(*1): The recommended cable size is that of the cable (e.g. 600V class, HIV cable) with continuous maximum
permissible temperature of 75°C. The ambient temperature is assumed to be 40°C or below. (The interconnect
cable length is assumed to be 30m or less.)
(*2): For the control circuit, use shielded wires whose size (cross-section) is 0.75mm
2
or more.
(*3): For the earth cable, use wires larger than the specified ones in size (cross-section).
(*4): Recommended wire size for an optional braking resistor. Refer to instruction manual E6581386 5.19 for use of
external braking resistor.
