Warning
Caution
Caution
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".
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.
Electric shock prevention
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.
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 optio n 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 be fore 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.
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 inver ter.

example
Set the node address between "1 to 64" using node address switches on the FR-A8NF (refer to page 8).
The setting is applied at the next power-on.
Set the arrow ( ) of the corresponding switches to the number to set a desired node address.
• Setting example
Node address 1:
Set the arrow () of X10 (SW2) to "0" and the arrow
() of X1 (SW1) to "1".
NOTE
• Set the inverter node address before switching ON the inverter and do not change the setting while power is ON.
Otherwise you may get an electric shock.
• Set the node address switches so that the arrow points the exact position. If the switch is set between numbers,
normal data communication can not be established.
• If the node address switch is set to a value other than "1 to 64", it is invalid due to outside of setting range. In this case,
DEV LED of the option is lit red and E.OPT appears on the operation panel of the inverter.
• You cannot set the same node address to other devices on the network. (Doing so disables proper communication.)
• Changes in the node address setting are applied only at the next power-ON. Therefore, if the node address setting is
changed, make sure to power OFF and ON the inverter power.

4.2 Operation 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 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.

Running
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.
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.
