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:

Use the power supply within the
Power supply permissible power supply specifications
of the high power factor converter.
Earth leakage The breaker should be selected with
circuit care since a large inrush current flows
breaker or no-fuse in the high power factor converter at
breaker power on.
Install the magnetic contactor to
ensure safety.

or stop the inverter. It might reduce
the high power factor converter life.
Make sure that the reactor has a
Reactor 1
proper capacity which matches the
FR-HCL01
high power factor converter capacity.
Make sure that the external box has a
External box
proper capacity which matches the
FR-HCB

High power factor Note: Do not install a no-fuse breaker
converter (NFB) across terminals P-P and
N-N of the high power factor
converter and the inverter.
Make sure
