■Safety precautions
Read this manual thoroughly before proceeding with installation, connections (wiring), operation, or maintenance
and inspection. Ensure you have sound knowledge of the device and familiarize yourself with all safety
information and precautions before proceeding to operate the inverter.
Safety precautions are classified into the following two categories in this manual.
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.
Failure to heed the information contained under the CAUTION title can also result in serious consequences.
These safety precautions are of utmost importance and must be observed at all times.
Application
•The FRENIC-Ace is designed to drive a three-phase induction motor. Do not use it for single-phase motors or
for other purposes.
Fire or an accident could occur.
•The FRENIC-Ace may not be used for a life-support system or other purposes directly related to the human
safety.
•Though the FRENIC-Ace 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
•Install the inverter on a base made of metal or other non-flammable material.
Otherwise, a fire could occur.
•Do not place flammable object nearby.
Doing so could cause fire.
•Inverters FRN0085E2■-4or above, whose protective structure is IP00, involve a possibility that a human
body may touch the live conductors of the main circuit terminal block. Inverters to which an optional DC
reactor is connected also involve the same. Install such inverters in an inaccessible place.
Otherwise, electric shock or injuries could occur.
•Do not support the inverter by its front cover during transportation.
Doing so could cause a drop of the inverter and injuries.
•Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the
inverter or from accumulating on the heat sink.
•When changing the positions of the top and bottom mounting bases for external cooling, use only the
specified screws.
Otherwise, a fire or an accident might result.
•Do not install or operate an inverter that is damaged or lacking parts.
Doing so could cause fire, an accident or injuries.

xiv
Wiring
•If no zero-phase current (earth leakage current) detective device such as a ground-fault relay is installed in
the upstream power supply line, in order to avoid the entire power supply system's shutdown undesirable to
factory operation, install a residual-current-operated protective device (RCD)/earth leakage circuit breaker
(ELCB) individually to inverters to break the individual inverter power supply lines only.
Otherwise, a fire could occur.
•When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or
residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent
protection) in the path of each pair of power lines to inverters. Use the recommended devices within the
recommended current capacity.
•Use wires in the specified size.
•Tighten terminals with specified torque.
Otherwise, a fire could occur.
•When there is more than one combination of an inverter and motor, do not use a multicore cable for the
purpose of handling their wirings together.
•Do not connect a surge killer to the inverter's output (secondary) circuit.
Doing so could cause a fire.
•Be sure to connect an optional DC reactor (DCR) when the capacity of the power supply transformer exceeds
500 kVA and is 10 times or more the inverter rated capacity.
Otherwise, a fire could occur.
•Ground the inverter in compliance with the national or local electric code.
•Be sure to ground the inverter's grounding terminals G.
Otherwise, an electric shock or a fire could occur.
•Qualified electricians should carry out wiring.
•Be sure to perform wiring after turning the power OFF.
Otherwise, an electric shock could occur.
•Be sure to perform wiring after installing the inverter unit.
Otherwise, an electric shock or injuries could occur.
•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, a fire or an accident could occur.
•Do not connect the power supply wires to output terminals (U, V, and W).
•When connecting a DC braking resistor (DBR), never connect it to terminals other than terminals P(+) and
DB.
Doing so could cause fire or an accident.
•In general, sheaths of the control signal wires are not specifically designed to withstand a high voltage (i.e.,
reinforced insulation is not applied). Therefore, if a control signal wire comes into direct contact with a live
conductor of the main circuit, the insulation of the sheath might break down, which would expose the signal
wire to a high voltage of the main circuit. Make sure that the control signal wires will not come into contact
with live conductors of the main circuit.
Doing so could cause an accident or an electric shock.
•Before changing the switches or touching the control circuit terminal symbol plate, turn OFF the power and
wait at least five minutes for inverters FRN0115E2■-2

/ FRN0072E2■-4

/ FRN0011E2■-7

or below,
or at least ten minutes for inverters FRN0085E2■-4

or above. Make sure that the LED monitor and
charging lamp are turned OFF. Further, make sure, using a multimeter or a similar instrument, that the DC
link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC or below).
Otherwise, an electric shock could occur.
•The 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.

