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

Note: 600V Insulated unshielded Cable
Note 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.
Note 2:
Only the phase conductors should pass
through, not the earth core or screen.
Note 3:
When long motor output cables are used
an output zero phase reactor may be required to
reduce radiated emissions from the cable
Diagram B
Please put all wires through 4 cores in series
without winding.
