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.
1. Electric Shock Prevention
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".
Assumes that incorrect handling may
cause hazardous conditions, resulting
in death or severe injury.
Assumes that incorrect handling may
cause hazardous conditions, resulting
in medium or slight injury, or may
cause physical damage only.
Note that even the level may lead to a serious

CAUTION
SAFETY INSTRUCTIONS
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 high-
voltage terminals and charging part and get an electric shock.
•If power is OFF, do not remove the front cover except for
wiring or periodic inspection. You may access the charged
inverter circuits and get an electric shock.
•Before starting wiring or inspection, check to make sure that
the indication of the inverter operation panel is OFF, 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 the wiring or inspection of this
equipment should be fully competent to do the work.
•Always install the plug-in option before wiring. Otherwise,
you may get an electric shock or be injured.
•Do not touch the plug-in option 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. Additional Instructions
Also note the following points to prevent an accidental failure,
injury, electric shock, etc.
1) Transportation and mounting
2) Trial run
3) Usage
4) Maintenance, inspection and parts replacement
5) Disposal
6) General instruction
CAUTION
•Apply only the voltage specified in the instruction manual to
each terminal. Otherwise, burst, damage, etc. may occur.
•Ensure that the cables are connected to the correct terminals.
Otherwise, burst, damage, etc. may occur.
•Always make sure that polarity is correct to prevent damage, etc.
Otherwise, burst, damage may occur.
•While power is ON or for some time after power-OFF, do not
touch the inverter as it is hot and you may get burnt.
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.
•Check that the mounting orientation is correct.
•Prevent other conductive bodies such as screws and metal
fragments or other flammable substance such as oil from
entering the inverter.
CAUTION
•Before starting operation, confirm and adjust the parameters.
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,
reset the required parameters before starting operations.
Each parameter returns to the initial value.
•For prevention of damage due to static electricity, touch
nearby metal before touching this product to eliminate static
electricity from your body.
CAUTION
•Do not test the equipment with a megger (measure insulation
resistance).
CAUTION
•Treat as industrial waste.
All illustrations given in this manual may have been drawn with
covers or safety guards removed to provide in-depth
description. Before starting operation of the product, always
return the covers and guards into original positions as specified
and operate the equipment in accordance with the manual.

2.2 Installation procedure
1) Remove the inverter front cover.
2) Mount the hex-head screw for option
mounting into the inverter screw hole
(on earth plate). (size 5.5mm,
tightening torque 0.56N⋅m to 0.75N⋅m)
3) Securely fit the connector of the plug-in
option to the inverter connector along
the guides.
4) Securely fix the both right and left sides
of the plug-in option to the inverter with
the accessory mounting screws .
(Tightening torque 0.45N⋅m to
0.55N⋅m) If the screw holes do not line-
up, the connector may not have been
plugged securely. Check for loose
plugging.
REMARKS
• Remove a plug-in option after removing two screws on both left and right sides.
(When the plug-in option is mounted in the connector 3 (connector 1 for the FR-F700 series), it is easier to remove
the plug-in option after removing a control circuit terminal block.)

CAUTION
•Only one type of option per inverter may be used. When two or more options are mounted, priority is in the
order of inverter option connectors 1, 2 and 3. The options having lower priority are inoperative.
•When the inverter cannot recognize that the option is mounted due to improper
installation, etc., " to " (option fault) are displayed for the FR-
A700 series. The errors shown differ according to the mounting positions
(connectors 1, 2, 3).
••The FR-F700 series has one connection connector for the plug-in option. When
the inverter can not recognize that the option unit is mounted due to improper installation, etc., " "

2.3 Wiring
2.3.1 Wiring of FR-A7AX
Untwist the twisted pair shielded cables after stripping its sheath.
Also, perform protective treatment of the shield to ensure that it will not
make contact with the conductive area.
Strip off the sheath for the below length. If the length of the sheath peeled
is too long, a short circuit may occur with neighboring wires. If the length
is too short, wires might come off.
Wire the stripped cable after twisting it to prevent it from becoming loose.
(Do not solder it.)
Use a blade type terminal as required.

REMARKS
• Information on blade terminals
Commercially available product examples (as of March 2008)
Insert wires to a blade terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve.
Check the condition of the blade terminal after crimping. Do not use a blade terminal of which the crimping is
inappropriate, or the face is damaged.

2.3.2 Wiring at inverter side
For wiring of the inverter with one front cover, route wires between the control circuit terminal block
and front cover. If cables can not be routed between the control circuit terminal block and front cover
due to the increased number of cables, remove a hook of the front cover and use a space become
available.
For wiring of the inverter which has front cover 1 and 2, use the space on the left side of the control
circuit terminal block.
REMARKS
• When the hook of the inverter front cover is cut off for wiring, the protective structure (JEM1030) changes to open
type (IP00).
Cut off a hook on the inverter
front cover side surface.
(Cut off so that no portion is left.)

3.1 Pre-Installation Instructions
Make sure that the input power of the inverter is off.
3.2 Installation Procedure
The FR-E700 series has one connection connector for the plug-in option.
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.
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.
For wiring to terminal RUN, FU, SE of control circuit terminal, run
cables to prevent them from being caught between the option board
and control circuit terminal block as shown in the right figure. In case
cables are caught, the inverter may be damaged.
•When the inverter cannot recognize that the option is mounted due to
improper installation, etc., " " (option alarm) 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.
