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.

Low-voltage manual switch
Connect it in any application where the motor is run
by the load after the drive unit has been powered off.
Refer to: Page 3, 1. Operation
Do not turn this switch on/off during drive unit
operation (output).
Motor
Power equipment capacity
As the power equipment capacity,
select the kVA value not less than
the one given in the specifications.
Refer to: Chapter 7, 7.1.1
Standard specifications
Magnetic contactor
Install it when switching power
on/off by remote operation.
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.
Heavy-duty brake resistor
(FR-ABR)
Connect it to increase braking
capability for deceleration.
BU brake unit
Connect it to increase braking
capability for deceleration.
This unit is used with a
discharge resistor.
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.
