1. Electric Shock Prevention
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".
Assumes that incorrect handling may cause hazardous conditions, resulting in
death or severe injury.
Assumes that incorrect handling may cause hazardous conditions, resulting in
medium or slight injury, or may cause physical damage only.
Note that the level may lead to a serious consequence according to conditions. Please follow the
instructions of both levels because they are important to personnel safety.
SAFETY INSTRUCTIONS
!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.
!Even 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 the inverter power indicator lamp 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..

3. Additional Instructions
Also note the following points to prevent an accidental failure, injury, electric shock, etc.:
(1) Transportation and mounting
(2) Test operation and adjustment
!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.
!Handle this option unit 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 or for some time after power-off, do not touch the inverter as it is hot and you may get burnt.
!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 or other conductive bodies oroil or other flammable substance from entering the inverter.
!Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to
make unexpected motions.

1.PRE-OPERATION INSTRUCTIONS
1.1 Unpacking and Product Confirmation
Take the option unit out of the package, check the unit name, and confirm that the product is as you ordered and
intact.
This product is a plug-in option unit designed for exclusive use in the Mitsubishi FR-V500 series vector inverter.
Before using it, check the type and SERIAL number of the inverter.
• This product may be used with the FR-V520-1.5k to 55k series manufactured in and after May 2002. Any of the
models may be used with this unit if its SERIAL number indicated on the rating plate and package has
""25""""""" or later version. For details on the SERIAL number, please contact your sales
representative.
SERIAL is made up of 1 version symbol, 1 alphabet letter or numeric character indicating month, and 7 numeric
characters indicating the year and control number as shown below. (Only the first three digits of the control
number are printed on the package.)

PRE-OPERATION INSTRUCTIONS
1.5 Operation Overview
In communication with the Mitsubishi motion controller, the inverter operation (speed control or position
control or torque control under vector control with encoder), monitoring, or parameter setting can be
performed from a program on the motion controller.
SSCNET enables less wiring, improved reliability, improved synchronous control performance and motion
controller-driven multi-axis batch control.
CAUTION
The inverter can perform vector control with encoder (speed control, position control, torque
control) under the command from the motion controller. (Pr. 800 "control system selection" is
made invalid.)
