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-MEGA 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-MEGA may not be used for a life-support system or other purposes directly related to the human safety.
• Though the FRENIC-MEGA 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 with a capacity of 50 HPor 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.

ii
• 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, 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.
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 of 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 multiconductor cable for the purpose of
running the leads 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, the insulation 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 may break down, which would expose the signal wire to the 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.

iii
• Before changing the switches or touching the control circuit terminal symbol plate, turn OFF the power and wait at least
five minutes forinverters of 40 HPor below, or at least ten minutes for inverters of 50 HPor 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. This may cause the malfunction of nearby sensors and devices. To
prevent 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 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.
• 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 Instruction Manual and the
FRENIC-MEGAUser's Manual, the motor may rotate with a torque or at a speed not permitted for the machine.
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 and L3/T, voltage may be output to inverter output terminals U, V, and W.
• Even if the run command is set to OFF, voltage is output to inverter output terminals U, V, and W if the servo-lock command
is ON.
• 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.

iv
• 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 oran 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.
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
of 40 HPor below, or at least ten minutes for inverters of 50 HPor 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.
• 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.

9. When you use an inverter at an altitude of more than 6600 ft (2000 m), you should apply basic insulation for the control
circuits of the inverter. The inverter cannot be used at altitudes of more than 9800 ft (3000 m).
10. The inverter has been tested with IEC61800-5-1 2007 5.2.3.6.3 Short-circuit Current Test under the following conditions.
Short-circuit current in the supply: 10 kA
Maximum 240 V for 200 V series with 40 HP or below
Maximum 230 V for 200 V series with 50 HP or above
Maximum 480 V for 400 V series
11. Connect the inverter to a power system which has a grounded neutral-point. In case of a non-grounded system (ex.
Delta-Delta), the control interface of the inverter is basic insulation, thus do not connect SELV circuit from external

Conformity with UL standards and CSA standards (cUL-listed for Canada)
UL/cUL-listed inverters are subject to the regulations set forth by the UL standards and CSAstandards (cUL-listed for Canada) by
installation within precautions listed below.
1. Solid state motor overload protection (motor protection by electronic thermal overload relay) is provided in each model.
Use function codes F10 to F12 to set the protection level.
2. Use Cu wire only.
3. Use Class 1 wire only for control circuits.
4. Short circuit rating
"Suitable For Use On A Circuit Of Delivering Not More Than 100,000 rms Symmetrical Amperes, 240 Volts Maximum for
230 V class input 40 HP or below, 230 Volts maximum for 230 V class input 50 HP or above when protected by Class J
Fuses or a Circuit Breaker having an interrupting rating not less than 100,000 rms Symmetrical Amperes, 240 Volts
Maximum." Models FRN; rated for 230 V class input.
"Suitable For Use On A Circuit Of Delivering Not More Than 100,000 rms Symmetrical Amperes, 480 Volts Maximum
when protected by Class J Fuses or a Circuit Breaker having an interrupting rating not less than 100,000 rms Symmetrical
Amperes, 480 Volts Maximum." Models FRN; rated for 460 V class input.
"Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit protection must be
provided in accordance with the National Electrical Code and any additional local codes."
5. Field wiring connections must be made by a UL Listed and CSA Certified closed-loop terminal connector sized for the wire
gauge involved. Connector must be fixed using the crimp tool specified by the connector manufacturer.
6. All circuits with terminals L1/R, L2/S, L3/T, R0, T0, R1, T1 must have a common disconnect and be connected to the same
pole of the disconnect if the terminals are connected to the power supply.
7. When using the inverter as a UL Enclosed Type (UL TYPE1), purchase Type 1 kit (option) and mount it on the inverter as
instructed.
