Diagram A
Wind each wire around the core for 4 times. The reactor
must be placed at the AC motor drive output side as
close as possible.
NOTE
600V insulated cable wire
1.
The table above gives approximate wire size for
the zero phase reactors but the selection is
ultimately governed by the type and the
diameter of the cable, i.e. the cable diameter
must small enough to go through the center of
the zero phase reactor.
2.
When wiring, do not goes through the earth
core. It only needs to pass through the motor
cable or the power cable.
3.
When a long motor cable for output is used, a
zero phase reactor may be necessary to reduce
the radiated emission.
Diagram B
Put the wires/cables through the middle of the 4 cores
that lines in parallel.
