Always connect either of the above for
circuit (wiring) protection. Make selection
in accordance with the selection table.
Choose the earth leakage circuit breaker
which has harmonic suppression.
No-fuse breaker or earth leakage
circuit breaker
Refer to: 2.2.2 Selection of peripheral
devices
Reactor (FR-BAL)
Install it for power factor improvement,
power coordination, or harmonic
suppression.
Radio noise filter (FR-BIF)
Connect it to reduce radio noise
in the AM frequency band.
This filter is designed for use on
the input side only.

connector
Magnetic contactor
Make selection in accordance
with the selection table.
Refer to: 2.2.2 Selection of
peripheral devices
Line noise filter
(FR-BSF01) (FR-BLF)
Connect it to reduce high
frequency noises outgoing to the
power supply side.
Its effect is higher as the number
of wire turns is greater.
Main circuit cables
Choose the wire size in
accordance with the selection
table.
Refer to: 2.2.2 Selection of
peripheral devices
Reactor (FR-BEL)
Install it for power factor
improvement, power
coordination, or harmonic
suppression.
Brake resistor (MRS)
(FR-ABR)
Connect it to increase braking
capability for deceleration.
Line noise filter
(FR-BSF01) (FR-BLF)
Connect it to reduce high
frequency noises outgoing to
the output side.
When installing it on the output
side, do not turn the wire more
than four times.
Magnetic motor
Use the specified motor.
It cannot be run using
commercial power.
BU brake unit, Discharge
resistor
Connect it to increase braking
capability for deceleration.
