Thank you for choosing this Mitsubishi Inverter plug-in option.
This Instruction Manual gives handling information and
precautions for use of this equipment. Incorrect handling might
cause an unexpected fault. Before using the equipment, please
read this manual carefully to use the equipment to its optimum.
Please forward this manual to the end user.
This section is specifically about
safety matters
Do not attempt to install, operate, maintain or inspect this
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
WARNING
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.
CAUTION
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.
SAFETY INSTRUCTIONS
1. Electric Shock Prevention
WARNING
• While power is ON or when the inverter is running, do not
open the front cover. You may get an electric shock.
• Do not run the inverter with the front cover or wiring cover
removed. Otherwise, you may access the exposed highvoltage terminals and charging part and get an electric shock.
• Even if power is OFF, do not remove the front cover except for
wiring or periodic inspection. You may accidentally touch the
charged inverter circuits and get an electric shock.
• Before wiring or inspection, power must be switched OFF. To
confirm that, LED indication of the operation panel must be
checked. (It must be 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
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 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.

2. Injury Prevention
3) Usage
CAUTION
• The voltage applied to each terminal must be the ones
specified in the Instruction Manual. Otherwise burst, damage,
etc. may occur.
• The cables must be connected to the correct terminals.
Otherwise burst, damage, etc. may occur.
• Polarity must be correct. Otherwise burst, damage, etc. may
occur.
• While power is ON or for some time after power-OFF, do not
touch the inverter as they will be extremely hot. Doing so can
cause burns.
3. Additional Instructions
Also the following points must be noted to prevent an accidental
failure, injury, electric shock, etc.
1) Transportation and mounting
CAUTION
• 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.
• 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 substances such as oil.
2) Trial run
CAUTION
• Before starting operation, each parameter must be confirmed
and adjusted. A failure to do so may cause some machines to
make unexpected motions.
WARNING
• 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.
CAUTION
•
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.
• For prevention of damage due to static electricity, nearby
metal must be touched before touching this product to
eliminate static electricity from your body.
4) Maintenance, inspection and parts replacement
CAUTION
• Do not test the equipment with a megger (measure insulation
resistance).
5) Disposal
CAUTION
• This inverter plug-in option must be treated as industrial
waste.
6) 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 inverter
manual must be followed when operating the inverter.

INSTALLATION AND WIRING
2.1 Pre-Installation Instructions
Make sure that the input power of the inverter is off.
CAUTION
With input power on, do not install or remove the plug-in option. Otherwise, the inverter and
plug-in option may be damaged.
For prevention of damage due to static electricity, touch nearby metal before touching this
product to eliminate static electricity from your body.
2.2 Installation Procedure
CAUTION
• Always perform wiring to the main circuit terminals and control circuit terminals before installing the
option. Wiring cannot be performed after installing the option.
• When mounting the plug-in option, do not let wires get caught in the plug-in option or the spacer for option
mounting. If a wire gets caught, the inverter and the plug-in option may be damaged.
• When the inverter cannot recognize that the option is mounted due to improper installation, etc., " "
(option fault) is displayed.
• Take care not to drop a mounting screws during mounting and removal.
• Pull out the option straight to remove. Otherwise, the connector may be damaged.
REMARKS
• Bcause the voltage class, model name and serial number (only voltage class is labeled for FR-E720-5.5KSC (FR-
E720-240SC), FR-E740-5.5KSC (FR-E740-120SC) or higher) are written on the PU cover, replace the PU cover of
the plug-in option with the removed PU cover of the inverter.
