2.4.3 System Wiring Diagram
Phase zeror
eactor
Used for reducing the radiation
interference, especially in the
places with audio devices, and
at the same time reducing the
interference of input end and
output ends as well.
Theeffective range is AM wave
band -10MHZ.
EMI filter
Used for reducing
electromagnetic interference.
Please refer to theappendix.
Brake
resistor
Used for shortening the
decelerating time ofmotor.
Please refer to the appendix.
AC reactor
(output end)
The length of motor wires will
influence the magnitude of the
reflection wave on the motor end.
When the engine wires are
longer than 20m, it is
recommended to install
the AC reactor.
Please refer to the appendix.
Power supply
Please use the power supply
in accordance with the rated
specification in the usage
manual.
Non-fuse
switch or
residual-current
circuit breaker
The input current may be
heavy when the power is
turned on. Adopt a proper non-
fuse switch or residual current
circuit breaker.
Electromagnetic
contactor
Please do not use the
electromagnetic contactor as
the power switch of AC drive,
since it will shorten the service
life of AC drive.
AC reactor
(input end)
When the output capacity is over
1000kVA, it is recommended to
add an AC reactor to improve
the functional factor. The
distance of wires should be
within 10m.

DC reactor
Improve power factor and
reduce AC pulse of DC bus.

For safty and small noise' AC drives
ground terminal EG should be well grounded.

■
Please do not connect the AC drive
with the output terminal (U/T1, V/T2
and W/T3) of AC drive;
otherwise it may cause AC drive damage.
■
Ensure that the screws of the main loop terminals are tightened to
prevent the sparks caused by the loose screw due to vibration.
■
The wires of main loop and those of control loop must be separated
to avoid mis
-
operation. If an intersection is needed, make them intersect
with a right angle.
■
Please use isolated cable and conduit,and connect with the two
ends of the shielding layer or conduit with ground.
■
If the installation place of the AC drive is extremely sensitive to
interference, please add an RFI filter in a place with a distance from the
