Safety Instructions
 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.

or less for the FR-F846-01800(75K) or higher.
Caution
Transportation and Mounting
 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.
 The ambient temperature must be between -10 and +40°C
(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 page 21 for details.)
 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 exceed 5.9 m/s2
 at 10 to 55 Hz in X, Y,
and Z directions. Otherwise the product 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.
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.
Otherwise you may get an electric shock.
 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 the inverter.
Trial run
 Before starting operation, each parameter must be
confirmed and adjusted. A failure to do so may cause some
machines to make unexpected motions.
Warning
Usage
 Stay away from the equipment when the retry function is set
as it will restart suddenly after a trip.
 Since pressing the STOP/RESET key may not stop output
depending on the function setting status, separate circuit
and switch that make an emergency stop (power OFF,
mechanical brake operation for emergency stop, etc.) must
be provided.
 Be sure to turn OFF the start (STF/STR) signal before
clearing the fault as this product will restart the motor
suddenly after a fault is cleared.
 Do not use a PM motor for an application where the PM
motor is driven by its load and runs at a speed higher than
the maximum motor speed.
 Use this inverter only with three-phase induction motors or
with a PM motor. Connection of any other electrical
equipment to the inverter output may damage the
equipment.
 Do not modify the equipment.
 Do not perform parts removal which is not instructed in this
manual. Doing so may lead to fault or damage of the
product.
