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
consequence according to conditions. Please follow the
instructions of both levels because they are important to
personnel safety.
WARNING
CAUTION
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 inverter power indicator lamp 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.

PRE-OPERATION INSTRUCTIONS
1.3 CC-Link Version
1.3.1 CC-Link Ver. 1.10
The conventional CC-Link products, whose inter-station cable lengths have equally been changed to 20cm
(7.87 inch) or more to improve the inter-station cable length restriction, are defined as CC-Link Ver. 1.10. In
comparison, the conventional products are defined as CC-Link Ver. 1.00.
Refer to the CC-Link Master Module Manual for the maximum overall cable lengths and inter-station cable
lengths of CC-Link Ver. 1.00 and Ver. 1.10.
1.3.2 CC-Link Ver. 2
The FR-A7NC is compatible with CC-
Link Ver.2.
When using the CC-Link Ver.2 setting
with the FR-A7NC, the master station
needs to be compatible with the CC-
Link Ver.2.
CC-Link Ver. 1.10 compatibility conditions
1)All modules that comprise a CC-Link system should be compatible with CC-Link Ver. 1.10.
2)All data link cables should be CC-Link Ver. 1.10 compatible, CC-Link dedicated cables.
(CC-Link Ver. 1.10 compatible cables have a logo or Ver. 1.10 indication.)
CAUTION
In a system that uses the CC-Link Ver. 1.00 and Ver. 1.10 modules and cables together, the maximum overall
cable length and inter-station cable length are as specified for CC-Link Ver. 1.00.
