3.1 Electric Shock Prevention
앫
While power is ON or when the inverter is running, do not open the front cover or wiring cover. Otherwise you may get an electric
앫
Do not run the inverter with the front cover removed. Otherwise you may access the exposed high-voltage terminals or the charging
part of the circuitry and get an electric shock.
앫
Even 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.
앫 Before starting wiring or inspection, check to make sure that the operation panel indicator is OFF, wait for at least 10 minutes
after the power supply has been switched off, and check that there are no residual voltage using a tester or the like. The capacitor
is charged with high voltage for some time after power OFF and it is dangerous.
앫 This inverter must be earthed (grounded). Earthing (Grounding) must conform to the requirements of national and local safety
regulations and electrical codes. (NEC section 250, IEC 536 class 1 and other applicable standards)
Use a neutral-point earthed (grounded) power supply for 400 V class inverter in compliance with EN standard.
앫 Any person who is involved in the wiring or inspection of this equipment should be fully competent to do the work.
앫 Always install the inverter before wiring. Otherwise you may get an electric shock or be injured.
앫 If your application requires by installation standards an RCD (residual current device) as up stream protection please select
according to DIN VDE 0100-530 as following:
Single phase inverter type A or B
Three phase inverter only type B
(Additional instructions on the use of a residual current device are contained on page 27.)
앫 Perform setting dial and key operations with dry hands to prevent an electric shock. Otherwise you may get an electric shock.
앫 Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise you may get an electric shock.

앫 Do not touch the printed circuit board or handle the cables with wet hands. You may get an electric shock.
앫 When measuring the main circuit capacitor capacity, the DC voltage is applied to the motor for 1 s at powering off. Never touch
the motor terminal, etc. right after powering off to prevent an electric shock.
shock.
3.2 Fire Prevention
앫 Install the inverter on a nonflammable wall without holes (so that nobody can touch the inverter heatsink on the rear side, etc.).
Mounting it to or near flammable material can cause a fire.
앫 If the inverter has become faulty, switch off the inverter power. A continuous flow of large current could cause a fire.
앫 When using a brake resistor, make up a sequence that will turn off power when an alarm signal is output. Otherwise, the brake
resistor may excessively overheat due to damage of the brake transistor and such, causing a fire.
앫 Do not connect a resistor directly to the DC terminals P/+, N/–. This could cause a fire and destroy the inverter. The surface
temperature of braking resistors can far exceed 100 °C for brief periods. Make sure that there is adequate protection against
accidental contact and a safe distance is maintained to other units and system parts.
3.3 Injury Prevention
앫 Apply only the voltage specified in the instruction manual to each terminal. Otherwise, burst, damage, etc. may occur.
앫 Ensure that the cables are connected to the correct terminals. Otherwise, burst, damage, etc. may occur.
앫 Always make sure that polarity is correct to prevent damage, etc. Otherwise, burst, damage, etc. may occur.

앫 The direction of rotation of the motor corresponds to the direction of rotation commands (STF/STR) only if the phase sequence
(U, V, W) is maintained.
4.3 Test Operation and Adjustment
앫
Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make unexpected motions.
4.4 Operation
앫 When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop.
앫 Since pressing key may not stop output depending on the function setting status, provide a circuit and switch separately
to make an emergency stop (power off, mechanical brake operation for emergency stop, etc).
앫 Make sure that the start signal is off before resetting the inverter alarm. A failure to do so may restart the motor suddenly.
앫 The inverter can be started and stopped via the serial port communications link or the field bus. However, please note that
depending on the settings of the communications parameters it may not be possible to stop the system via these connections
if there is an error in the communications system or the data line. In configurations like this it is thus essential to install
additional safety hardware that makes it possible to stop the system in an emergency (e.g. controller inhibit via control signal,
external motor contactor etc). Clear and unambiguous warnings about this must be posted on site for the operating and
service staff.
앫 The load used should be a three-phase induction motor only. Connection of any other electrical equipment to the inverter
output may damage the inverter as well as the equipment.
앫 Do not modify the equipment.
앫 Do not perform parts removal which is not instructed in this manual. Doing so may lead to fault or damage of the inverter.

CAUTION
CAUTION
CAUTION
CAUTION
The electronic thermal relay function does not guarantee protection of the motor from overheating. It is recommended to install
both an external thermal and PTC thermistor for overheat protection.
앫 Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter. Otherwise, the life of the
inverter decreases.
앫 Use a noise filter to reduce the effect of electromagnetic interference and follow the accepted EMC procedures for proper
installation of frequency inverters. Otherwise nearby electronic equipment may be affected.
앫 Take appropriate measures regarding harmonics. Otherwise this can endanger compensation systems or overload generators.
앫 When a 400 V class motor is inverter-driven, please use an insulation-enhanced motor or measures taken to suppress surge
voltages. Surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of
the motor.
앫 When parameter clear or all clear is performed, set again the required parameters before starting operations. Each parameter
returns to the initial value.
앫
The inverter can be easily set for high-speed operation. Before changing its setting, fully examine the performances of the motor
and machine.
앫
The DC braking function of the frequency inverter is not designed to continuously hold a load. Use an electro-mechanical holding
brake on the motor for this purpose.
앫 Before running an inverter which had been stored for a long period, always perform inspection and test operation.
For prevention of damage due to static electricity, touch nearby metal before touching this product to eliminate static electricity
앫
from your body.
앫 If you are installing the inverter to drive a three-phase device while you are contracted for lighting and power service, consult
your electric power supplier.
4.5 Emergency Stop
앫
Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions
if the inverter fails.
앫
When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), damage to internal parts of the inverter,
etc. Identify the cause of the trip, then remove the cause and power on the breaker.
앫
When the protective function is activated (i. e. the frequency inverter switches off with an error message), take the corresponding
corrective action as described in the inverter manual, then reset the inverter, and resume operation.
4.6 Maintenance, Inspection and Parts Replacement
앫 Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. It will cause a failure.
It is recommended to make the following checks periodically:
앫 Check for loose screws in the terminal block. Retighten any loose screws.
앫 Check for dust accumulation on the inverter. Clean the heat sink and the cooling fan of the inverter.
앫 Check for unusual noise generated by the inverter. Retighten installation screw.
앫 Check for the operation condition. Keep the operation condition of inverter as written in the manual.
4.7 Disposal of the Inverter

CAUTION
앫 To prevent a malfunction due to noise, keep the signal cables more than 10 cm away from the power cables. Also separate the main circuit wire
of the input side and the output side.
앫 After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in a control box etc., take
care not to allow chips and other foreign matter to enter the inverter.
앫 Set the voltage/current input switch in the correct position. An incorrect setting may cause a fault, failure or malfunction.
앫 The output of the single-phase power input specification is three-phase 230 V.
4.2 Main Circuit Terminal Specifications
4.2.1 Terminal Arrangement of the Main Circuit Terminal, Power Supply and the Motor Wiring
Single-Phase 200 V Class
FR-D720S-008SC to 042SC FR-D720S-070SC and 100SC
Three-Phase 400 V Class
FR-D740-012SC to 080SC FR-D740-120SC, 160SC
CAUTION
앫 Make sure the power cables are connected to the R/L1, S/L2, T/L3 (three-phase 400 V class) resp. to the L1, N (for single-phase
200 V class). Never connect the power cable to the U, V, W of the inverter. Doing so will damaged the inverter. (Phase sequence
needs not to be matched.)
앫 Connect the motor to U, V, W. At this time turning on the forward rotation switch (signal) rotates the motor in the clockwise
direction when viewed on the motor shaft.
