Specifications of Options and Peripheral Devices
The following options and peripheral devices can be used for the Inverter. Select them according to the
application.
* 1. 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)
* 2. The finement zero-phase reactor is manufactured by Hitachi Metals.

Protect Inverter wiring
MCCB or Ground
Fault Interrupter
*1
NF
Always connect a breaker to the power supply line to protect
Inverter wiring. Use a ground fault interrupter suitable for high
frequencies.
Prevents burning when
a Braking Resistor is
used.
Magnetic
Contactor
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-
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 DGP
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
UZDA-
UZBA-
Used to improve the input power factor of the Inverter. All
Inverters of 18.5 kW or higher contain built-in DC reactors.
These are optional for Inverters of 15 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
LNFD-
FN-
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.
Finemet zero-
phase reactor to
reduce radio
noise

Reduces noise from the line that sneaks into the Inverter input
power system. Insert as close to the Inverter as possible.
Can be use on both the input side and output side.
Output Noise Fil-
ter
LF-
Reduces noise generated by the Inverter. Connect as close to
the Inverter as possible.
Enable stopping the
machine in a set time
