Application and precautions of Peripherals
Power Source
lApply the power source at the correct rated voltage to prevent
from damaging the inverter.
l
A Power Disconnect or Circuit breaker must be installed between
the AC power supply and the inverter.
Molded-case circuit breaker:
lUtilize appropriate circuit breaker suitabl
e for the rated voltage
and current ratings of the inverter to switch ON/OFF the power
supply to the inverter and as a protection for the inverter.
l
Do not operate the circuit breaker to switch ON or OFF the
inverter and operational sequence motor’s run/stop.
Leakage circuit breaker:
l
Leakage circuit breaker should be added to prevent false
operation cause by leakage current and to ensure personnel
safety.
Magnetic Contact:
l
The Magnetic Contact can be omitted at ordinary operation. To
utilize external contr
ol, automatic restart, or breaking controller
the magnetic contact must be added at the primary side.
l
Do not operate the magnetic contact to switch ON or OFF the
inverter.
Power improvement AC Reactor:
lIf large capacity power source is applied (over 600KV
A),
additional AC reactor may be added to improve power factor.
Inverter:
l
Power supply input terminals L1 and L2 is not differentiated on
phase sequence, they can be arbitrarily connected. Their
connection may be exchanged.
lOutput terminal T1, T2, and T3
should be connected to the U, V,
and W terminals of the motor respectively. If motor turns in
opposite direction of the inverter, simply exchanging two of three
wire connection may correct this problem.
lOutput terminal T1, T2, and T3 must not be connected
to power
source to prevent from damaging inverter.

External wiring should be carried out in accordance with following requirement. Check and reassure
the wiring is correct after the wiring is complete. (Do not utilize the control circuitry buzzer to check
the wiring.)
EMI connecting:
It is very important that the connections between the inverter, the shielded motor cable, and the EMI
filters are tested as follows.
lUse a metal grounding plate and place the frequency inverter and the EMI filter on the plate.
lUse a screened motor cable with 4 connectors ( U,V,W,& Earth ), don’t use the shielding as
safety earth ( shield is high frequency earth )
lRemove painting around the two metal coupling nut holes. So that the metal coupling nuts
( and the shielding ) make contact with the frequency inverter and the motor.
lDon't solder a conductor to the shielding
lUse a metal clamp to connect the shielding from the motor cable with the metal grounding
plate. Now there is a perfect high frequency earth connection between frequency inverter .
grounding plate and EMI filter.
lKeep the distance between frequency inverter and EMI filter as short as possible ( < 30cm )
otherwise use screened cable with a metal coupling nut and a metal clamp addle to connect
the shielded cable to the frequency inverter and metal grounding plate.
lThe only earth connection between the LISN and the test plate should be via the EMI filter.
lUse a motor which equals the power rating or below of the inverter rating.
lInstall a noise filter for inverter onto the output side of the primary circuitry can suppress
conducting noise (For residential environment only). To reduce radio active noise, use a
shielded wire between motor and drive, this wiring should be away from control wiring for
more than 30 cm.
Class B (Residential Environment)
U20AF__

12
Class A, Industrial Environment (only for drives built-in with EMC class A filter (U20----S)
lWhen the distance between the inverter and motor is longer than 100m, connection wire
should be carefully chosen to reduce the wiring resistance below 3% and the voltage drop
(V) = v3 x Wire resistance (Ω/km) x wire length (m) x current x 10-3
(B) Controlcircuitry wiring must be separatedterminated and away from theprimary power circuitry
and other high-voltage or large-current power lines to avoid noise interference.
lTo reduce the noise interference and avoid possible operational problems, shielded twisted
pair cable should be used to wire the control circuitry, as shown below. Connect the
shielding wire onto the grounding terminal. Only connect one end of the shield
Wiring distance must be under 50m.
(C) The grounding terminal of the inverter must be correctly grounded in compliance with local
codes.
lGrounding wire should be wired in accordance to electrical equipment (AWG) with the
length of the grounding wire as short as possible.
lThe grounding wire of the inverter must not be grounded together with other large current
loads (such as soldering machines or large current motors). They should be grounded
separately.
lGrounding circuitry must not be formed when grounding several inverters together.
