Recommended Wire Sizes; Terminal Arrangement Diagrams And Screw Specifications - Fuji Electric frenic-hvac Instruction 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.

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 empty main circuit terminals marked with (NC) in the figures given below. Doing
so may break the inverter.
