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
!
Do not modify the equipment.
WARNING
A - 3
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.

INSTALLATION
(1) Remove the front cover and option wiring port cover. (Refer to the inverter manual.)
(2) Remove the sponge from the inboard option connector, align the option unit connector with the inboard option connector
of the inverter, and securely insert it far enough into the inverter.
(3) Securely fix the top and bottom of the option unit to the inverter with the accessory mounting screws. If the screw holes do
not match, check for insecure connector insertion. The connector may not have been inserted securely.
(4) Reinstall the front cover to the inverter. (Refer to the inverter manual.)
Note:1. While the inboard option is plugged in, store the option wiring port cover carefully.
2. When this option is plugged in, the protective structure of the inverter is the open type (IP00).
3. If the inverter cannot recognize the plugged-in option, the E.OPT error appears. (Refer to the inverter manual.)

(4) When the CPU has automatic refresh function (example: QnA series CPU)
Through communication with the corresponding devices using sequence ladder logic, data is automatically transferred to
the refresh buffer of the master station at the execution of the END instruction to perform communication with the remote
devices.
(5) When the CPU does not have automatic refresh function (example: AnA series CPU)
Data is transferred to the refresh buffer of the master station directly by sequence ladder logic to perform communication
with the remote devices.

3 INVERTER SETTING
3.1 Pre-Operation Setting
3.1.1 Inverter station n u m b er setting
Set the inverter station number before switching on the inverter and do not change the setting while power is on.
When setting the station number, the following points should be taken into consideration:
1) The station number may be set between 1 and 64.
Fully note that if the station number is changed during operation, data communication cannot be made with the new
station number.
2) Setting method
z
Set the arrow (×) of the corresponding switch to the required numeral.
Example:
y
For station number 1: Set (×) of ×10 to "0" and (×) of ×1 to "1".
y
For station number 26: Set (×) ×10 to "2" and (×) ×1 to "6".
z
Set station numbers consecutively in a connection sequence.
(The station numbers may also be set independently of the connection sequence.)
z
Note that the same station number cannot be repeated.
(If the same station number is repeated, proper communication cannot be made.)
z
Set each station number switch to the position of its numeral without error. If it is set to any
position between numerals, normal data communication cannot be made.
