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

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.
