Specifications of Options and Peripheral Devices
The following options and peripheral devices can be used for the Inverter. Select them according to the
application.
*Use a ground fault interrupter with a current sensitivity of 200 mA minimum and an operating time of 0.1 s minimum to prevent
operating errors. The interrupter must be suitable for high-frequency operation.
Example:NV series by Mitsubishi Electric Corporation (manufactured in or after 1988)
EG, SG series by Fuji Electric Co., Ltd. (manufactured in or after 1984)

Purpose Name Model (Code) Description
Protect Inverter wiring
MCCB or Ground
Fault Interrupter
*
Example: Mitsubishi
Electric’s NV Series
Always connect a breaker to the power supply line to pro-
tect Inverter wiring. Use a ground fault interrupter suitable
for high frequencies.
Prevents burning when
a Braking Resistor is
used.
Magnetic Contac-
tor
Example: Fuji Electric’s
SC Series
Install to prevent the braking resistor from burning out
when one is used. Always attach a surge absorber to the
coil.
Contains switching
surge
Surge Absorber DCR2-o
Absorbs surge from the magnetic contactor and control
relays. Connect surge absorbers to all magnetic contactors
and relays near the Inverter.
Isolates I/O signals Isolator DGPo
Isolates the I/O signals of the Inverter and is effective
against inductive noise.
Improve the input
power factor of the
Inverter
DC Reactor
AC Reactor
3G3HV-PUZDABo
3G3IV-PUZBABo
Used to improve the input power factor of the Inverter. All
Inverters of 22 kW or higher contain built-in DC reactors.
These are optional for Inverters of 18.5 kW or less. Install
DC and AC reactors for applications with a large power
supply capacity (600 kVA or higher).
Reduce the affects of
radio and control device
noise
Input Noise Filter
3G3IV-PFNo
3G3EV-PLNFo
Reduces noise coming into the inverter from the power
supply line and to reduce noise flowing from the inverter
into the power supply line. Connect as close to the
Inverter as possible.
Output Noise Fil-
ter
3G3IV-PLFo
Reduces noise generated by the Inverter. Connect as close
to the Inverter as possible.
Enable stopping the
machine in a set time
Braking Resistor 3G3IV-PERF150WJo01
Consumes the regenerative motor energy with a resistor to
reduce deceleration time (use rate: 3% ED).
Braking Resistor
Unit
3G3IV-PLKEBo
Consumes the regenerative motor energy with a resistor to
reduce deceleration time (use rate: 10% ED).
Braking Unit 3G3IV-PCDBRoB
Used with a Braking Resistor Unit to reduce the decelera-
tion time of the motor.
Operates the Inverter
externally
Analog Operator
(small plastic
Operator)
3G3IV-PJVOP95o
Allows frequency reference settings and ON/OFF opera-
tion control to be performed by analog references from a
remote location (50 m max.).
Frequency counter specifications: 60/120 Hz, 90/180Hz
Analog Operator
(Standard steel-
plate Operator)
3G3IV-PJVOP96o
Allows frequency reference settings and ON/OFF opera-
tion control to be performed by analog references from a
remote location (50 m max.).
Frequency counter specifications: 75 Hz, 150 Hz, 220 Hz
Digital Operator
Connection Cable
1 m cable: (3G3IV-
PCN126)
3 m cable: (3G3IV-
PCN326)
Extension cable to use a Digital Operator remotely.
Cable length: 1 m or 3 m

Unit
3G3IV-PCNo26
Handles momentary power losses for the control power
supply for models 2.2 kW or less (maintains power for
2s).
