Mitsubishi Electric FR-A820-00046 (0.4K) Instruction Manual page 13

CAUTION
Transportation and installing
 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.
 The 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 the product.
 Do not stack the boxes containing products higher than the number recommended.
 When carrying the 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 the inverter as doing so may cause injuries.
 The product must be installed on the surface that withstands the weight of the product.
 Do not install the product on a hot surface.
 The installing orientation of the inverter must be correct.
 The inverter must be installed on a strong surface securely with screws so that it does not drop.
 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 surrounding air temperature must be between -10 and +50°C
ND (normal duty) (initial setting), or LD (light duty) rating, and between -10 and +40°C
SLD (super light duty) rating. Otherwise the inverter may be damaged.
 The ambient humidity must be 95% RH or less (non-condensing) for the inverter. Otherwise the inverter 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 the inverter may be damaged.
 The inverter must be used indoors (without corrosive gas, flammable gas, oil mist, dust and dirt). Otherwise the inverter
may be damaged.
 The inverter must be used at an altitude of 2500 m or less, with 5.9 m/s
X, Y, Z axes). Otherwise the inverter may be damaged. (Refer to
 If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.), included in fumigants to sterilize or disinfect wooden
packages, infiltrate into the 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 of 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 inverter's output side. These
devices on the inverter output side may be overheated or burn out.
 The output of the inverter (output terminals U, V, W) must be correctly connected to a motor. Otherwise the motor rotates
inversely.
 Even after the inverter power is turned OFF, a PM motor is running for a while and the inverter's output terminals U, V,
and W wired to the PM motor hold high voltages all that while. To wire other terminals after the terminals U, V, and W
were wired, 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 the inverter with the output
terminals (U, V, W).
Test operation
 Before starting the test operation, confirm or adjust the parameter settings. A failure to do so may cause some machines
to make unexpected motions.
