Safety instructions
Thank you for choosing this Mitsubishi Electric inverter control terminal option.
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.
Electric Shock Prevention
WARNING
Do not remove the front cover or the wiring cover while the power of the inverter is ON, and do not run the inverter with the front cover or the
wiring cover removed as the exposed high voltage terminals or the charging part of the circuitry can be touched. Doing so may cause an
electric shock.
Even if power is OFF, do not remove the front cover of the inverter except for wiring or periodic inspection as the inside of this product is
charged. Doing so may cause an electric shock.
Before wiring or inspection, check that the display of the inverter operation panel is OFF. Any person who is involved in wiring or inspection
shall wait for 10 minutes or longer after the power supply has been cut off, and check that there are no residual voltage using a tester or the
like.
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.
Do not attempt to install, operate, maintain or inspect the product until you have read through this Instruction Manual and supplementary
documents carefully to use the equipment correctly. Do not use this product until you have a full knowledge of the equipment, safety
carefully. 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".
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.
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.

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. Doing so may cause burns.
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 place 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 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.
Test operation
Before starting the test operation, confirm or adjust the parameter settings. Failure to do so may cause some machines to make unexpected
motions.
WARNING
Usage
Do not modify this 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.

3
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.
To avoid damage due to static electricity, static electricity in your body must be discharged before you touch this product.
Maintenance, inspection and parts replacement
Do not carry out a megger (insulation resistance) test.
Disposal
The product must be treated as industrial waste.
General instruction
For clarity, illustrations in this Instruction Manual may be drawn with covers or safety guards removed. Ensure all covers and safety guards
are properly installed prior to starting operation.
