For the FR-F820-02330(55K) or lower and FR-F840-01160(55K) or lower, the recommended cable size is that of the HIV cable (600V
class 2 vinyl-insulated cable) with continuous maximum permissible temperature of 75°C. Assumes that the surrounding air
temperature is 50°C or less and the wiring distance is 20m or less.
For the FR-F820-03160(75K) or higher, the FR-F840-01800(75K) or higher, and the FR-F842 models, the recommended cable size is
that of the LMFC cable (heat resistant flexible cross-linked polyethylene insulated cable) with continuous maximum permissible
temperature of 90°C. Assumes that the surrounding air temperature is 50°C or less (40°C or less for the FR-F842 models) and wiring
is performed in an enclosure.
