14 INSTALLATION
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 attached to the option connector with high priority can function at once if more than one option of the same
name are installed together on an inverter. Priority is given to option connectors in descending order (1 to 3), and options
having a lower priority do not function.
• When the inverter cannot recognize the option due to improper installation or any other 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 crimp 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 follows. 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 them.
Crimp the terminals on the wire.
Insert the wire into a crimp terminal, making sure that 0 to 0.5 mm of the wire protrudes from the end of the 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.
Wire strip length
CAUTION
• After wiring, wire offcuts must not be left in the inverter. They may cause a fault, failure or malfunction.

NOTE
• When using stranded wires without a 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 October 2020. 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.
