Use wires having the size (or larger) shown in the below table for the main circuit wiring shown in
the above figure. The applicable wire size range, applicable ring terminal and tightening torque for
the main circuit terminals are shown in the Table-1 for 400V Series, Table-2 for 500V Series and
Table-3 for 600V Series.
Listed ZMVV, Lugs shall be used & copper wire with 75°C (167°F) used for external connection.
