ii

iii
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.
• 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 there isn’t zero-phase current (Earth leakage current) detective device, such as a ground-fault relay
in the upstream power supply line, which is to avoid undesirable system shutdown. Install a
residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) individually to
break the individual inverter’s power supply line.
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 running 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 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.

iv
• 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 the inverter output terminals (U, V, and W).
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, turn OFF the power and wait at least 10 minutes. Make sure that the
charging lamp is 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.
• The leakage current of FRENIC-Lift is comparatively large for the EMC filter built-in type of inverters.
Be sure to perform protective grounding.
Otherwise, an accident or an electric shock 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 any of the protective functions have been activated, first remove the cause. Then, after checking that
all the 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.

v
• If the user configures the function codes wrong without completely understanding this Instruction
Manual and the FRENIC-Lift LM2A series Reference 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 motor is stopped due to DC braking, 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 because it becomes 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 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.
• If any abnormality is found in the inverter or motor, immediately stop it and perform troubleshooting,
referring to the FRENIC-Lift LM2A series Reference Manual.
An accident or injuries could occur.

vi
Maintenance and inspection, and parts replacement
• Before proceeding to maintenance or inspection, turn OFF the power and wait at least 10 minutes.
Make sure that the charging lamp is 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 this 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
