Specifications for Options and Peripheral Devices
The following options and peripheral devices can be used for the MxC. Select them according to the
application.
* 1. Use an earth leakage breaker that has harmonics protection and a minimum current of 30 mA per MxC. Otherwise, the harmonic leakage current may cause a mal-
function. If a malfunction occurs in an earth leakage breaker without harmonic protection, lower the carrier frequency of MxC, replace the earth leakage breaker
with one that has harmonic protection, or raise the current of the earth leakage breaker to 200 mA or more per MxC.
* 2. The FINEMET zero-phase reactor is manufactured by Hitachi Metals.

Ground Fault
Interrupter
*1
NF†
Always connect a breaker to the power supply line to
protect MxC wiring. Use a ground fault interrupter
suitable for high frequencies.
Prevents burning
of the MxC. Magnetic Con-
tactor
SC series
Install to prevent the MxC from burning out when
faults occur at the input terminal side of the MxC.
Always attach a surge absorber to the coil.
Contains switch-
ing surge
Surge Absorber DCR2-†
Absorbs surge from the magnetic contactor and con-
trol relays. Connect surge absorbers to all magnetic
contactors and relays near the MxC.
Isolates I/O
signals
Isolator DGP†
Isolates the I/O signals of the MxC and is enabled
against inductive noise.
Reduces the
affects of radio
and
control device
noise
Input Noise
Filter LNFD-†
FN-†
Reduces noise coming into the MxC from the power
supply line and to reduce noise flowing from the
MxC into the power supply line. Connect as close to
the MxC as possible.
