Please wind each wire 4 times around the core.
The reactor must be placed at inverter output as
close as possible.

1. The table above gives approximate wire
size for the zero phase reactors but the
selection is ultimately governed by the type
and diameter of cable fitted i.e. the cable
must fit through the center hole of zero
phase reactors.
2. Only the phase conductors should pass
through, not the earth core or screen.
3. When long motor output cables are used an
output zero phase reactor may be required
to reduce radiated emissions from the
cable.
Figure B
Please put all wires through 4 cores in series
without winding.
