Thank you for choosing this Mitsubishi Inverter plug-in option.
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.
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 even 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.

CAUTION
SAFETY INSTRUCTIONS
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 or wiring 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, 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 the 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 pinching. Otherwise you may get an electric
shock.

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 polarity is correct to prevent damage, 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.
CAUTION
•Do not install or operate the plug-in option 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 conductive bodies such as screws and metal
fragments or other flammable substance such as oil from
entering the inverter.
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 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,
reset the required parameters before starting operations.
Each parameter returns to the initial value.
•For prevention of damage due to static electricity, touch
nearby metal before touching this product to eliminate static
electricity from your body.
CAUTION
•Do not test the equipment with a megger (measure insulation
resistance).
CAUTION
•Treat as industrial waste.
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.

2INSTALLATION AND WIRING
2.1 Pre-Installation Instructions
Make sure that the input power of the inverter is off.
CAUTION
With input power on, do not install or remove the plug-in option. Otherwise, the inverter and
plug-in option may be damaged.

INSTALLATION AND WIRING
2.2 Installation Procedure
1) Remove the inverter front cover.
2) Mount the hex-head screw for option
mounting into the inverter screw hole (on
earth plate). (size 5.5mm, tightening
torque 0.56N⋅m to 0.75N⋅m)
3) Securely fit the connector of the plug-in
optiontotheinverterconnector alongthe
guides.
4) Securely fix the both right and left sides
of the plug-in option to the inverter with
the accessory mounting screws. If the
screwholes donotline-up,theconnector
may not have been plugged snugly.
Check for loose plugging.
REMARKS
After removing two screws on the right and left
places, remove the plug-in option.
(The plug-in option is easily removed if the
control circuit terminal block is removed before.)
CAUTION
1. When the inverter can not recognize that the option unit is mounted due to improper installation, etc.,
" " (option alarm) is displayed.
2. Note that a hex-head screw for option mounting or mounting screw may drop during mounting and removal.

2.3 Wiring
(1) Strip off the sheath of the cable to wire.
Strip off the sheath about the size below. If the length of the sheath pealed is too long, a short circuit
may occur among neighboring wires. If the length is too short, wires might come off.
(2) Loosen the terminal screw and insert the cable into the terminal.

INSTALLATION AND WIRING
(3) For wiring of the 30K(00620 (EC Version)) or less, route wires between the control circuit terminal block
and front cover. If cables can not be routed between the control circuit terminal block and front cover due
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
terminal block.
REMARKS
When wires can not be connected to the terminal block due to parallel connection or will not fit in the wiring space due
to large gauge or the increased number of cables, perform wiring by using a junction terminal block, etc.
Do not use empty terminals as junction terminals because they are used in the option unit. If
they are used as the junction terminals, the option unit may be damaged.
When installing the inverter front cover, the cables to the inverter's control circuit terminals and
option unit terminals should be routed properly in the wiring space to prevent them from being
caught between the inverter and its cover.
After wiring, wire offcuts must not be left in the inverter. They may cause a fault, failure or
malfunction.
Cut off a hook on the inverter
front cover side surface.
(Cut off so that no portion is left.)
Cut off
with a
nipper,
etc.
