Recommended Wire Sizes; Terminal Arrangement Diagrams And Screw Specifications - Fuji Electric FRENIC-HVAC Manual

2.2.2 Recommended wire sizes

For the recommended wire sizes for the main circuits, refer to the "Conformity to the Low Voltage Directive in
the EU" and "Conformity with UL standards and CSA standards (cUL-listed for Canada)" given in Preface.
Crimp-style terminals for the main circuits should have insulation, insulation tubes, or similar treatment.

2.2.3 Terminal arrangement diagrams and screw specifications

The tables and figures given below show the screw specifications and terminal arrangement diagrams. Note
that the terminal arrangements differ depending on the inverter capacity.
Do not make wiring to unassigned main circuit terminals that are marked with ( ) in the figures given
below. Doing so may break the inverter.
