for wiring or periodic inspection. You may accidentally touch the charged inverter circuits and get an electric shock.
Before wiring or inspection, power must be switched OFF.
To confirm that, LED indication of the operation panel must be checked. (It must be OFF.) Any person who is involved in wiring or inspection shall 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.
This product must be earthed (grounded). Earthing (grounding) must conform to the requirements of national and local safety regulations and electrical code (NEC section 250, IEC 61140 class 1 and other applicable standards). A neutral-point earthed (grounded) power supply for 400V class of this product in compliance with EN standard must be used.
Any person who is involved in wiring or inspection of this
product shall be fully competent to do the work.
This product body must be installed before wiring.
Otherwise you may get an electric shock or be injured.
Do not touch the setting dial or keys with wed hands. Doing
so may cause an electric shock.
Do not subject the cables to scratches, excessive stress,
heavy loads or pinching. Doing so may cause an electric shock.
Do not change the cooling fan while power is ON, as it is
dangerous.
Do not touch the printed circuit board or handle the cables
with wet hands. Doing so may cause an electric shock.
Never touch the motor terminals, etc. right after powering
OFF as the DC voltage is applied to the motor for 1 second at powering OFF if the main circuit capacitor capacity is measured. Doing so may cause an electric shock.

2. Fire Prevention
This product must be installed on a nonflammable wall
without holes (so that nobody touches the inverter heatsink on the rear side, etc.). Mounting it to or near flammable material can cause a fire.
If this product becomes faulty, the product power must be
switched OFF. A continuous flow of large current could cause a fire.
When using a brake resistor, a sequence that will turn OFF power when a fault signal is output must be configured. Otherwise the brake resi stor may overheat due to dam age of the brake transistor and possibly cause a fire.
Do not connect a resistor directly to the DC terminals P/+
and N/-. Doing so could cause a fire.
Be sure to perform daily and periodic inspections as specified in the Instruction Manual. If this product is used without inspection, an explosion, failure, or fire may occur.
3.Injury Prevention
The voltage applied to each terminal must be the ones
specified in the Instruction Manual. Otherwise an explosion or damage. may occur.
The cables must be connected to the correct terminals.
Otherwise an explosion or damage may occur.
Polarity must be correct. Otherwise an explosion or damage
may occur.

2 INSTALLATION AND WIRING

(Refer to page 43)
(Refer to page 6.)
(Refer to page 6.)
( Refer to the Instruction Manual (Applied))
Brake resistor (FR-ABR, MRS type, MYS type)
Braking capability can be improved. (0.4K or higher) Always install a thermal relay when using a brake resistor whose capacity is 11K or higher.
(Refer to page 18.)
AC power supply
Use within the permissible power supply specifications of the inverter. To ensure
AC reactor (FR-HAL)
safety, use a molded case circuit breaker, earth leakage circuit breaker or magnetic contactor to switch power ON/OFF.
Molded case circuit breaker (MCCB) or earth leakage circuit breaker (ELB), fuse
The breaker must be selected carefully since an in-rush current flows in the inverter at power on.
Magnetic contactor (MC)
Install the magnetic contactor to ensure safety. Do not use this magnetic contactor to start and stop the inverter. Doing so will cause the inverter life to be shortened.
Reactor (FR-HAL, FR-HEL option)
Reactors (option) must be used when power harmonics measures are taken, the power factor is to be improved or the inverter is installed near a large power supply system (500kVA or more). The inverter may be damaged if you do not use reactors. Select the reactor according to the model. Remove the jumpers across terminals P/+ and P1 to connect the DC reactor.

Devices connected to the output
Do not install a power factor correction capacitor, surge suppressor or noise filter (capacitor) on the output side of the inverter. When installing a molded case circuit breaker on the output side of the inverter, contact each manufacturer for selection of the molded case circuit breaker.
Earth (Ground)
To prevent an electric shock, always earth (ground) the motor and inverter. For reduction of induction noise from the power line of the inverter, it is recommended to wire the earth (ground) cable by returning it to the earth (ground) terminal of the inverter.
(FR-BSF01, FR-BLF)
Install a noise filter (ferrite core) to reduce the electromagnetic

NOTE
The life of the inverter is influenced by surrounding air temperature. The surrounding air temperature should be as
low as possible within the permissible range. This must be noted especially when the inverter is installed in an enclosure. (
Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully away from the main
circuit to protect them from noise. (Refer to page 8.)
Do not install a power factor correction capacitor, surge suppressor or noise filter (capacitor) on the inverter output
side. This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are connected, immediately remove them.
Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the inverter. In this case, install the FR-BIF optional noise filter (capacitor) (for use in the input side only) or FR-BSF01 or FR-BLF noise filter (ferrite core) to minimize interference.

When driving a 400V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor. Take the following measures 1) or 2) in this case.
1) Use a "400V class inverter-driven insulation-enhanced motor" and set frequency in Pr. 72 PWM frequency selection
2) Connect the surge voltage suppression filter (FR-ASF-H/FR-BMF-H) on the inverter output side.

NOTE
Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray
capacitances of the wiring, leading to a malfunction of the overcurrent protective function, fast response current limit
function, or stall prevention function or a malfunction or fault of the equipment connected on the inverter output side.
If malfunction of fast-response current limit function occurs, disable this function. If malfunction of stall prevention
function occurs, increase the stall level. ( Refer to Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention
operation selection in the chapter 4 of the Instruction Manual (applied))
When using the automatic restart after instantaneous power failure function with wiring length exceeding below,
select without frequency search (Pr. 162 = "1, 11"). (

(2) Wiring method
Wiring
Use a blade terminal and a wire with a sheath stripped off for the control circuit wiring. For a single wire, strip off the sheath of the wire and apply directly. Insert the blade terminal or the single wire into a socket of the terminal.
1) Strip off the sheath about the length below. If the length of the sheath peeled is too long, a short circuit may occur among neighboring wires. If the length is too short, wires might come off. Wire the stripped wire after twisting it to prevent it from becoming loose. In addition, do not solder it.
2) Crimp the blade terminal. Insert wires to a blade terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve. Check the condition of the blade terminal after crimping. Do not use a blade terminal of which the crimping is inappropriate, or the face is damaged.
