Safety Precautions
Read the safety precautions thoroughly for safe use of
the product and become familiar with correct use before
handling the product.
Safety precautions are classified into the following four
categories in this manual: WARNING, CAUTION and
NOTE.
Failure to heed the information indicated by this
symbol may lead to dangerous conditions,
possibly resulting in death or serious bodily
injuries.
Failure to heed the information indicated by this
symbol may lead to dangerous conditions,
possibly resulting in minor or light bodily
injuries and/or substantial property damage.
NOTE Offers important information for your under-
standing and handling of the product.
WARNING and CAUTION are given in Safety
Precautions and the section where injury or damage is
anticipated. NOTE is given only in the section that
requires additional information.
Failure to heed the information, even though its symbol
is , may cause serious results depending
on the situation. Since all WARNING and CAUTION
contain important factors, always observe their
precautions.
The converter system is used to drive machinery in
various places, so it is impossible to anticipate all the
situations where troubles will be caused by potential
factors. Therefore, observe also the safety precautions
needed for inverters, motors, equipment, and the places
of use.
Remarks:
- Serious bodily injuries include loss of eyesight,
injury, burn (hot or cold), electric shock, fracture of a
bone, poisoning or the like. All of these cause
aftereffect and require hospitalization or attendance
at the hospital for a long term for cure.
- Minor and medium injuries indicate burns and
electric shock that does not require hospitalization or
long-term visiting care.
- Damage to the property means enlargement loss
concerning breakage of property and damage to the
equipment.
• Peripheral devices such as the filter stack, filtering resistors and reactors, and boosting reactors as well as the
heat sink become hot. NEVER touch these devices while the power is ON and immediately after the power is
turned OFF until they cool down.
Burns and injuries may result.
• Mount the fro
nt cover or the like without fail on the peripheral devices to keep them away from the reach of
people.
Electric shock or injury may result.

Application
• The PWM converter is intended for use in combination with a Fuji inverter that drives a three-phase induction
motor, and must not be used for any other purposes.
Fire could result.
• The PWM converter may not be used for a life-support system or other purposes directly related to the human
safety.
•
Though the product is manufactured under strict quality control, install safety devices for applications where
serious accidents or property damages are foreseen in relation to the failure of it.
An accident could occur.
Installation
• Mount the converter on a base made of metal or other non-flammable material.
Otherwise, a fire could occur.
• Do not place flammable material nearby.
Doing so could cause fire.
• Install the converter in an inaccessible place, e.g., in a control panel.
Otherwise, electric shock or injuries could occur.
• Do not support the converter by its front cover during transportation.
Doing so could cause a drop of the converter and injuries.
•
Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the
converter or from accumulating on the heat sink.
Otherwise, a fire or an accident might result.
• Do not install or run a converter that is damaged or lacking parts.
Doing so could cause injuries.
• When changing the positions of the mounting bases, use the attached screws.
Otherwise, injuries could occur.
iii

Wiring
•
When wiring the converter to the power source, insert a recommended molded case circuit breaker (MCCB) or
residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) in the path of each pair
of power lines to the converter.
Otherwise, a fire could occur.
• Use the peripheral devices authorized by Fuji Electric for the converter.
Otherwise, a fire or bodily injuries could occur.
• Use wires in the specified size.
Otherwise, a fire could occur.
• Be sure to ground the converter's grounding terminals.
Otherwise, electric shock or fire could occur.
• Qualified electricians should carry out wiring.
Otherwise, an electric shock could occur.
• Ensure that the power is turned OFF (open circuit) before starting wiring.
Otherwise, an electric shock could occur.
• Be sure to complete installation of the converter before wiring.
Otherwise, an electric shock or injuries could occur.
• Never supply power to a converter whose parts are broken o
r coming off, or to a converter damaged in
transportation.
Doing so could cause an electric shock or fire.
• Never connect a DC reactor to the converter.
Doing so could cause a fire.
• Ensure that the number of input phases and the rated voltage of the product match the number of phases and the
voltage of the AC power supply to which the product is to be connected.
Otherwise, injuries could occur.
• Ensure that the polarity of the converter’s DC terminals (P(+) and N(-)) match that of the inverter’s ones.
Otherwise, an accident could occur.
• The converter, filter stack, inverter, motor and wiring generate electric noise. Be careful about malfunction of
the nearby sensors and devices. To prevent them from malfunctioning, implement noise control measures.
Otherwise, an accident could occur.
Operation
•
Be sure to mount the front cover before turning the power ON. Do not remove the cover when the converter
power is ON.
An electric shock could occur.
• Do not operate switches with wet hands.
Doing so could cause electric shock.
•
Confirm that the Run signal is OFF before resetting an alarm. Resetting an alarm with the Run signal being ON
may cause a sudden motor start.
An accident could occur.
• Never touch the terminals when the power is supplied to the converter, filter stack or peripheral devices even if
the converter is stopped.
An electric shock could occur.
iv

• Do not touch the heat sink, filtering resistors, filtering reactors or boosting reactors because they become hot.
Burns may result.
Maintenance and inspection, and parts replacement
•
Before proceeding to the maintenance/inspection, turn the power OFF, make sure that the charging lamp is
turned OFF. Further, make sure that the DC voltage across the terminals P(+) and N(-) and the terminal voltage
of the filtering capacitor is +25VDC or below.
Otherwise, an electric shock could occur.
• Always carry out the daily and periodic inspections described in the instruction/
user's manual. Use of the
inverter for long periods of time
without carrying out regular inspections could result in malfunction or
damage, and an accident or fire could occur.
• It is recommended that periodic inspections be carried
out every one to two years, however, they should be
carried out more frequently depending on the usage conditions.
•
It is recommended that parts for periodic replacement be replaced in accordance with the standard replacement
frequency indicated in the user's manual. Use of the product for long periods of time without replacement could
result in malfunction or damage, and an accident or fire could occur.
• Contact outputs [30A/B/C] and [Y5A/C] and [73A/C]
use relays, and may remain ON, OFF, or undetermined
when their lifetime is reached. In the interests of safety, equip the inverter with an external protective function.
Otherwise, an accident or fire could occur.
• Maintenance, inspection, and parts replacement should be made only by qualified persons.
• Take off the watch, rings and other metallic objects before starting work.
• Use insulated tools.
Otherwise, an electric shock or injuries could occur.
Disposal
• Treat the product as an industrial waste when disposing of it.
Otherwise, injuries could occur.
Others
• Never attempt to modify the product.
Doing so could cause an electric shock or injuries.
