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.
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.

Please put all wires through 4 cores in series without
winding.
