Safety instructions
Thank you for choosing this Mitsubishi Electric inverter plug-in option.
This Instruction Manual provides handling information and precautions for use of this product. Incorrect handling might cause an unexpected fault. Before
using this product, always read this Instruction Manual carefully to use this product correctly.
Please forward this Instruction Manual to the end user.
Electric Shock Prevention
WARNING
While the inverter power is ON, do not open the front cover or the wiring cover. Do not run the inverter with the front cover or the wiring cover
removed. Otherwise you may access the exposed high voltage terminals or the charging part of the circuitry and get an electric shock.
Do not remove the inverter front cover even if the power supply is disconnected. The only exception for this would be when performing wiring
and periodic inspection. You may accidentally touch the charged inverter circuits and get an electric shock.
Before wiring or inspection, LED indication of the inverter unit operation panel must be switched OFF. Any person who is involved in wiring or
inspection shall wait for at least 10 minutes after the power supply has been switched OFF and check that there is no residual voltage using
a tester or the like. For some time after the power-OFF, a high voltage remains in the smoothing capacitor, and it is dangerous.
Any person who is involved in wiring or inspection of this product shall be fully competent to do the work.
The plug-in option must be installed before wiring. Otherwise you may get an electric shock or be injured.
Do not touch the plug-in option or handle the cables 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.
WARNING Incorrect handling may cause hazardous conditions, resulting in death or severe injury.
Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material
damage.
Do not attempt to install, operate, maintain or inspect the product until you have read through this Instruction Manual and supplementary
documents carefully and can use the equipment correctly. Do not use this product until you have a full knowledge of this product mechanism,
safety information and instructions. In this Instruction Manual, the safety instruction levels are classified into "WARNING" and "CAUTION".

NOTE
• Be careful not to drop mounting screws during the installation or removal of the plug-in option.
• Only 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. (For the positions of the option connectors 1 to 3, refer to page 11.)
• When the inverter cannot recognize the option due to improper installation or any other reason, the protective function (E.1
to E.3) is displayed. 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.

2.4 Wiring
1. Use twisted pair shield cables (0.2 mm2or larger) to connect the FR-A8AP and position detector.
For the wiring to the terminals PG and SD, use several cables in parallel or use a thick cable, according to the wiring
length. To protect the cables from noise, run them away from any source of noise (e.g. the main circuit and power
voltage).
Wiring length Parallel connection
(Cable gauge 0.2 mm2)Larger-size cable
Within 10 m At least two cables in parallel 0.4 mm2or larger
Within 20 m At least four cables in parallel 0.75 mm2or larger
Within 100 m*1 At least six cables in parallel 1.25 mm2or larger

*1 When differential driver is set and a wiring length is 30 m or more
The wiring length can be extended to 100 m by slightly increasing the 5 V power supply (approx. 5.5 V) and using six or more cables with
gauge size of 0.2 mm2in parallel or a cable with gauge size of 1.25 mm2or more. Note that the voltage applied should be within power
supply specifications of encoder.
To reduce noise of the encoder cable, earth (ground) the encoder shielded cable to the enclosure (as close as the inverter) with
a P clip or U clip made of metal.
NOTE
• For details of the optional encoder dedicated cable (FR-JCBL/FR-V7CBL), refer to page 22
• FR-V7CBL is provided with a P clip for earthing (grounding) shielded cable.

2. Wire the shielded twisted pair cable after stripping its sheath to make its cables loose.
Also, protect the shielded cable of the shielded twisted pair cable to ensure that it will not make contact with the
conductive area.
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.
Use a crimp terminal as necessary.
When using the crimp terminal, make sure that the stranded wire do not come out of the terminal.
