4 Additional Instructions
Also note the following points to prevent an accidental failure, injury, electric shock, etc.
4.1 Transportation and Installation
Transport the product using the correct method that corresponds to the weight. Failure to observe this could lead to injuries.
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.
Ambient temperature
Ambient humidity
Storage temperature
Atmosphere
Altitude
Vibration
Temperature applicable for a short time, e.g. in transit.
4.2 Wiring
Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not
approved from Mitsubishi Electric.
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.
4.3 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.
4.4 Operation
When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop.
Since pressing key may not stop output depending on the function setting status, provide a circuit and switch separately
to 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.
–10 °C to +50 °C (non-freezing)
90 % RH or less (non-condensing)
–20 °C to +65 °C
Indoors (free from corrosive gas, flammable gas, oil mist, dust and dirt)
Maximum 1000m above sea level for standard operation. After that derate by 3 % for every extra 500 m up to
2500 m (91 %)
5.9 m/s² or less at 10 to 55 Hz (directions of X, Y, Z axes)
