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.

Purpose Name Model (Code) Descriptions

Protect MxC

wiring

MCCB or

Ground Fault

Interrupter

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.

(300-001-041)

Reduces noise from the line that sneaks into the MxC

input power system. Insert as close to the MxC as

possible.

Can be use on both the input side and output side.

Output Noise

Filter

LF-

Reduces noise generated by the MxC. Connect as

close to the MxC as possible.
