.
Completely tighten terminal screws, otherwise malfunction, machine breakdown, or a fire may result.

4. Operation
!
Be sure to attach the case cover before turning the power on. Do
not remove the case cover during power supply, otherwise an electric shock may result.
Do not operate switches with wet hands, otherwise an electric
shock may result.
Do not touch the inverter terminal when power is being supplied to
the inverter although the machine is at rest, otherwise an electric
shock may result.
Trip resetting by turning the power on while the operation signal is
on will make the machine resume operation suddenly. Check that
the operation signal is off before turning the power on, otherwise
injury may result.
DANGER
CAUTION
!
Do not touch the die-cast case and radiation fan, which become
very hot, otherwise skin burn may result.
The inverter permits easy operation setting from low to high speed.
Carefully check the allowable range of the motor and machine
before setting, otherwise injury may result.
Prepare a retention brake separately as necessary, otherwise injury may result.
Do not check signals during operation, otherwise the equipment
may be broken.

5. Maintenance and inspection
!
This inverter has a high-voltage terminal, which is dangerous. Do
not touch it, otherwise an electric shock may result.
Conduct maintenance or inspection five minutes or more after the
input power is turned off, otherwise an electric shock may result.
Leave maintenance and inspection to a specialist. Remove accessories (watch, ring, etc.) before work, otherwise an electric shock
or injury may result.
!
Semiconductor elements are used in the inverter. Handle the
inverter carefully, otherwise static electricity, etc. may break the
inverter.
Do not change wiring or attach/detach the panel while the power is
supplied, otherwise an electric shock, injury, or equipment breakage may result.
DANGER
CAUTION
6. Others
Do not remodel the machine, otherwise an electric shock, injury,
or a fire may result.
