on this product act as both operating power terminals and as voltage measuring
terminals.
The layout of voltage input terminals is as follows.
Information
• R/S/T/N may be labeled U/V/W/O or L1/L2/L3/N in some cases.
• R/N/T may be labeled U/O/W or L1/N/L2 in some cases.
To wire the voltage input terminal, loosen the 3.5mm screw on the terminal panel, push the wire completely into the
terminal, and fix in place with the crimping terminal.
Information
• The terminal panel cover fixes in place when you open it fully so it won't get in your way when you are tightening the
screws, etc.
