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.

Warning

			Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material
	Caution
			damage.
The	Caution			level may even lead to a serious consequence according to conditions. Both instruction levels must be followed

because these are important to personal safety.

 Electric shock prevention

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.

Injury prevention

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.

 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.

To avoid damage due to static electricity, 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 product 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.

4.2Operation mode setting

Powering ON the inverter with the communication option (FR-A8NF) installed starts the inverter in the Network operation mode. (The operation mode cannot be changed to the External operation mode when the FR-A8NF is installed.)

Operation mode switching conditions

Check the following before switching the operation mode.

• The inverter is at a stop.

• Both the STF and STR signals are turned OFF.

Operation mode switchover method

INVERTER SETTING		27

 Operation mode switching by the PU operation interlock signal (X12)

PU operation interlock is a function that forcefully changes the operation mode to the Network operation mode at turn-OFF of the X12 signal (Bit 11), which gives operation commands through the FL remote communication.

This function prevents the operation mode from being accidentally unswitched from the PU operation mode. If the operation mode left unswithced from the PU operation mode, the inverter does not reply to the commands sent through the FL remote communication.

X12		Function/operation

			Manual (Detailed) of the inverter.)
	Operation mode is forcibly switched to the Network.		Parameter write is disabled.
OFF	Network operation is enabled.
			(Note that the Pr.297 setting is available when Pr.296 ≠ "9999.")
	Switching to the PU operation mode is disabled.

The operation mode switches to the Network operation mode independently of whether the start signal (STF, STR) is ON or OFF. Therefore, the motor is run in the Network operation mode when the X12 signal is turned OFF with either of STF and STR ON.

At fault occurrence, pressing	of the operation panel resets the inverter.	4

NOTE

•If the X12 signal is ON, the operation mode cannot be switched to the PU operation mode when the start signal (STF, STR) is ON.

•The X12 signal is valid only when it is input via the FL remote communication. (The X12 signal is invalid when it is input from a control circuit terminal of the inverter.)

•When the FR-A8NF is installed, Pr.79 Operation mode selection and Pr.340 Communication startup mode selection settings are invalid.
