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.

Diagram A

Please wind each wire 4 times around the

core. The reactor must be put at inverter
output as close as possible.
