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 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, switch power off, wait for more than 10 minutes, and check for no residual voltage
with a meter etc.
!Any person who is involved in the wiring or inspection of this equipment should be fully competent to do the work.
!Always install the option unit before wiring. Otherwise, you may get an electric shock or be injured.
!Operate the switches with dry hands to prevent an electric shock.
!Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise, you may get an electric
shock.
!While power is on, do not move the station number and baud rate setting switches. Doing so can cause an electric shock.
2. Injury Prevention
CAUTION
!Apply only the voltage specified in the instruction manual to each terminal to prevent damage, etc.
!Ensure that the cables are connected to the correct terminals. Otherwise, damage, etc. may occur.
!Always make sure that polarity is correct to prevent damage, etc.
!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 installation
CAUTION
!Do not install or operate the option unit 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 screws, metal fragments, conductive bodies or oil, other flammable substance from entering the inverter.
(2) Test operation and adjustment
CAUTION
!Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make
unexpected motions.
(3) Usage
WARNING
!Do not modify the equipment.

A - 4
CAUTION
!When parameter clear or all parameter clear is performed, each parameter returns to the factory setting. Re-set the
required parameters before starting operation.
!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
!Dispose of this product as general 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.
