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.
