Thank you for choosing this Mitsubishi inverter option unit.
This Instruction Manual provides handling information and precautions for use of this product. Incorrect handling might cause an unexpected
fault. Before using this product, always read this Instruction Manual carefully to use this product correctly.
Please forward this Instruction Manual to the end user.
Electric shock prevention
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.
Safety instructions
Do not attempt to install, operate, maintain or inspect the product until you have read through this Instruction Manual and appended
documents carefully and can use the equipment correctly. Do not use this product until you have a full knowledge of the equipment, safety
information and instructions. In this Instruction Manual, the safety instruction levels are classified into "Warning" and "Caution".
Incorrect handling may cause hazardous conditions, resulting in death or severe injury.
Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material
damage.
The level may even lead to a serious consequence according to conditions. Both instruction levels must be followed
because these are important to personal safety.
Warning
While the inverter power is ON, do not open the front cover or the wiring cover. Do not run the inverter with the front cover or the wiring cover removed. Otherwise
you may access the exposed high voltage terminals or the charging part of the circuitry and get an electric shock.
Do not remove the inverter front cover even if the power supply is disconnected. The only exception for this would be when performing wiring and periodic
inspection. You may accidentally touch the charged inverter circuits and get an electric shock.
Before wiring or inspection, LED indication of the inverter unit operation panel must be switched OFF. Any person who is involved in wiring or inspection shall wait
for at least 10 minutes after the power supply has been switched OFF and check that there is no residual voltage using a tester or the like. For some time after the
power-OFF, a high voltage remains in the smoothing capacitor, and it is dangerous.
Any person who is involved in wiring or inspection of this equipment shall be fully competent to do the work.
Do not touch the operation panel or handle the cables with wet hands. Otherwise you may get an electric shock.
Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise you may get an electric shock.
Caution
Transportation and mounting
Do not install or operate the operation panel if it is damaged or has parts missing.
Do not stand or rest heavy objects on the product.
Warning
Caution
Caution

Caution
Transportation and mounting
The mounting orientation must be correct.
The surrounding air temperature must be between -10 to +50°C (non-freezing). Otherwise the inverter may be damaged.
The surrounding humidity must be 90%RH or less (non-condensing). Otherwise the inverter may be damaged.
The storage temperature (applicable for a short time, such as during transit) must be between -20 to +65°C. Otherwise the inverter may be damaged.
The inverter must be used indoors (without corrosive gas, flammable gas, oil mist, dust and dirt etc.) Otherwise the inverter may be damaged.
The inverter must be used at an altitude of 2500 m or less above sea level, with 5.9 m/s2or less vibration at 10 to 55 Hz (directions of X, Y, Z axes). Otherwise the
inverter may be damaged.
If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.) infiltrate into a Mitsubishi product, the product will be damaged. Halogen-based materials are
often included in fumigant, which is used to sterilize or disinfest wooden packages. When packaging, prevent residual fumigant components from being infiltrated
into Mitsubishi 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 packing the product.
Trial run
Before starting operation, each parameter must be confirmed and adjusted. A failure to do so may cause some machines to make unexpected motions.
Warning
Usage
Since pressing the STOP/RESET key of the operation panel may not stop output depending on the function setting status, separate circuit and switch that make an
emergency stop (power OFF, mechanical brake operation for emergency stop, etc.) must be provided.
OFF status of the start signal must be confirmed before resetting an inverter fault. Resetting an inverter fault with the start signal ON restarts the motor suddenly.
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 product.
Caution
Usage
When parameter clear or all parameter clear is performed, the required parameters must be set again before starting operations because all parameters return to
the initial value.
Static electricity in your body must be discharged before you touch the product.
Disposal
The inverter must be treated as industrial waste.
General instruction
Many of the diagrams and drawings in this Instruction Manual show the inverter without a cover or partially open for explanation. Never operate the inverter in this
manner. The cover must be reinstalled and the instructions in the Instruction Manual must be followed when operating the inverter.
