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
specied covers and safety shields to the original position before
operation. Operate the inverter in conformity with the operation
manual.
The operation manual is subject to change for improvement of the
product, change in specications, and easy use of the manual itself.
The operation manual No. will be renewed when a revised edition
is issued.
Remodeling of the inverter by the customer is beyond the scope of
our warrantee, and we will not take responsibility for any result of
remodeling.
[ Safety Precautions ]
Carefully read this operation manual for correct use before installation,
operation, maintenance, and inspection. Thoroughly understand the
inverter, safety information, and precautions before use.
Safety precautions are classified into "DANGER" and "CAUTION" in this
manual.
: Improper handling entails danger,
possibly leading to death or serious
injury.
: Improper handling entails danger,
possibly leading to medium-degree or
slight injury or property damage.
Matters classified under CAUTION may also cause serious
results depending on the situation.
Be sure to strictly observe these safety precautions.
DANGER
CAUTION

- 2 -
(1) Conrmation 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 inverter to metal or other nonammables, otherwise a
re may break out.
Do not place the inverter near inammables, otherwise a re 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 re may break out.
Install the inverter on a floor strong enough to withstand the
weight of the inver ter according to the operation manual,
otherwise the inverter may drop, leading to injury.

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

(4) Operation
DANGER
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 o before turning the power on, otherwise
injury may result.
CAUTION
Do not touch the die-cast case and radiation fin, 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 -
(5) Maintenance and inspection
DANGER
This inverter has a high-voltage terminal, which is dangerous. Do
not touch it, otherwise an electric shock may result.
Conduct maintenance or inspection ve minutes or more after the
input power is turned o, 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.
CAUTION
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.
(6) Others
DANGER
Do not remodel the inverter, otherwise an electric shock, injury, or
a re may result.
