Safety Instructions
Do not attempt to install, operate, maintain or inspect the
product until you have read through this Instruction Manual
and supplementary documents carefully and can use the
equipment correctly. Do not use this product until you have a
full knowledge of this product mechanism, safety information
and instructions.
Installation, operation, maintenance and inspection must be
performed by qualified personnel. Here, qualified personnel
means personnel who meets all the conditions below.
• A person who took a proper engineering training.
Such training may be available at your local Mitsubishi
Electric office. Contact your local sales office for schedules
and locations.
• A person who can access operating manuals for the
protective devices (e.g. light curtain) connected to the safety
control system. A person who has read and familiarized
himself/herself with the manuals.
In this Instruction Manual, the safety instruction levels are
classified into "WARNING" and "CAUTION"

follow the instructions of both levels as they are critical to
personal safety.
 Electric Shock Prevention
WARNING
 Do not remove the front cover or the wiring cover while the power of this
product is ON, and do not run this product with the front cover or the
wiring cover removed as the exposed high voltage terminals or the
charging part of the circuitry can be touched. Otherwise you may get an
electric shock.
 Even if power is OFF, do not remove the front cover except for wiring or
periodic inspection as the inside of this product is charged. Otherwise you
may get an electric shock.
 Before wiring or inspection, the power lamp must be switched 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).
 Any person who is involved in wiring or inspection of this product shall be
fully competent to do the work.
 The inverter 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.
 Before wiring or inspection for a PM motor, confirm that the PM motor is
stopped as a PM motor is a synchronous motor with high-performance
magnets embedded inside and high-voltage is generated at the motor
terminals while the motor is running even after the power of this product is
turned OFF. In an application, such as fan and blower, that the motor may
be driven by the load, connect a low-voltage manual contactor at this
product output side and keep it open during wiring and inspection of this
product. Otherwise you may get an electric shock.
 Fire Prevention
CAUTION
 Inverter must be installed on a nonflammable wall without holes in it so
that its components cannot be touched from behind. Installing it to or near
flammable material may cause a fire.
 If the inverter becomes faulty, the inverter power must be switched OFF. A
continuous flow of large current may 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 resistor
may excessively overheat due to damage of the brake transistor and
such, causing 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 (Detailed). There is a possibility of explosion, damage,
or fire if this product is used without inspection.

level may even lead to a
 Injury Prevention
CAUTION
 The voltage applied to each terminal must be the ones specified in the
Instruction Manual (Detailed). Otherwise an explosion or damage may
occur.
 The cables must be connected to the correct terminals. Otherwise an
explosion or damage may occur.
 The polarity (+ and -) must be correct. Otherwise an explosion or damage
may occur.
 While power is ON or for some time after power-OFF, do not touch the
inverter as it will be extremely hot. Touching these devices may cause
burns.
 Additional Instructions
The following instructions must be also followed. If the product
is handled incorrectly, it may cause unexpected fault, an injury,
or an electric shock.
CAUTION
Transportation and installation
 To prevent injury, wear cut-resistant gloves when opening packaging with
sharp tools.
 Use proper lifting techniques or a trolley when carrying products. Failure
to do so may lead to injuries.
 Do not stand or rest heavy objects on the product.
 Do not stack the boxes containing inverters higher than the number
recommended.
 When carrying the inverter, do not hold it by the front cover. It may fall or
break.
 During installation, caution must be taken not to drop the inverter as doing
so may cause injuries.
 The product must be installed on a surface that withstands the weight of
the inverter.
 Do not install the product on a hot surface.
 Ensure the mounting orientation of this product is correct.
 Ensure this product is mounted securely in its enclosure.
 Do not install or operate the inverter if it is damaged or has parts missing.
 Foreign conductive objects must be prevented from entering the inverter.
That includes screws and metal fragments or other flammable substance
such as oil.
 As the inverter is a precision instrument, do not drop or subject it to
impact.
 For the FR-A860-00090 or lower, the surrounding air temperature must be
-10 to +40°C for the LD, ND, or HD rating (-10 to +30°C for the SLD
rating) (non-freezing). Otherwise the inverter may be damaged.
 For the FR-A860-00170 to 01080, the surrounding air temperature must
be -10 to +40°C (non-freezing). Otherwise the inverter may be damaged.
 For the FR-A860-01440 or higher, the surrounding air temperature must
be -10 to +50°C for the LD or ND rating (-10 to +40°C for the SLD or HD
rating) (non-freezing). Otherwise the inverter may be damaged.
 The ambient humidity must be 95%RH or less (non-condensing).
Otherwise the inverter may be damaged. (Refer to
 The storage temperature (applicable for a short time, e.g. during transit)
must be between -20 and +65°C. Otherwise the inverter may be
damaged.
 The inverter must be used indoors (without corrosive gas, flammable gas,
oil mist, dust and dirt etc.) Otherwise the inverter may be damaged.
 Do not use this product at an altitude above 2500 m. Vibration should not
2
exceed 5.9 m/s at 10 to 55 Hz in X, Y, and Z directions. Otherwise the

inverter may be damaged. (For installation at an altitude above 1000 m,
consider a 3% reduction in the rated current per 500 m increase in
altitude.)
 If halogens (including fluorine, chlorine, bromine, and iodine) contained in
fumigants for wood packages enter this product, the product may be
damaged. Prevent the entry of fumigant residuals or use an alternative
method such as heat disinfection. Note that sterilization or disinfection of
wood packages should be performed before packing the product.
 To prevent a failure, do not use the inverter with a part or material
containing halogen flame retardant including bromine.
Wiring
 Do not install a power factor correction capacitor, surge absorber, or radio
noise filter on the output side of this product. These devices may overheat
or burn out.
 The output terminals (terminals U, V, and W) must be connected to a
motor correctly. Otherwise the motor will rotate inversely.
 Even with the power OFF, high voltage is still applied to the terminals U, V
and W while the PM motor is running. Ensure the PM motor has stopped
before carrying out any wiring.
 Never connect a PM motor to a commercial power supply.
Connecting a commercial power supply to the input terminals (U, V, W) of
a PM motor will burn it out. The PM motor must be connected with the
output terminals (U, V, W) of this product.
Test operation
 Before starting operation, each parameter must be confirmed and
adjusted. A failure to do so may cause some machines to make
unexpected motions.
