Remarks for using earth leakage circuit breakers in the mains supply:
Frequency inverters with CE-filters (RFI-filter) and screened motor
cables have a higher leakage current against earth. Especially in the
moment of switching on this can cause unintentional triggerings of
earth leakage circuit breakers. Because of the rectifier on the input
side of the inverter there is the possibility to stall the switch-off
function through amounts of DC-current. The following should be
observed:
Only short time-invariant and pulse current-sensitive earth leakage
circuit breakers with higher trigger current should be used.
Other components should be secured with separate earth leakage
circuit breakers.
Earth leakage circuit breakers in front of an inverter are not an
absolute protection against direct touching.
Be sure to set the fuse(s) (the same phase as the main power supply)
in the operation circuit.
Otherwise, there is a danger of fire.
As for motor leads, earth leakage breakers and electromagnetic
contactors, be sure to use the equivalent ones with the specified
capacity (rated).
Otherwise, there is a danger of fire.

If there is a possibility that such an occurrence may harm humans, than install an electromagnetic
contactor (Mc0) on the power supply side, so that the circuit does not allow automatic restarting
after the power supply recovers. If the optional remote operator is used and the retry function has
been selected, this will also cause automatic restarting when an operation instruction has been
input, so please be careful.

(If the lamp is lit or still flickering, then the internal capacitor's residual voltage is still dangerous.)
MOTOR TERMINAL SURGE VOLTAGE SUPPRESSION FILTER
(FOR THE 400V CLASS)
In a system using an inverter of the voltage control PWM system, a surge voltage caused by the
cable constants such as the cable length (especially when the distance between the motor and
inverter is 10m or more) and cabling method may occur at the motor terminal.
A dedicated filter of the 400V class for suppressing this surge voltage is available, please order
one.
PROTECTION AGAINST NOISE INTERFERENCE FROM INVERTER
The inverter uses many semiconductor switching elements such as transistors and IGBTs. Thus, a
radio set or measuring instrument located near the inverter is susceptible to noise interference.
To protect the instruments from erroneous operation due to noise interference, they should be
installed well apart from the inverter. It is also effective to shield the whole inverter structure.
Addition of an EMI filter on the input side of the inverter also reduces the effect of noise from
commercial power line on external devices.
Note that external dispersion of noise from the power line can be minimized by connecting an
EMI filter on the primary side of inverter.

EFFECTS OF DISTRIBUTOR LINES ON INVERTERS
In the cases below involving a general-purpose inverter, a large peak current flows on the power
supply side, sometimes destroying the converter module. Where such situations are foreseen, or
the paired equipment must be highly reliable, install an AC reactor between the power supply and
the inverter.
(A) The unbalance factor of the power supply is 3% or higher.
(B) The power supply capacity is at least 10 times greater than the inverter capacity (and the
power supply capacity, 500kVA or more).
(C) Abrupt power supply changes are expected.
Examples:
(1) Several inverters are interconnected with a short bus.
(2) A thyristor converter and an inverter are interconnected with a short bus.
(3) An installed phase advance capacitor opens and closes.
In cases (A), (B) or (C), we recommend installing an AC reactor of 3%(in a voltage drop at
rated current) with respect to the supply voltage on the power supply side.

parallel with the relay (RY). Otherwise, the surge voltage created when the relay (RY)
goes ON or OFF may damage the output intelligent terminal circuit.
NOTE2:
Use a twisted and shielded wire for the signal line, and cut the shielded covering as shown
in the diagram below. Make sure that the length of the signal line is 20meters or less.

When the frequency setting signal is turned on and off with a contact, use a relay which
will not cause contact malfunctions, even with the extremely weak currents and voltages,
such as crossbar twin contacts, etc.
Use relays which do not have contact defects at 24V DC, 3mA for the other terminals.
Separate the main circuit wiring from the relay control circuit wiring. If they must cross,
be sure that they cross at a right angle.

AC reactor for
reducing vibration
(ACL-L-)
(ACL-H-)
Using the inverter may cause noise on the peripheral equipment through the
power lines.
This part reduces noise.
This part reduces common noise generated between the power supply and the
ground, as well as normal noise.
Put it in the primary side of inverter.
NOTE5
This part is used for applications that needs to increase the brake torque of
the inverter or to frequently turn on and off and to run high inertia load.
This part reduces noise generated at the output of the inverter.
(It is possible to use for both input and output)
Running motors with the inverter generates vibration greater than that with
commercial power supply.
This part installed between the inverter and motor reduces torque ripple.
When the cable length between the inverter and motor is long, a
countermeasure for a malfunction of the termal relay is taken.
