Thank you for choosing this Mitsubishi inverter plug-in option.

This Instruction Manual provides handling information and precautions for use of this product. Incorrect handling might cause an unexpected

fault. Before using this product, always read this Instruction Manual carefully to use this product correctly.

Please forward this Instruction Manual to the end user.

Safety instructions

Do not attempt to install, operate, maintain or inspect the 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

While the inverter power is ON, do not open the front cover or the wiring cover. Do not run the inverter with the front cover or the wiring cover removed. Otherwise

you may access the exposed high voltage terminals or the charging part of the circuitry and get an electric shock.

Do not remove the inverter front cover even if the power supply is disconnected. The only exception for this would be when performing wiring and periodic

inspection. You may accidentally touch the charged inverter circuits and get an electric shock.

Before wiring or inspection, LED indication of the inverter unit operation panel must be switched 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 is no residual voltage using a tester or the like. For some time after the

power-OFF, a high voltage remains in the smoothing capacitor, 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.

Caution

The voltage applied to each terminal must be the ones specified in the Instruction Manual. Otherwise a burst, damage, etc. may occur.

The cables must be connected to the correct terminals. Otherwise a burst, damage, etc. may occur.

The polarity (+ and -) must be correct. Otherwise a burst or damage may occur.

While power is ON or for some time after power OFF, do not touch the inverter as it will be extremely hot. Touching these devices may cause a burn.

Warning

Caution

Additional Instructions

The following instructions must be also followed. If the product is handled incorrectly, it may cause unexpected fault, an injury, or an electric

shock.

Caution

Transportation and mounting

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 substance such as oil.

If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.) infiltrate into a Mitsubishi product, the product will be damaged. Halogen-based materials are

often included in fumigant, which is used to sterilize or disinfest wooden packages. When packaging, prevent residual fumigant components from being infiltrated

into Mitsubishi products, or use an alternative sterilization or disinfection method (heat disinfection, etc.) for packaging. Sterilization of disinfection of wooden

package should also be performed before packaging the product.

Trial run

Before starting operation, each parameter must be confirmed and adjusted. A failure to do so may cause some machines to make unexpected motions.

Warning

Usage

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 product.

Caution

Usage

When parameter clear or all parameter clear is performed, the required parameters must be set again before starting operations. Because all parameters return to

their initial values.

Static electricity in your body must be discharged before you touch the product.

Maintenance, inspection and parts replacement

Do not carry out a megger (insulation resistance) test.

Disposal

The inverter must be treated as industrial waste.

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 Instruction Manual must be followed when operating the inverter.

2INSTALLATION

2.1 Pre-installation instructions

Check that the inverter's input power and the control circuit power are both OFF.

2.2 Installation procedure

Caution

With input power ON, do not install or remove the plug-in option. Otherwise, the inverter and plug-in option may be damaged.

To avoid damage due to static electricity, static electricity in your body must be discharged before you touch the product.

(1) Remove the inverter front cover. (Refer to Chapter 2 of

the Instruction Manual (Detailed) of the inverter for details

on how to remove the front cover.)

(2) For the two mounting holes (as shown in the next page)

that will not be tightened with mounting screws, insert

spacers.

(3) Fit the connector of the plug-in option to the guide of the

connector on the inverter unit side, and insert the plug-in

option as far as it goes.

(4) Fit the two locations, the left and right, of the plug-in

option securely to the inverter unit by screwing in the

supplied mounting screws. (tightening torque 0.33 N·m to

0.40 N·m) If the screw holes do not line up, the connector

may not be inserted deep enough. Check the connector.
