Safety instructions
Do not attempt to install, operate, maintain or inspect this product until you have read this Instruction Manual and appended documents
carefully. Do not use this product until you have a full knowledge of this product mechanism, 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.
Note that even the level may lead to a serious consequence depending on conditions. Be sure to follow the
instructions of both levels as they are critical to personnel safety.
WARNING
Do not remove the front cover or the wiring cover of the inverter while the inverter power is ON. Do not operate the inverter with any cover or wiring cover removed,
as accidental contact with exposed high-voltage terminals and internal components may occur, resulting in an electrical shock.
Even if power is OFF, do not remove the front cover of the inverter except for wiring or periodic inspection as you may accidentally touch the charged circuits and
get an electric shock.
Before wiring or inspection, check that the display of the inverter operation panel is OFF. Any person who is involved in wiring or inspection shall wait for 10 minutes
or longer after power 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 wiring or inspection of this product shall be fully competent to do the work.
This product must be installed before wiring. Otherwise you may get an electric shock or be injured.
Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Doing so may cause an electric shock.
Do not touch this product or handle the cables with wet hands. Doing so may cause an electric shock.
CAUTION
The voltage applied to each terminal must be as 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, damage, etc. may occur.
While power is ON or for some time after power OFF, do not touch the inverter as it will be extremely hot. Doing so may cause a burn.

product may be damaged. Prevent residual fumigant components from being infiltrated into the product when packaging, or use an alternative sterilization or
disinfection method (heat disinfection, etc.). Note that sterilization or disinfection of wooden package should also be performed before packing the product.
Test operation
Before starting operation, confirm or adjust the parameter settings. Failure to do so may cause some machines to make unexpected motions.
WARNING
Usage
Do not modify this product.
Do not remove any part which is not instructed to be removed in the Instruction Manuals. Doing so may lead to a failure or damage of this product.
CAUTION
Usage
As all parameters return to their initial values after Parameter clear or All parameter clear is performed, the needed parameters for operation of the inverter and this
product must be set again before the operation is started.
To avoid damage to this product due to static electricity, static electricity in your body must be discharged before you touch this product.
Maintenance, inspection and parts replacement
Do not carry out a megger (insulation resistance) test.
Disposal
This product must be treated as industrial waste.
General instruction
For clarity purpose, illustrations in this Instruction Manual may be drawn with covers or safety guards removed. Ensure all covers and safety guards are properly
installed prior to starting operation.

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
Do not install or remove this product while the inverter power is ON. Doing so may damage the inverter or this product.
To avoid damage due to static electricity, static electricity in your body must be discharged before you touch this product.
(1) Remove the inverter front cover. (Refer to Chapter 2 of
the Instruction Manual (Detailed) of the inverter for
instructions for removing the front cover.)
(2) Insert two spacers into the mounting holes that will not be
filled with mounting screws (see the diagrams on the next
page to identify the holes).
(3) Fit the board mounted option connector on this product to
the guide of the option connector on the inverter and
insert the plug-in option as far as it goes. (Select option
connector 1 or 2 on the inverter.)
(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.

10 INSTALLATION AND WIRING
NOTE
• When installing/removing the plug-in option, hold the sides of the option. Do not press on the parts on the option circuit
board. Stress applied to the parts by pressing, etc. may cause a failure.
• Be careful not to drop mounting screws during the installation or removal of the plug-in option.
• Only one option can be used. When multiple options are mounted, priority is given to option connectors 1, 2 and 3 on
the inverter in this order, and options having a lower priority do not function.
• When the inverter cannot recognize the option due to improper installation or any reason, the protective function (E.1
to E.3) is activated and the inverter cannot be operated. The indication shown (when a fault occurs) depends on the
connector used (option connector 1 to 3).
• When removing the plug-in option, remove the two screws on either side, and then pull it straight out. Pressure applied
to the option connector and to the option board may break the option.

2.3 Wiring
(1) For the wiring, strip off the sheath of a cable, and use it with a blade terminal. For single wire, the stripped wire can be used
without crimp terminal. Connect the end of wires (crimp terminal or stranded wire) to the terminal block.
Strip the signal wires as shown below. If too much of the wire is stripped, a short circuit may occur with neighboring wires. If not
enough of the wire is stripped, wires may become loose and fall out.
Twist the stripped end of wires to prevent them from fraying. Do not solder it.
Crimp the terminals on the wire.
Insert wires to the crimp terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve.
Check the condition of the crimp terminals after crimping. Do not use the crimp terminals of which the crimping is inappropriate,
or the face is damaged.

CAUTION
After wiring, wire offcuts must not be left in the inverter. They may cause a fault, failure or malfunction.

14 INSTALLATION AND WIRING
NOTE
• When using stranded wires without crimp terminal, twist enough to avoid short circuit with a nearby terminals or wires.
• Pulling out the wire forcefully without pushing the open/close button all the way down may damage the terminal block.
• Use a small flathead screwdriver (tip thickness: 0.4 mm/tip width: 2.5 mm). If a flathead screwdriver with a narrow tip
is used, terminal block may be damaged.
Commercially available products (as of February 2012. The product may be changed without notice.)
• Place the flathead screwdriver vertical to the open/close button. In case the blade tip slips, it may cause an inverter
damage or injury.
• When wiring cables to the inverter's RS-485 terminals while a plug-in option is mounted, take caution not to let the
cables touch the circuit board of the option or of the inverter. Otherwise, electromagnetic noises may cause
malfunctions.

Setting output signals
Use Pr.320 to Pr.322 to assign signals to the terminals ABC (1 to 3). The settings of Pr.320 to Pr.322 are the same as those of
Pr.190 to Pr.196 (output terminal function selection). For the details of Pr.190 to Pr.196, refer to the Instruction Manual
(Detailed) of the inverter.
NOTE
• All the outputs are shut off when the protective functions (E.1 to E.3) are activated.
• Negative logic cannot be set.
Adjusting the output terminal response level (Pr.418)
• The response level of the output terminals can be delayed in a range of 5 to 50 ms. (Operation example for the RUN signal.)
NOTE
• The response level is not adjusted while Pr.418 = "9999".
• When Pr.157 OL signal output timer is set for the Overload warning (OL) signal output, the OL signal is output when
the set time of (Pr.157 + Pr.418) elapses.
