11.3 Options and Peripheral Devices
Purpose Name Model (Code) Descriptions
Protect Invert-
er wiring MCCB or Ground
Fault Interrupter
NF *1
Always connect a breaker to the power supply line to pro-
tect Inverter wiring. Use a ground fault interrupter suitable
for high frequencies.
Prevents burn-
ing when a
Braking Resis-
tor is used.
Magnetic Contactor HI- E
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 in-
put power fac-
tor of the In-
verter
DC Reactor
AC Reactor
UZDA-
UZBA-
Used to improve the input power factor of the Inverter. All
VS-626MC5 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 af-
fects of radio
and control de- Input Noise Filter
Single-phase: LNFB-
3-phase: LNFD- HF
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.
and control de-
vice noise
Output Noise Filter LF- Reduces noise generated by the Inverter. Connect as close
to the Inverter as possible.

* 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.
* 2. The suffixes of the model and code numbers of VS Operators indicate frequency meters are shown in the following table.
