Additional Instructions
Also note the following points to prevent an accidental failure, injury, electric shock, etc.
Transportation and installation
When carrying products, use correct lifting gear to prevent injury.
Do not stack the inverter boxes higher than the number recommended.
Ensure that installation position and material can withstand the weight of the inverter. Install according to the information in the instruction
manual.
Do not install or operate the inverter if it is damaged or has parts missing. This can result in breakdowns.
When carrying the inverter, do not hold it by the front cover or setting dial; it may fall off or fail.
Do not stand or rest heavy objects on the product.
Check the inverter mounting orientation is correct.
Prevent other conductive bodies such as screws and metal fragments or other flammable substance such as oil from entering the
inverter.
As the inverter is a precision instrument, do not drop or subject it to impact.
Use the inverter under the following environmental conditions. Otherwise, the inverter may be damaged.
Operating condition
Ambient temperature
Ambient humidity
Storage temperature

Vibration
Temperature applicable for a short time, e.g. in transit.
2.9m/s² or less for the 04320 or more.
Wiring
Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not approved
from Mitsubishi.
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.
Test operation and adjustment
Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make unexpected
motions.
Operation
When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop.
Since pressing the
make an emergency stop (power off, mechanical brake operation for emergency stop, etc).
Make sure that the start signal is off before resetting the inverter alarm. A failure to do so may restart the motor suddenly.
The inverter can be started and stopped via the serial port communications link or the field bus. However, please note that depending
on the settings of the communications parameters it may not be possible to stop the system via these connections if there is an error
in the communications system or the data line. In configurations like this it is thus essential to install additional safety hardware that
makes it possible to stop the system in an emergency (e.g. controller inhibit via control signal, external motor contactor etc). Clear and
unambiguous warnings about this must be posted on site for the operating and service staff.
The load used should be a three-phase induction motor only. Connection of any other electrical equipment to the inverter output may
damage the inverter as well as 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 inverter.
