Thank you for choosing this Mitsubishi Inverter plug-in option.
This instruction manual gives handling information and
precautions for use of this equ ipment. Incorr ect handling might
cause an une xpected 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

CAUTION
Note that even the level may lead to a se rious
consequence according to conditions. Please follow the
instructions of both levels because they are important to
personnel safety.

Assumes that incorrect handling may
cause hazardous conditions, resulting
in medium or slight injury, or may
cause physic al damage only.
CAUTION
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 inver ter with the front cover or wiring cover
removed. Otherwise, you may access the exposed highvoltage terminals and charging part and get an electric shock.
• If power is off, do not remove the front cover except for wiring
or periodic inspec tion. You may access the char ged 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. 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 plug-in option before wiring. Otherwise,
you may get an electric shock or be injured.
• Do not touch t he plug-in option with wet hands. Otherwise
you may get an electric shock.
• Do not subject the cables to scratches, excessive stress,
heavy loads or pin ching. Otherwise you m ay get an electric
shock.
A-1
2. Injury Prevention
3) Usage
CAUTION
• Apply only the voltage specified in the instruction manual to
each terminal. Otherwise, burst, damage, etc. may occur.
• Ensure that the cables are connected to the correct terminals.
Otherwise, burst, damage, etc. may occur.
• Always make sure that pol arit y is correct to prevent dam age, etc.
Otherwise, burst, damage may occur.
• 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 follo wing points to prevent an accidental fail ure,
injury, electric shock, etc.
1) Transportation and mounting
CAUTION
• Do not install or o pe ra te th e plug-in opti on 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 other cond uctive bodies such as screws and metal
fragments or other flammable substance such as oil from
entering the inverter.
2) Trial run
CAUTION
• Before starting operation, confirm and adjust the parameters.
A failure to do so may cause some machines to make
unexpected motions.
WARNING
• Do not modify the equipment.
• Do not perform parts removal whic h is not instruct ed in this
manual. Doing so may lead to fault or damage of the inverter.
CAUTION
• When parameter clear or all parameter clear is performed,
reset the required parameters before starting operations.
Each parame ter returns to the initial value.
• For prevention of damage due to static electricity, touch
nearby metal before touch ing this prod uct to elimin ate static
electricity from your bo dy.
4) Maintenance, inspection and parts replacement
CAUTION
• Do not test the equipment with a megger (measure insulation
resistance).
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.

to the increased number of cables, remove a hook of the front cover and use a space become available.
For wiring of the 37K(00770 (EC Version)) or more, use the space on the left side of the control circuit

4.6 Instructions
(1) A voltmeter having smaller internal impedance (or an ammeter having larger internal impedance) than
the value indicated in the Specifications may not deflect to full-scale and may not be calibrated.
(2) When calibrating a meter which has a small full-scale value, set the output of terminal AM0 (or AM1) to
the minimum without the meter connected. Then, connect the meter and make calibration.
AUTION
This option unit is factory-set to provide the full-scale output of 10VDC and 20mADC. Hence, a
voltmeter (7VDC or less) or an ammeter (14mADC or less) with a small full-scale value may be
damaged accidentally during calibration. This should be fully noted.
(3) Set
(4) When an option error occurs, all outputs are tuned off.
"0%" in Pr. 307 (Pr . 31 1) and "100%" in Pr. 308 ( Pr. 312) when calibrating Pr . 323, Pr. 324, C0 (Pr. 900),
C1 (Pr. 901) when Pr. 309 =
"10 or 11 " to prevent calibration value deviation.

5.2 Terminals
By setting the Pr. 313 to Pr. 319 values, output signals available with an inverter as standard can be output
from the open collector terminals.
(1) Open collector output specifications: Permissible load 24V, 0.1ADC
(2) The circuit logic is the same as that of the inverter.
For details of changing the control logic, refer to the inverter manual (basic).
