SAFETY INSTRUCTIONS
1. Electric Shock Prevention
A WARNING
-
A While power ison or when the inverter is running, do not open the front cover. You may get
an electric shock.
A Do not run the inverter with the front cover removed. Otherwise, you may access the
exposed highvoltage terminals and charging part and get an electric shock.
A If power is off, do not remove the front cover except for wiring or periodic inspection. You
may access the charged inverter circuits and get an electric shock.
A Before starting wiring or inspection, switch power off, wait for more than 10 minutes, and
check for no residual voltage with a tester or the like.
Use a class
3 or higher earthing method to earth the inverter.
A Any person who is involved in the wiring or inspection of this equipment should be fully
competent to do the work.
A Always install the inverter before wiring. Otherwise, you may get an electric shock or be
injured.
Operate the switches with dry hands to prevent an electric shock.
A Do not subject the cables to scratches, excessive stress, heavy loads or pinching.
Otherwise, you may get an electric shock.
2. Fire Prevention
a CAUTION
A Mount the inverter on an incombustible. Installing the inverter directly on or near a
combustible could lead to a fire.
A If the inverter has become faulty, switch power off on the inverter's power supply side. A
continuous flow of a large current could cause a fire.
A Do not connect the resistor directly to the DC terminals P, N. This could cause a fire .
3. Injury Prevention
A CAUTION
a Apply only the voltage specified inthe instruction manual to each terminal to prevent burst,
damage, etc.
a Ensure that the cables are connected to the correct terminals. Otherwise, burst, damage,
etc. may occur.
A Always make sure that polarity is correct to prevent burst, damage, etc.
A While power ison or for some time after power-off, do not touch the inverter as it ishot and
you may get burnt.

(2) Wiring
I 1
Im
Do not fit capacitive equipment such as power factor correction capacitor, noise filter or
surge suppressor to the output of the inverter.
A The connection orientation of the output cables U, V, W to the motor will affect the direction
of rotation of the motor.
(3) Trial run
h 1
A Check all parameter, and ensure that the machine will not be damaged by sudden start-up. I
(4) Operation
a CAUTION
A While the retry function is selected, keep away from the equipment because it will start
suddenly after an alarm stop.
A The stop key isvalid only when function setting has been made. Prepareanemergency stop
switch separately. A
- 3

A CAUTION
A Switch off the start signal when resetting the inverter. Failure to do so may start the motor
immediately after reset.
A The load used must be a three-phase induction motor. If any other electrical equipment is
connected to the inverter output, the equipment may be damaged.
A Do not modify the equipment.
a CAUTION
A The electronic motor thermal protection does not guarantee to prevent motor burn out.
A Do not use a contactor on the inverter input for frequent starting/stopping of the inverter.
use control signals.
To reducethe effect of mainsconductedelectromagnetic interference,usea RFInoisefilter.
Take care to ensure that electromagnetic radiation from the inverter does not damage or
affect the operation of nearby electrical equipment.
A Take adequate measures, e. g. install a reactor, to prevent power harmonics generated by
the inverter, which may cause the power capacitor and generator to overheat or burn.
A An inverter-driven 400V class motor should be insulation-enhanced. Surge voltages
attributable tothe wiring constant may occur at motor terminals, deteriorating the insulation
of the motor.
A When parameter clear or all parameter clear is performed, each parameter returns to the
factory setting. Re-setthe required parameters before starting operation.
A The inverter can be easily set for high-speed operation. Before changing its setting, fully
examine the performances of the motor and machine.
A The inverter does not have a holding stop facility. For emergency stop another circuit must
be used.
(5) Emergency stop
a CAUTION
A Provide a safety backup such as an emergency brake which will prevent the machine and
equipment from hazardous conditions if the inverter fails.
(6) Maintenance, inspection and parts replacement
h .
I A DOnot carry out a megger (insulation resistance) test on the control circuit of the inverter.
