2.2.5 Main circuit terminals
[ 1 ] Screw specifications and recommended wire size (main circuit terminals)
The specifications for the screws used in the main circuit wiring and the wire sizes are shown below. Exercise
caution as the terminal position varies depending on inverter capacity. In the diagram in "[ 2 ] Terminal layout
diagrams (main circuit terminals)”, the two ground terminals [*G] are not differentiated for the input side (primary
side) and the output side (secondary side).
Also, use crimped terminals with insulating sleeves compatible for main circuit or terminals with insulating tubes.
The recommended wire sizes are shown depending on cabinet temperature and wire type.
