Injury Prevention
O Apply only the voltage specified in the instruction manual to each terminal. Otherwise, burst, damage, etc. may occur.
O Ensure that the cables are connected to the correct terminals. Otherwise, burst, damage, etc. may occur.
O Always make sure that polarity (+ and –) is correct to prevent damage, etc. Otherwise, burst, damage, etc. may occur.
O 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 a
burn.
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.
Transportation and installation
O Any person who is opening a package using a sharp object, such as a knife and cutter, must wear gloves to prevent injuries caused by the edge
of the sharp object.
O The product must be transported in correct method that corresponds to the weight. Failure to do so may lead to injuries.
O Do not stand or rest heavy objects on the product.
O Do not stack the inverter boxes higher than the number recommended.
O When carrying the inverter, do not hold it by the front cover or setting dial; it may fall off or fail.
O During installation, caution must be taken not to drop the inverter as doing so may cause injuries.
O Ensure that installation position and material can withstand the weight of the inverter. Install according to the information in the instruction
manual.
O Do not install the product on a hot surface.
O Check the inverter mounting orientation is correct.
O The inverter must be installed on a strong surface securely with screws so that it will not drop.
O Do not install or operate the inverter if it is damaged or has parts missing. This can result in breakdowns.
O Prevent other conductive bodies such as screws and metal fragments or other flammable substance such as oil from entering the inverter.
O As the inverter is a precision instrument, do not drop or subject it to impact.
O Use the inverter under the following environmental conditions. Otherwise, the inverter may be damaged.

*1
Temperature applicable for a short time, e.g. in transit.
*2
2.9 m/s² or less for the FR-A840-04320(160K)-R2R or higher.
O If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.) infiltrate into a Mitsubishi Electric product, the product will be damaged.
Halogen-based materials are often included in fumigant, which is used to sterilize or disinfect wooden packages. When packaging, prevent
residual fumigant components from being infiltrated into Mitsubishi Electric products, or use an alternative sterilization or disinfection
method (heat disinfection, etc.) for packaging. Sterilization of disinfection of wooden package should also be performed before packaging the
product.
O To prevent a failure, do not use the inverter with a part or material containing halogen flame retardant including bromine.
Wiring
O Do not install a power factor correction capacitor or surge suppressor/capacitor type filter on the inverter output side, which are not approved
from Mitsubishi Electric. These devices on the inverter output side may be overheated or burn out.
O The direction of rotation of the motor corresponds to the direction of rotation commands (STF/STR) only if the phase sequence (U, V, W) is
maintained.
