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".

SAFETY INSTRUCTIONS
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 high-
voltage 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
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.

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

2.2 Installation Procedure
1) Remove the inverter front cover.
2) Mount the hex-head screw for option
mounting into the inverter screw hole (on
earth plate). (size 5.5mm, tightening
torque 0.56N⋅m to 0.75N⋅m)
3) Securely fit the connector of the plug-in
option to the inverter connector along the
guides.
4) Securely fix the both right and left sides
of the plug-in option to the inverter with
the accessory mounting screws. If the
screw holes do not line-up, the connector
may not have been plugged snugly.
Check for loose plugging.
REMARKS
After removing two screws on the right and left places, remove the plug-in option.
(When the plug-in option is mounted in the connector 3, it is easier to remove the plug-in option after removing a
control circuit terminal block.)
