Mitsubishi Electric FR-F820-00046 Instruction Manual page 11

The following instructions must be also followed. If this product is handled incorrectly, it may cause unexpected fault, an injury,
or an electric shock.
CAUTION
Transportation and installation
 Any person who is opening a package using a sharp object, such as a knife or cutter, must wear gloves to prevent injuries
caused by the edge of the sharp object.
 This product must be transported in correct method that corresponds to the weight. Failure to do so may lead to injuries.
 Do not stand or place any heavy object on this product.
 Do not stack the boxes containing this product higher than the number recommended.
 When carrying this product, do not hold it by the front cover. Doing so may cause a fall or failure of the product.
 During installation, caution must be taken not to drop this product as doing so may cause injuries.
 This product must be installed on the surface that withstands the weight of the product.
 Do not install this product on a hot surface.
 The installing orientation of this product must be correct.
 This product must be installed on a strong surface securely with screws so that it does not drop.
 Do not install or operate this product if it is damaged or has parts missing.
 Foreign conductive objects must be prevented from entering this product. That includes screws and metal fragments or
other flammable substance such as oil.
 As this product is a precision instrument, do not drop or subject it to impact.
 The surrounding air temperature must be between -10 and +50°C (non-freezing) for this product at LD (light duty) rating
or between -10 and +40°C (non-freezing) for this product at SLD (super light duty) rating. Otherwise the product may be
damaged.
 The ambient humidity must be 95% RH or less (non-condensing) for this product. Otherwise the product may be
damaged. (Refer to
 The temporary storage temperature (applicable to a short limited time such as a transportation time) must be between -
20 and +65°C. Otherwise this product may be damaged.
 This product must be used indoors (without corrosive gas, flammable gas, oil mist, dust and dirt). Otherwise the product
may be damaged.
 This product must be used at an altitude of 2500 m or less, with 5.9 m/s
X, Y, Z axes). Otherwise the product may be damaged. (For the installation at an altitude above 1000 m, consider a 3%
reduction in the rated current per 500 m increase in altitude.)
 If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.), included in fumigants to sterilize or disinfect wooden
packages, infiltrate into this product, the product may be damaged. Prevent residual fumigant components from being
infiltrated into the product when packaging, or use an alternative sterilization or disinfection method (heat disinfection,
etc.). Note that sterilization or disinfection of wooden package 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.
Doing so may be overheated or burn out.
 The output of this product (output terminals U, V, W) must be correctly connected to a motor. Otherwise the motor rotates
inversely.
 Even after the power of this product is turned OFF, a PM motor is running for a while and the output terminals U, V, and
W of this product wired to the PM motor hold high voltages all that while. Before wiring other terminals, be sure that the
PM motor is stopped. Otherwise you may get an electric shock.
 Never connect a PM motor to the commercial power supply. Applying the commercial power to the input terminals (U,
V, W) on a PM motor will burn the PM motor. The PM motor must be applied a power from this product with the output
terminals (U, V, W).
Test operation
 Before starting the test operation, confirm or adjust the parameter settings. Failure to do so may cause some machines
to make unexpected motions.
