Conduits - Fuji Electric FRENIC-HVAC User Manual

2.4 Conduits

To ensure NEMA/UL Type 12 rating, mount conduits on the wiring plate in wiring. The conduits
should be selected according to the number of wires to be connected and the wire size.
Sections 2.4.1 give the sizes of the conduits to be applied when the wires of the recommended sizes are
used. Their sizes and mounting positions differ depending upon the inverter capacity.
