Thank you for choosing the Mitsubishi inverter option unit.
WARNING
CAUTION
This instruction manual gives handling information and
precautions for use of this equipment. Incorrect handling might
cause an unexpected fault. Before using the equipment, please
read this manual carefully to use the equipment to its optimum.
Please forward this manual to the end user.
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 CAUTION 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
1. Electric Shock Prevention
WARNING
While the inverter power is ON, do not open the front cover. Do
not run the inverter with the front cover removed.
Otherwise you may access the exposed high voltage terminals
or the charging part of the circuitry and get an electric shock.
Before starting wiring or inspection, check that the operation
panel indicator 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 inverter before wiring. Otherwise, you may
get an electric shock or be injured.
Operate the keys with dry hands to prevent an electric shock.

To prevent injury, damage or product failure, please note the
following points.
(1) Transportation and mounting
CAUTION
Do not install and operate the parameter unit (FR-PU04/PU04V)
if it is damaged or has parts missing.
Do not stand or rest heavy objects on this equipment.
Check the inverter mounting orientation is correct.
The parameter unit (FR-PU04/PU04V) is a precision device. Do
not drop it or subject it to impact.
Use the inverter under the following environmental conditions:
*Temperatures applicable for a short time, e.g. in transit.
If halogen-based materials (fluorine, chlorine, bromine, iodine,
etc.) infiltrate into a Mitsubishi product, the product will be
damaged. Halogen-based materials are often included in
fumigant, which is used to sterilize or disinfest wooden packages.
When packaging, prevent residual fumigant components from
being infiltrated into Mitsubishi products, or use an alternative
sterilization or disinfection method (heat disinfection, etc.) for
packaging. Sterilization of disinfection of wooden package should
also be performed before packaging the product.
A-2
(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
Since pressing key may not stop output depending on
the function setting status, provide a circuit and switch
separately to make an emergency stop (power OFF,
mechanical brake operation for emergency stop, etc).
Make sure that the start signal is off before resetting the inverter
alarm. A failure to do so may restart the motor suddenly.
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, each
parameter returns to the factory setting. Re-set the required
parameters before starting operation.
(4) Corrective actions for alarm
CAUTION
Provide safety backup devices, such as an emergency brake,
to protect machines and equipment from hazard if the
parameter unit (FR-PU04/PU04V) becomes faulty.
(5) Disposal
CAUTION
Treat as 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.

REMARKS
· Setting from the help menu is also available. For
details refer to page 42.
· When "Current monitor" or "Power monitor" is selected,
note that any current or power not more than 5% of the
rated inverter current cannot be detected and displayed.
Example: When a small motor is rotated with a large-
