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.

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
(2) Loosen the terminal screw and insert the cable into the terminal.
Tighten each cable with fixing screws to the recommended tightening torque.
<Cable connection example>
Approx 5mm
Wire the stripped cable after twisting it to prevent it from
becoming loose.
In addition, do not solder it.
Use a bar type terminal as required.

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 (FR-DU07)
mounted on the inverter.
(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 21.)

INVERTER SETTING
4.2.2
(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 with the operation panel of the inverter.)
Refer to the inverter manual (applied) 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
1. Change of the Pr. 340 setting is made valid when powering on or resetting the inverter.
2. Pr. 340 can be changed with the operation panel independently of the operation mode.
