1.1.3 Handling precautions
The following system is required to operate the inverter. Install the high power factor converter in a proper
position. For the selection and specifications of each peripheral device, refer to “Precautions for Selecting
Peripheral Devices” on page 52:
Name Description Refer to Page:
Power supply
Use the power supply within the
permissible power supply specifications
of the high power factor converter.
56
Earth leakage
circuit
breaker or no-fuse
breaker
The breaker should be selected with
care since a large inrush current flows
in the high power factor converter at
power on.
55
Magnetic
contactor
Install the magnetic contactor to
ensure safety.
When installed, do not use it to start
or stop the inverter. It might reduce
the high power factor converter life.
55
Reactor 1
FR-HCL01
Make sure that the reactor has a
proper capacity which matches the
high power factor converter capacity.
62
External box
FR-HCB
Make sure that the external box has a
proper capacity which matches the
high power factor converter capacity.
64
Reactor 2
FR-HCL02
Make sure that the reactor has a
proper capacity which matches the
high power factor converter capacity.
62
High power factor
converter
Install and wire the equipment
correctly.
Note: Do not install a no-fuse breaker
(NFB) across terminals P-P and
N-N of the high power factor
converter and the inverter.
13
Inverter
Make sure that the inverter is
compatible with the FR-HC.
Connect the inverter suitable for the
capacity of the high power factor
converter.
56
Devices
connected to the
output
Do not connect a power capacitor,
surge suppressor or radio noise filter
to the output side.
Instruction

Note: When installing a no-fuse
breaker (NFB) on the output
side, contact the NFB
manufacturer for selection of
no-fuse breaker.
