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

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.

A-2

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.
