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

Note 1: The table above gives approximate
wire size for the zero phase reactors but the
B
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.
