1.1 Basic configuration
Power supply
Use within the permissible power supply
specifications of the inverter. (Refer to page 62.)
No-fuse breaker or earth leakage circuit breaker
The breaker must be selected carefully since an in-
rush current flows in the inverter at power on.
Magnetic contactor
Install for your safety. Do not use this magnetic
contactor to start and stop the inverter. Doing so will
cause the inverter life to be shorten. (Refer to page
12.)
Installation of a reactor
A reactor must be used when the power factor is to
be improved or the inverter is installed near a large
supply system (500kVA or more and wiring distance
within 10 m).
Make the selection carefully.
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 no-fuse breaker on the output side
of the inverter, contact each manufacturer for
selection of the no-fuse breaker.
Earth (Ground)
To prevent an electric shock, always earth (ground)
the motor and inverter.
For reduction of induction noise from the power line
of the inverter, it is recommended to wire the earth
(ground) cable by returning it to the earth (ground)
terminal of the inverter.

Control circuit
3.3.4 Power-off and magnetic contactor (MC)
(1) Inverter primary side magnetic contactor (MC)
On the inverter's primary side, it is recommended to provide an MC for the following
purposes. (Refer to page 3 for selection)
1) To release the inverter from the power supply when the inverter protective function
is activated or the drive becomes faulty (e.g. emergency stop operation)
When cycle operation or heavy-duty operation is performed with an optional brake
resistor connected, overheat and burnout of the electrical-discharge resistor can be
prevented if a regenerative brake transistor is damaged due to insufficient heat
capacity of the electrical-discharge resistor and excess regenerative brake duty.
2) To prevent any accident due to an automatic restart at restoration of power after an
inverter stop made by a power failure
3) To rest the inverter for an extended period of time
The control power supply for inverter is always running and consumes a little power.
When stopping the inverter for an extended period of time, powering off the inverter
will save power slightly.
4) To separate the inverter from the power supply to ensure safe maintenance and
inspection work
As the inverter's primary MC is used for the above purposes, select the one of class
JEM1038-AC3 for the inverter input side current when making an emergency stop
during normal operation.
(2) Handling of secondary side magnetic contactor
In principle, do not provide a magnetic contactor between the inverter and motor and
switch it from off to on during operation. If it is switched on during inverter operation, a
large inrush current may flow, stopping the inverter due to overcurrent shut-off. When
an MC is provided for switching to the commercial power supply, for example, switch it
on/off after the inverter and motor have stopped.
REMARKS
The MC may be switched on/off to start/stop the inverter. However, since reapeated inrush
currents at power on will shorten the life of the converter circuit (switching life is about 100,000
times), frequent starts and stops must be avoided. Turn on/off the inverter start controlling
terminals (STF, STR) to run/stop the inverter.
As shown on the right,
always use the start signal
(ON or OFF across
terminals STF or STR-SD)
to make a start or stop.