xv
Operation
•Be sure to mount the front cover before turning the power ON. Do not remove the cover when the inverter
power is ON.
Otherwise, an electric shock could occur.
•Do not operate switches with wet hands.
Doing so could cause electric shock.
•If the auto-reset function has been selected, the inverter may automatically restart and drive the motor
depending on the cause of tripping. Design the machinery or equipment so that human safety is ensured at
the time of restarting.
Otherwise, an accident could occur.
•If the stall prevention function (current limiter), automatic deceleration (anti-regenerative control), or overload
prevention control has been selected, the inverter may operate with acceleration/deceleration or frequency
different from the commanded ones. Design the machine so that safety is ensured even in such cases.
•The key on the keypad is effective only when the keypad operation is enabled with function code F02 (=
0, 2 or 3). When the keypad operation is disabled, prepare an emergency stop switch separately for safe
operations.
Switching the run command source from keypad (local) to external equipment (remote) by turning ON the
"Enable communications link" command LE disables the key. To enable the key for an emergency
stop, select the key priority with function code H96 (= 1 or 3).
•If any of the protective functions have been activated, first remove the cause. Then, after checking that the all
run commands are set to OFF, release the alarm. If the alarm is released while any run commands are set to
ON, the inverter may supply the power to the motor, running the motor.
Otherwise, an accident could occur.
•If you enable the "Restart mode after momentary power failure" (Function code F14 = 3 to 5), then the
inverter automatically restarts running the motor when the power is recovered.
Design the machinery or equipment so that human safety is ensured after restarting.
•If the user configures the function codes wrongly without completely understanding this User's Manual, the
motor may rotate with a torque or at a speed not permitted for the machine.
•Starting auto-tuning involves motor rotation. Sufficiently check that motor rotation brings no danger
beforehand.
An accident or injuries could occur.
•Even if the inverter has interrupted power to the motor, if the voltage is applied to the main circuit input
terminals L1/R, L2/S, L3/T, L1/L and L2/N, voltage may be output to inverter output terminals U, V, and W.
•Even if the motor is stopped due to DC braking or preliminary excitation, voltage is output to inverter output
terminals U, V, and W.
An electric shock may occur.
•The inverter can easily accept high-speed operation. When changing the speed setting, carefully check the
specifications of motors or equipment beforehand.
Otherwise, injuries could occur.
•Do not touch the heat sink and braking resistor because they become very hot.
Doing so could cause burns.
•The DC brake function of the inverter does not provide any holding mechanism.
Injuries could occur.
•Ensure safety before modifying the function code settings.
Run commands (e.g., "Run forward" FWD), stop commands (e.g., "Coast to a stop" BX), and frequency
change commands can be assigned to digital input terminals. Depending upon the assignment states of
those terminals, modifying the function code setting may cause a sudden motor start or an abrupt change in
speed.
•When the inverter is controlled with the digital input signals, switching run or frequency command sources
with the related terminal commands (e.g., SS1, SS2, SS4, SS8, Hz2/Hz1, Hz/PID, IVS, and LE) may cause a
sudden motor start or an abrupt change in speed.
•Ensure safety before modifying customizable logic related function code settings (U codes and related
function codes) or turning ON the "Cancel customizable logic" terminal command CLC. Depending upon the
settings, such modification or cancellation of the customizable logic may change the operation sequence to
cause a sudden motor start or an unexpected motor operation.
An accident or injuries could occur.

xvi
Maintenance and inspection, and parts replacement
•Before proceeding to the maintenance/inspection jobs, turn OFF the power and wait at least five minutes
for inverters FRN0115E2■-2

/ FRN0072E2■-4

/ FRN0011E2■-7

or below, or at least ten minutes
for inverters FRN0085E2■-4

or above. Make sure that the LED monitor and charging lamp are turned
OFF. Further, make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the
terminals P(+) and N(-) has dropped to the safe level (+25 VDC 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 carryout 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] 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.
•Never modify the inverter.
Doing so could cause an electric shock or injuries.
Disposal
•Treat the inverter as an industrial waste when disposing of it.
Otherwise injuries could occur.
