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)

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.

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 DGP
o
Isolates
the I/O signals of the Inverter and is effective
against
inductive noise.

Reactor
3G3HV-PUZDAB
o
3G3IV-PUZBAB
o
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).

Input
Noise Filter
3G3IV-PFN
o
3G3EV-PLNF
o
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.

Noise Fil-
ter
3G3IV-PLF
o
Reduces
noise generated by the Inverter. Connect as close
to
the Inverter as possible.
