Converter and peripheral devices
Three-phase AC power supply
Use within the permissible power
supply specifications of the converter.
Moulded case circuit breaker (MCCB) or
earth leakage current breaker (ELB),
fuse
The breaker must be selected carefully since
an inrush current flows in the converter at
power ON.
Magnetic contactor (MC)
Install the magnetic contactor to
ensure safety.
Do not use this magnetic contactor to
start and stop the high power factor
converter and the inverter. Doing so will
shorten the life of the inverter and the
converter.
Reactor 1 (FR-HCL21)
Confirm that the capacity of the reactor
is selected according to the capacity of
the converter.
(Refer to page 35, 49)
Outside box (FR-HCB2)∗
Check that the capacity of the outside box
matches with the capacity of the high power
factor converter.
(Refer to page 34)
∗Outside box is not available for 280K or higher.
Connect filter capacitors, inrush current limit
resistors, and magnetic contactors.
Reactor 2 (FR-HCL22)
Confirm that the capacity of the reactor
is selected according to the capacity of
the converter.
Devices connected to the output
Do not install a power factor correction capacitor,
surge suppressor or radio noise filter on the output
side of the inverter. When installing a moulded case
circuit breaker on the output side of the inverter,
contact each manufacturer for selection of the
moulded case circuit breaker.
Earth (Ground)
To prevent an electric shock, always earth (ground)
the motor and inverter.
R4S4 T4
(Refer to page 35, 49)
Converter and peripheral devices
High power factor converter
(FR-HC2)
Install and wire correctly.
Do not install the moulded case circuit
breaker (MCCB) between terminals P
and P, or N and N of the converter
and the inverter.
(Refer to page 34, 47)

Fuse
Installation of a fuse is recommended
for safety.
Select a fuse according to the
connected motor capacity.
(Refer to page 12)
Inverter
Confirm that this is a FR-HC2
supporting inverter. (Refer to the
inverter catalogs for compatible
inverters.)
Connect an inverter that corresponds
with the each capacity of the converter.
Match the control logic (sink logic /
source logic) of the converter and the
inverter.
Motor
Connect the motor corresponds to the
each capacity.
