WARNING
CAUTION
CAUTION
This Instruction Manual provides handling information and precautions for use of the equipment. 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.
Safety instructions
Do not attempt to install, operate, maintain or inspect the product until you have read through this Instruction Manual and supplementary
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".
Note that even the level may lead to a serious consequence depending on conditions. Be sure to follow the
instructions of both levels as they are critical to personnel safety.
Electric Shock Prevention
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.
WARNING
Do not remove the front cover or the wiring cover while the inverter power is ON. Do not operate the inverter with any cover or wiring cover removed, as accidental
contact with exposed high-voltage terminals and internal components may occur, resulting in an electrical shock.
Even if power is OFF, do not remove the front cover except for wiring or periodic inspection as 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 10 minutes or longer after power OFF and check that there are no residual voltage using a tester or the like. The capacitor is charged with high voltage for some
time after power OFF, and it is dangerous.
Any person who is involved in wiring or inspection of this equipment shall be fully competent to do the work.
The control terminal option must be installed before wiring. Otherwise you may get an electric shock or be injured.
Do not touch the control terminal option or handle the cables with wet hands. Doing so may cause an electric shock.
Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Doing so may cause an electric shock.
Injury Prevention
CAUTION
The voltage applied to each terminal must be the ones specified in the Instruction Manual. Otherwise a burst, damage, etc. may occur.
The cables must be connected to the correct terminals. Otherwise a burst, damage, etc. may occur.
The polarity (+ and -) must be correct. Otherwise a burst or damage may occur.
While power is ON or for some time after power OFF, do not touch the inverter as it will be extremely hot. Doing so 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.
CAUTION
Transportation and installation
Do not install or operate the control terminal option if it is damaged or has parts missing.
Do not stand or rest heavy objects on the product.
The mounting orientation must be correct.
Foreign conductive objects must be prevented from entering the inverter. That includes screws and metal fragments or other flammable substance such as oil.
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 a product.
Test operation
Before starting operation, each parameter must be confirmed and adjusted. Failure to do so may cause some machines to make unexpected motions.
WARNING
Usage
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
As all parameters return to their initial values after the Parameter clear or All parameter clear is performed, the parameters must be set again as required before the
operation is started.
Static electricity in your body must be discharged before you touch the product.
Maintenance, inspection and parts replacement
Do not carry out a megger (insulation resistance) test.
Disposal
The product must be treated as industrial waste.
For clarity purpose, illustrations in this Instruction Manual may be drawn with covers or safety guards removed. Ensure all covers and safety guards are properly
General instruction
installed prior to starting operation.
