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.
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
WARNING
CAUTION
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.
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.
CAUTION

SAFETY INSTRUCTIONS

1. Electric Shock Prevention
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 high­voltage 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 indication of the inverter operation panel 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-1
2. Injury Prevention
3) Usage
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.
3. Additional Instructions
Also note the following points to prevent an accidental failure, injury, electric shock, etc.
1) Transportation and mounting
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.
2) Trial run
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.
4) Maintenance, inspection and parts replacement
CAUTION
• Do not test the equipment with a megger (measure insulation
resistance).
5) Disposal
CAUTION
• Treat as industrial waste.
6) General instruction
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.

• Set the node address switch to the switch number (alphabet) position correctly. If the switch is set between numbers, normal data communication can not be made.
• Do not set the node address to 7EH through FFH.
• Depending on the master module, 00H, 01H, 02H, 7CH, 7DH of node address may not be used.
• You cannot set the same node address to other devices on the network. (Doing so disables proper communication.)
• 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.

2 INSTALLATION

2.1 Pre-Installation Instructions

Make sure that the input power of the inverter is off.
CAUTION
With input power on, do not install or remove the plug-in option. Otherwise, the inverter and plug-in option may be damaged.
For prevention of damage due to static electricity, touch nearby metal before touching this product to eliminate static electricity from your body.

2.2 Installation Procedure

The FR-E700 series has one connection connector for the plug-in option.
CAUTION
• Always perform wiring to the main circuit terminals and control circuit terminals before installing the
option. Wiring cannot be performed after installing the option.
• When the inverter can not recognize that the option unit is mounted due to improper installation, etc.,
" " (option alarm) is displayed.
• Take care not to drop a mounting screw during mounting and removal.
• Pull out the option straight to remove. Otherwise, the connector may be damaged.

3.2 Wiring

Use the network connection cable which supports 12.0Mbps communication. (1) Strip off the sheath of the PROFIBUS communication dedicated cable and wind wires and shield cables
to use. If the length of the sheath pealed is too long, a short circuit may occur among neighboring wires. If the length is too short, cables and shield cables might come off.
Cable stripping size
Approx 5mm
Wire the stripped cable after twisting it to prevent it from becoming loose. (Do not solder it.) Use a bar type terminal as required.

CAUTION
When wiring, take care not to subject the cable to stress. After wiring, wire offcuts must not be left in the inverter. They may cause a fault, failure or
malfunction.

INVERTER SETTING

4.2 Operation Mode Setting

The inverter mounted with a communication option has three operation modes.
(1) PU operation [PU].............. Controls the inverter from the key of the operation panel on the inverter or
parameter unit (FR-PU07/FR-PA07).
(2) External operation [EXT] ...Controls the inverter by switching on/off external signals connected to the
control circuit terminals of the inverter. (The inverter is factory-set to this mode.)
(3) Network operation [NET] ... Controls the inverter with instructions from the network via the
communication option. (The operation signal and running frequency can be entered from the control circuit terminals depending on the Pr. 338 Communication operation
command source and Pr. 339 Communication speed command source setting. Refer to page 24.)

(1) Operation mode switching conditions
Before switching the operation mode, check that:
1) The inverter is at a stop;
2) Both the STF and STR signals are off; and
3) The Pr. 79 Operation mode selection setting is correct. (Set using the operation panel of the inverter or parameter unit (FR-PU07/FR-PA07).) Refer to the inverter manual for details of Pr. 79.
(2) Operation mode selection at power on and at restoration from instantaneous power failure
The operation mode at power on and at restoration from instantaneous power failure can be selected. Set a value other than "0" in Pr. 340 to select the network operation mode. After started in network operation mode, parameter write from the network is enabled.
REMARKS
• Change of the Pr. 340 setting is made valid when powering on or resetting the inverter.
• Pr. 340 can be changed with the operation panel independently of the operation mode.
