Note 1:
The wire for P, RB, and N connections should be MLFC wire (flame-retardant poly-flex wire, able to withstand
voltage of 600 V).
If the distance between the dynamic braking unit and a discharging resistor is 10 meters or more, use a cable
thicker than the specified wire size. Table 4.2 shows sizes of MLFC wire.
-1) If the distance is between 10 m (not including 10 m) and 25 m, use a wire size one rank larger.
-2) If the distance is between 25 m (not including 25 m) and 50 m, use a wire size two ranks larger.
However, the cable should be up to 5 m between the braking unit and the discharging resistor.
