Safety instructions
Thank you for choosing this Mitsubishi Electric inverter plug-in option.
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
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 product shall be fully competent to do the work.
The plug-in option must be installed before wiring. Otherwise you may get an electric shock or be injured.
Do not touch the plug-in option 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.
WARNING 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.
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 this product mechanism,
safety information and instructions. In this Instruction Manual, the safety instruction levels are classified into "WARNING" and "CAUTION".
CAUTION
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.

Injury 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.
CAUTION
The voltage applied to each terminal must be as specified in the Instruction Manual. Otherwise an explosion or damage may occur.
The cables must be connected to the correct terminals. Otherwise an explosion or damage may occur.
The polarity (+ and -) must be correct. Otherwise an explosion 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. Touching these devices may cause
burns.
CAUTION
Transportation and installation
Do not install or operate the plug-in option if it is damaged or has parts missing.
Do not stand or rest heavy objects on the product.
Ensure the mounting orientation of this product is 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 halogens (including fluorine, chlorine, bromine, and iodine) contained in fumigants for wood packages enter this product, the product may
be damaged. Prevent the entry of fumigant residuals or use an alternative method such as heat disinfection. Note that sterilization or
disinfection of wood packages should be performed before packing the product.
Trial run
Before starting operation, confirm or adjust the parameter settings. Failure to do so may cause some machines to make unexpected
motions.
WARNING
Usage
Do not modify the product.
Do not remove any part which is not instructed to be removed in the Instruction Manuals. Doing so may lead to a failure 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 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.
