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".

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.

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.

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.

•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. Additional Instructions

Also the following points must be noted 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

•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.

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.

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.

•Static electricity in your body must be discharged before you

touch the product. Otherwise the product may be damaged.

CAUTION

•Do not test the equipment with a megger (measure insulation

resistance).

CAUTION

•This inverter plug-in option must be treated as industrial

waste.

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 Instruction manual of the inverter

must be followed when operating the inverter.
